光电传感器是将光信号转换为电信号的一种器件。其工作原理基于光电效应。光电效应是指光照射在某些物质上时,物质的电子吸收光子的能量而发生了相应的电效应现象。根据光电效应现象的不同将光电效应分为三类:外光电效应、内光电效应及光生伏*应。光电器件有光电管、光电倍增管、光敏电阻、光敏二极管、光敏三极管、光电池等。分析了光电器件的性能、特性曲线。

光电传感器一般由处理通路和处理元件2 部分组成。其基本原理是以光电效应为基础,把被测量的变化转换成光信号的变化,然后借助光电元件进一步将非电信号转换成电信号。光电效应是指用光照射某一物体,可以看作是一连串带有一定能量为的光子轰击在这个物体上,此时光子能量就传递给电子,并且是一个光子的全部能量一次性地被一个电子所吸收,电子得到光子传递的能量后其状态就会发生变化,从而使受光照射的物体产生相应的电效应。通常把光电效应分为3 类:(1 )在光线作用下能使电子逸出物体表面的现象称为外光电效应,如光电管、光电倍增管等;(2 )在光线作用下能使物体的电阻率改变的现象称为内光电效应,如光敏电阻、光敏晶体管等;(3 )在光线作用下,物体产生一定方向电动势的现象称为光生伏*应,如光电池等。
光电检测方法具有精度高、反应快、非接触等优点,而且可测参数多,传感器的结构简单,形式灵活多样,因此,光电式传感器在检测和控制中应用非常广泛。
光电传感器是各种光电检测系统中实现光电转换的关键元件,它是把光信号(可见及紫外镭射光)转变成为电信号的器件。
光电传感器
光电式传感器是以光电器件作为转换元件的传感器。它可用于检测直接引起光量变化的非电物理量,如光强、光照度、辐射测温、气体成分分析等;也可用来检测能转换成光量变化的其他非电量,如零件直径、表面粗糙度、应变、位移、振动、速度、加速度,以及物体的形状、工作状态的识别等。光电式传感器具有非接触、响应快、性能可靠等特点,因此在工业自动化装置和机器人中获得广泛应用。新的光电器件不断涌现,特别是CCD图像传感器的诞生,为光电传感器的进一步应用开创了新的一页。
由光通量对光电元件的作用原理不同所制成的光学测控系统是多种多样的,按光电元件(光学测控系统)输出量性质可分二类,即模拟式光电传感器和脉冲(开关)式光电传感器。模拟式光电传感器是将被测量转换
成连续变化的光电流,它与被测量间呈单值关系.模拟式光电传感器按被测量(检测目标物体)方法可分为透射(吸收)式,漫反射式,遮光式(光束阻档)三大类。所谓透射式是指被测物体放在光路中,恒光源发出的光能量穿过被测物,部份被吸收后,透射光投射到光电元件上;所谓漫反射式是指恒光源发出的光投射到被测物上,再从被测物体表面反射后投射到光电元件上;所谓遮光式是指当光源发出的光通量经被测物光遮其中一部份,使投射到光电元件上的光通量改变,改变的程度与被测物体在光路位置有关。
光敏二极管是较常见的光传感器。光敏二极管的外型与一般二极管一样,当无光照时,它与普通二极管一样,反向电流很小,称为光敏二极管的暗电流;当有光照时,载流子被激发,产生电子-空穴,称为光电
载流子。在外电场的作用下,光电载流子参与导电,形成比暗电流大得多的反向电流,该反向电流称为光电流。光电流的大小与光照强度成正比,于是在负载电阻上就能得到随光照强度变化而变化的电信号。
光敏三极管除了具有光敏二极管能将光信号转换成电信号的功能外,还有对电信号放大的功能。光敏三级管的外型与一般三极管相差不大,一般光敏三极管只引出两个极——发射极和集电极,基极不引出,管壳同样开窗口,以便光线射入。为增大光照,基区面积做得很大,发射区较小,入射光主要被基区吸收。工作时集电结反偏,发射结正偏。在无光照时管子流过的电流为暗电流Iceo=(1+β)Icbo(很小),比一般三极管的穿透电流还小;当有光照时,激发大量的电子-空穴对,使得基极产生的电流Ib增大,此刻流过管子的电流称为光电流,发射极电流Ie=(1+β)Ib,可见光电三极管要比光电二极管具有更高的灵敏度。
