Question

光敏晶体管有光敏二极管和光敏三极管两大类。在光控电路中使用光敏器件也以光敏二极管和光敏三极管为主。光敏二极管和光敏三极管是光电转换半导体器件，与光敏电阻器相比具有灵敏度高，高频性能好，可靠性能好，可靠性好，体积小。使用方便等优点。光敏三极管常用于测量光亮度，比如根据光亮度自动控制的开关，可以达到节约能源的目的。光敏三极管的另一个作用是传输信号，光耦合器亦称光电隔离器，简称光耦。光耦合器以光为媒介传输电信号。它对输入、输出电信号有良好的隔离作用。光敏三极管另一个优点，他还可以接受红外线，我认为这点很有用处。因为在晚上没有可见光，但是仍然有红外线，因此可以作为夜视装置，可以用来防盗。
此次设计采用CSY-998G光电传感器试验仪实验平台，利用光电导效应是半导体材料的一种体效应，建立实验系统，测试光敏三极管等光敏晶体管的伏安特性。以光敏二极管和光敏三极管的伏安特性作为设计实验的基础。采用型号为2CU2B的光敏二极管和型号为3DU33的光敏三极管作为研究对象，从光敏二极管的光照特性和光谱特性，光敏三极管的伏安特性、光照特性和相应波长进行试验。试验结果表明光敏晶体管具有很高的应用价值，用途十分广泛，能够胜任人们各种生产，生活的需要。达到了预期设计的目的。

Answer 1

Photo transistor is photosensitive diode and light activated triode two categories. In the electric circuit device with photosensitivity photosensitive diodes and light activated triode. Photosensitive diode and light activated triode is photoelectric conversion semiconductor devices, and photosensitive resistors compared with high sensitivity, high performance, reliable performance, reliable quality, smaller volume. Convenient use, etc. Light activated triode often used for measuring brightness, such as automatic control switch according to the brightness, can achieve the purpose of saving energy. Light activated triode is another function signal transmission, optical coupler, also called photoelectric isolation light-coupler referred to. Optical coupler light for media transmission signals. It for input and output signal has good effect of segregation. Another advantage light activated triode, he can accept, I think it's infrared ray. Because no visible in the evening, but still have infrared night-vision equipment, and thus can be and can be used as a burglar.
This design USES CSY - 998G photoelectric sensor test instrument experimental platform, use light conductance effect is a body of semiconductor material experiment system, establish the effects of light activated triode test the volt-ampere characteristics of photo transistor, etc. In photosensitive diode and the volt-ampere characteristics of light activated triode as design experiment basis. Using model for 2CU2B photosensitive diode and the model for the light activated triode 3DU33 as the research object, the light from photosensitive diode characteristics and spectral characteristics and the volt-ampere characteristics of light activated triode, illumination characteristics and corresponding wavelength test. Test results show that photo transistor high application value, widely used, can be competent people, life needs of production. Achieve the expected purpose of design.

Answer 2

Photosensitive transistor has photodiode and photosensitive audion two major kinds. Use photosensitive component also to give first place to photodiode and photosensitive audion in light-operated circuit. Photodiode and photosensitive audion are a photoelectricity change semiconductor device , to have sensitiveness height , the high frequency function is good , the reliability energy is good , reliability is good , volume is small compared with photosensitive electrical resistor. Be put into use waiting for merit conveniently. Photosensitive audion is often used to measure a radiance, for instance , the switch according to radiance autocontrol , can achieve energy saving