工作原理
光电传感器是通过把光强度的变化转换成电信号的变化来实现控制的。
光电传感器在一般情况下,有三部分构成,它们分为:发送器、接收器和检测电路。
发送器对准目标发射光束,发射的光束一般来源于半导体光源,发光二极管(LED)、激光二极管及红外发射二极管。光束不间断地发射,或者改变脉冲宽度。接收器有光电二极管、光电三极管、光电池组成。在接收器的前面,装有光学元件如透镜和光圈等。在其后面是检测电路,它能滤出有效信号和应用该信号。
此外,光电开关的结构元件中还有发射板和光导纤维。
分类和工作方式
⑴槽型光电传感器
把一个光发射器和一个接收器面对面地装在一个槽的两侧组成槽形光电。发光器能发出红外光或可见光,在无阻情况下光接收器能收到光。但当被检测物体从槽中通过时,光被遮挡,光电开关便动作,输出一个开关控制信号,切断或接通负载电流,从而完成一次控制动作。槽形开关的检测距离因为受整体结构的限制一般只有几厘米。
⑵对射型光电传感器,若把发光器和收光器分离开,就可使检测距离加大,一个发光器和一个收光器组成对射分离式光电开关,简称对射式光电开关。对射式光电开关的检测距离可达几米乃至几十米。使用对射式光电开关时把发光器和收光器分别装在检测物通过路径的两侧,检测物通过时阻挡光路,收光器就动作输出一个开关控制信号。
⑶反光板型光电开关
把发光器和收光器装入同一个装置内,在前方装一块反光板,利用反射原理完成光电控制作用,称为反光板反射式(或反射镜反射式)光电开关。正常情况下,发光器发出的光源被反光板反射回来再被收光器收到;一旦被检测物挡住光路,收光器收不到光时,光电开关就动作,输出一个开关控制信号。
⑷扩散反射型光电开关
扩散反射型光电开关的检测头里也装有一个发光器和一个收光器,但扩散反射型光电开关前方没有反光板。正常情况下发光器发出的光收光器是找不到的。在检测时,当检测物通过时挡住了光,并把光部分反射回来,收光器就收到光信号,输出一个开关信号。
没有信号输出的原因
首先要考虑的是接线或配置的问题。对于对射型光电传感器必须由投光部和受光部组合使用,两端都需要供电;而回归反射型必须由传感器探头和回归反射板组合使用;同时,用户必须给传感器提供稳定电源,如果是直流供电,必须确认正负极,如若正负极连接错误则会导致输出信号没有。
上述的原因分析是对光电传感器本身的考虑,我们还需要考虑的是检测物体的位置问题,如果检测物体不在检测区域,这样的检测是徒劳的。检测物体必须在传感器可以检测的区域内,也就是光电可以感知的范围内。其次,要考虑传感器光轴有没有对准问题,对射型的投光部和受光部光轴必须对准,对应的回归反射型的探头部分和反光板光轴必须对准。同样还要考虑的是检测物体是否符合标准检测物体或者小检测物体的标准,检测物体不能小于小检测物体的标准,从而避免导致对射型、反射型不能很好检测透明物体,像反射型对检测物体的颜色有要求,颜色越深,检测距离就越近。
如果以上情况都可以很明确地做出排除后,我们需要做的事就是检测环境的干扰因素。如光照强度不能超出额定范围;如果现场环境有粉尘,就需要我们定期清理光电传感器探头表面;或者是多个传感器紧密安装,互相产生干扰;还有一种影响比较大的是电气干扰,如果周围有大功率设备,产生干扰时必须要有相应的抗干扰措施。如果做过上述的逐一排查,这些因素都可以明确地排除还是没有信号输出的话,建议退回厂家检测判断。
结构分析
光电传感器通常由三部分构成,它们分别为:发送器、接收器和检测电路。
发射器带一个校准镜头,将光聚焦射向接收器,接收器出电缆将这套装置接到一个真空管放大器上。在金属圆筒内有一个小的白炽灯做为光源,这些小而坚固的白炽灯传感器就是如今光电传感器的雏形。
接收器有光电二极管、光电三极管及光电池组成。光敏二极管是现在较常见的传感器。光电传感器光敏二极管的外型与一般二极管一样,只是它的管壳上开有一个嵌着玻璃的窗口,以便于光线射入,为增加受光面积,PN结的面积做得较大,光敏二极管工作在反向偏置的工作状态下,并与负载电阻相串联,当无光照时,它与普通二极管一样,反向电流很小称为光敏二极管的暗电流;当有光照时,载流子被激发,产生电子-空穴,称为光电载流子。
此外,光电传感器的结构元件中还有发射板和光导纤维。角反射板是结构牢固的发射装置,它由很小的三角锥体反射材料组成,能够使光束准确地从反射板中返回。它可以在与光轴0到25的范围改变发射角,使光束几乎是从一根发射线,经过反射后,仍从这根反射线返回。
类型
⑴槽型光电传感器
把一个光发射器和一个接收器面对面地装在一个槽的两侧的是槽形光电。发光器能发出红外光或可见光,在无阻情况下光接收器能收到光。但当被检测物体从槽中通过时,光被遮挡,光电开关便动作。输出一个开关控制信号,切断或接通负载电流,从而完成一次控制动作。槽形开关的检测距离因为受整体结构的限制一般只有几厘米。
⑵对射型光电传感器
若把发光器和收光器分离开,就可使检测距离加大。由一个发光器和一个收光器组成的光电开关就称为对射分离式光电开关,简称对射式光电开关。它的检测距离可达几米乃至几十米。使用时把发光器和收光器分别装在检测物通过路径的两侧,检测物通过时阻挡光路,收光器就动作输出一个开关控制信号。
⑶反光板型光电开关
把发光器和收光器装入同一个装置内,在它的前方装一块反光板,利用反射原理完成光电控制作用的称为反光板反射式(或反射镜反射式)光电开关。正常情况下,发光器发出的光被反光板反射回来被收光器收到;一旦光路被检测物挡住,收光器收不到光时,光电开关就动作,输出一个开关控制信号。
⑷扩散反射型光电开关
它的检测头里也装有一个发光器和一个收光器,但前方没有反光板。正常情况下发光器发出的光收光器是找不到的。当检测物通过时挡住了光,并把光部分反射回来,收光器就收到信号,输出一个开关信号。

①检测距离长
如果在对射型中保留10m以上的检测距离等,便能实现其他检测手段(磁性、超声波等) 无法远距离检测。
②对检测物体的限制少
由于以检测物体引起的遮光和反射为检测原理,所以不象接近传感器等将检测物体限定在金属,它可对玻璃、塑料、木材、液体等几乎所有物体进行检测。
③响应时间短
光本身为高速,并且传感器的电路都由电子零件构成,所以不包含机械性工作时间,响应时间非常短。
④分辨率高
能通过高级设计技术使投光光束集中在小光点,或通过构成特殊的受光光学系统,来实现高分辨率。也可进行微小物体的检测和高精度的位置检测。
⑤可实现非接触的检测
可以无须机械性地接触检测物体实现检测,因此不会对检测物体和传感器造成损伤。因此,传感器能长期使用。
⑥可实现颜色判别
通过检测物体形成的光的反射率和吸收率根据被投光的光线波长和检测物体的颜色组合而有所差异。利用这种性质,可对检测物体的颜色进行检测。
⑦便于调整
在投射可视光的类型中,投光光束是眼睛可见的,便于对检测物体的位置进行调整。
用光电元件作敏感元件的光电传感器,其种类繁多,用途广泛。按光电传感器的输出量性质可分为两类:(1 )把被测量转换成连续变化的光电流而制成的光电测量仪器,可用来测量光的强度以及物体的温度、透光能力、位移及表面状态等物理量。例如:测量光强的照度计,光电高温计,光电比色计和浊度计,预防火灾的光电报警器,构成检查被加工零件的直径、长度、椭圆度及表面粗糙度等自动检测装置和仪器,其敏感元件均用光电元件。半导体光电元件不仅在民用工业领域中得到广泛的应用,在军事上更有它重要的地位。例如用硫化铅光敏电阻可做成红外夜视仪、红外线照相仪及红外线导航系统等;(2 )把被测量转换成继续变化的光电流。利用光电元件在受光照或无光照射时" 有" 或"无"电信号输出的特性制成的各种光电自动装置。光电元件用作开关式光电转换元件。例如电子计算机的光电输入器,开关式温度调节装置及转速测量数字式光电测速仪等。
一、烟尘浊度监测仪
防止工业烟尘污染是环保的重要任务之一。为了消除工业烟尘污染,首先要知道烟尘排放量,因此必须对烟尘源进行监测、自动显示和超标报警。烟道里的烟尘浊度是用通过光在烟道里传输过程中的变化大小来检测的。如果烟道浊度增加,光源发出的光被烟尘颗粒的吸收和折射增加,到达光检测器的光减少,因而光检测器输出信号的强弱便可反映烟道浊度的变化。
二、条形码扫描笔
当扫描笔头在条形码上移动时,若遇到黑色线条,发光二极管的光线将被黑线吸收,光敏三极管接收不到反射光,呈高阻抗,处于截止状态。当遇到白色间隔时,发光二极管所发出的光线,被反射到光敏三极管的基极,光敏三极管产生光电流而导通。整个条形码被扫描过之后,光敏三极管将条形码变形一个个电脉冲信号,该信号经放大、整形后便形成脉冲列,再经计算机处理,完成对条形码信息的识别。
三、产品计数器
产品在传送带上运行时,不断地遮挡光源到光电传感器的光路,使光电脉冲电路产生一个个电脉冲信号。产品每遮光一次,光电传感器电路便产生一个脉冲信号,因此,输出的脉冲数即代表产品的数目,该脉冲经计数电路计数并由显示电路显示出来。
四、光电式烟雾报警器
没有烟雾时,发光二极管发出的光线直线传播,光电三极管没有接收信号。没有输出,有烟雾时,发光二极管发出的光线被烟雾颗粒折射,使三极管接受到光线,有信号输出,发出报警。
五、测量转速
在电动机的旋转轴上涂上黑白两种颜色,转动时,反射光与不反射光交替出现,光电传感器相应地间断接收光的反射信号,并输出间断的电信号,再经放大器及整形电路放大整形输出方波信号,后由电子数字显示器输出电机的转速。
六、光电池在光电检测和自动控制方面的应用
光电池作为光电探测使用时,其基本原理与光敏二极管相同,但它们的基本结构和制造工艺不*相同。由于光电池工作时不需要外加电压;光电转换效率高,光谱范围宽,频率特性好,噪声低等,它已广泛地用于光电读出、光电耦合、光栅测距、激光准直、电影还音、紫外光监视器和燃气轮机的熄火保护装置等。
应用案例
光电传感器应用于激WQ
由于光电传感器对红外辐射,或可见光,或对二者都特别灵敏,因而就更加容易成为激光攻击的目标。此外,电子系统及传感器本身还极易受到激光产生的热噪声和电磁噪声的干扰而无法正常工作。战场上的激光WQ攻击光电传感器的方式主要有以下几种:用适当能量的激光束将传感器“致盲",使其无法探测或继续跟踪已经探测到的目标。或者,如果传感器正在导引WQ飞向目标,则致盲将使其失去目标。综上所述,由于传感器在战场上发挥的作用越来越重要,同时又很容易遭受激光攻击,它们已成为低能激光WQ的目标。
光电传感器应用于自动抄表系统
随着微电子技术、传感器技术、计算机技术及现代通讯技术的发展,可以利用光电传感器来研制自动抄表系统。电能表的铝盘受电涡流和磁场的作用下产生的转矩驱动而旋转。采用光电传感器则可将铝盘的转数转换成脉冲数。如:在旋转的光亮的铝盘上局部涂黑,再配以反射式光电发射接收对管,则当铝盘旋转时,在局部涂黑处便产生脉冲,并可将铝盘的转数采样转换为相应的脉冲数,并经光电耦合隔离电路,送至CPU的T0端口进行计数处理。采用光电耦合隔离器可有效地防止干扰信号进入微机。再结合其它传输方式便可以形成自动抄表系统。
光电传感器应用于监控烟尘污染
光电传感器是一种小型电子设备,它可以检测出其接收到的光强的变化,通过把光强度的变化转换成电信号的变化实现控制功能。由于光电式传感器具有非接触、响应快、性能可靠等特点,因此在工业自动化装置和机器人中获得广泛应用,而我们可以利用光电传感器的特性来检测烟尘的情况,因而光电传感器输出信号的强弱便可反映烟道浊度的变化。
卫生级防冲洗型光电传感器
防冲洗型传感器,能够提供*的可靠性和舒适性,并将运行成本降至低。配合IO-Link接口以及能够大幅延长使用寿命的proTect+密封理念,这两款新型传感器适用于苛刻的应用环境,堪称食品和饮料行业的理想解决方案。
1)暂态响应范围宽,谐波测量能力强
暂态特性的优劣是判断一种互感器能否在电力系统中获得应用的一个重要参数,特别是与继电保护动作时间的配合。传统电磁式互感器由于存在铁芯,对高频信号的响应特性较差,不能正确反映一次侧的暂态过程。而光电互感器传测量的频率范围主要由电子线路部分决定,没有铁芯饱和的问题,因此能够准确反映一次侧的暂态过程。一般可设计到0.1 Hz到1 MHz,特殊的可设计到200 MHz的带通。光电传感器的结构可以测量高压电力线路上的谐波。而电磁感应互感器是难以达到的。
2)数字接口,通信能力强
由于光电传感器下传的就是光数字信号,与通信网络容易接口,且传输过程中没有测量误差。同时随着微机化的保护控制设备的广泛采用,光电互感器可以直接向二次设备提供数字量,这样就能省去原来保护装置中的变换器和A/D采样部分,使二次设备得到大大的简化,推动保护新原理的研究。
3)体积小,重量轻、易升级,满足变电站小型化与紧凑型的要求,由于光电传感器是靠传感头和电子线路进行信号的获取和处理,体积小,重量一般在 1000 kg以下,便于集成在AIS或GIS中,这样将大大减少变电站的占地面积,满足变电站小型化和紧凑化的要求。同时光电互感器通过少量光缆与二次设备连接,可使电缆沟和电缆大为减。
光电传感器的主要应用领域:车载娱乐/导航/DVD系统背光控制,以便在所有的环境光条件下都可以显示出理想的背光亮度;后座娱乐用显示器背光控制;仪表组背光控制(速度计/转速计);自动后视镜亮度控制(通常要求两个传感器,一个是前向的,一个是后向的);自动前大灯和雨水感应控制(,根据需求进行变化);后视相机控制(,根据需求进行变化)。在提供更舒适的显示质量方面已经成为较有效的解决方案之一,它具有与人眼相似的特性,这对于汽车应用而言至关重要,因为这些应用要求在所有环境光条件下都能达到*的背光效果。例如,在白天,用户需要大的亮度来实现的可见度,但是这种亮度在对于夜间条件而言则是过亮的,因此带有良好光谱响应 (良好的IR衰减)的光传感器、适当的动态范围和整体的良好输出信号调节可以很容易地自动完成这些应用。终端用户可以设置几个阈值水平(如低、中、亮光),或能够随意地动态地改变传感器的背光亮度。这也适用于汽车后视镜亮度控制,当镜子变暗和/或变亮时需要智能的亮度管理,可以通过环境光传感器来完成。
对于便携式应用,如果用户不改变系统设置(通常是亮度控制),那么一个显示器总是消耗同样多的能量。在室外等特别亮的区域,用户倾向于提高显示器的亮度,这就会增加系统的功耗。而当条件变化时,如进入建筑物,大多数用户都不会去改变设置,因此系统功耗仍然保持很高。但是,通过使用一个光传感器,系统能够自动检测条件变化并调节设置,以保证显示器处于的亮度,进而降低总功耗。在一般的消费类应用中,这也能够延长电池寿命。对于电话、笔计本电脑、PAD和数码相机,通过采用环境光传感器反馈,可以自动进行亮度控制,从而延长了电池寿命。
并不是一个新的构想。在数十年前就已经利用光电二极管和光敏电阻来实现这一构想。所谓新构想,是指对环境光感应的同时还能消减无用的红外线和紫外线光,而且在支持汽车规格AECQ-1000严格要求的同时还可以实现小封装,尤其是能够保证在-40度至+105度(2级)温度范围内的操作,以满足其余的规格要求。如何保持工作质量标准并满足AECQ-1000的2级工作要求,这是当今在所有光设计解决方案中所面临的挑战。采用一个光传感器或LED发射器或接收器时,任何的光学解决方案都会面临着暴露在恒定高温下(>+85度)而出现的封装变色问题(会变暗或变成淡黄)。同样值得一提的是,到目前为止,所有环境光传感器的应用都限于车舱内,在发动机舱或户外环境中还没有出现光传感器应用。事实上,即使出现了这样的应用,光封装也不是针对这样的苛刻条件(+125或+150度的条件)而设计,因此,在当前的光学封装技术下,它们很可能还不能够承受这样的条件。
半导体相似传感器和封装开发的进展使得终端用户在光传感器上具有了更广泛的选择。小封装、低功耗、高集成和简单易用性是设计者更多地采用光传感器的原因,其应用范围涉及消费类电子、工业应用以及汽车领域。
1、用于目标跟踪和坐标定位256光电管阵列四象限CMOS光电传感器
将传统的象限传感器与当前迅速发展的CMOS图象传感器相结合,提出了使用有源传感阵列感光的256单元光电管阵列四象限CMOS光电传感器。
该传感器的感光单元采用了CMOS图象传感器中使用的有源像素传感器(Active Pixel Sensor,APS)设计,在感光单元内部由光电信号预处理电路直接将传感产生的光电信号转化为幅度较大的电信号输出,避免了对微弱信号的处理,降低了噪声的影响。传感器应用阵列采集光信号,可以直接确定目标光源的坐标位置并实现一步到位的快速调整。传感器使用标准CMOS工艺制造,将传感阵列与信号处理电路集成在同一芯片上,可以实现传感器的SOC集成和智能化(Smart Sensor)设计。广泛应用于激光的瞄准、制导、跟踪,搜索装置,精密测量,如激光微定位、位移监控、精密机床的光电控制等领域。是一种用于目标跟踪和坐标定位的新型集成阵列四象限CMOS光电传感器。

国内外光电传感器的研究现状
由于光电传感器的应用涉及的领域非常广泛,其研究和开发在世界上引起了高度重视,各国更是竞相研究开发并引起激烈的竞争。从初的应用于军事逐渐发展到民事,而且与我们的生活息息相关,应该说现代化的生活离不开光电传感器的参与,如传真机、复印机、扫描仪、打印机、车库开门器、液晶显示器、色度计、分光计、汽车和医疗诊断仪器等等不胜枚举。
美国是研究光电传感器起步早、水平高的国家之一,在军事和民用领域的应用发展得十分迅速。在军事应用方面,研究和开发主要包括:水下探测、航空监测、核辐射检测等。美国也是早将光电传感器用于民用领域的国家。如运用光电传感器监测电力系统的电流、温度等重要参数,检测肉类和食品的细菌和病毒等。美国拥有世健全的光电传感器产品线,超过12000种产品包括自含式或放大器分离型,限位开关外型或小型传感器,精密检测或长距离检测传感器,检测距离长达305m。并且拥有行业内较齐全的标准光纤和定制光纤产品。大部分产品防护等级达到NEMA6P和IP67。日本和西欧各国也高度重视并投入大量经费开展光电传感器的研究与开发。20世纪90年代,研究开发出多种具有水平的民用光电传感器,日本的电器以价格适中质量好而响誉。西欧各国的大型企业和也积极参与了光电传感器的研发和市场竞争。我国对光电传感器研究的起步时间与相差不远。已有上百个单位在这一领域开展工作,主要是在光电温度传感器、压力计、流量计、液位计、电流计等领域进行了大量的研究,取得了上百项科研成果,有的达到
但与发达国家相比,我国的研究水平还有不小的差距,主要表现在商品化和产业化方面,大多数品种仍处于实验研制阶段,还无法投入批量生产和工程化应用。
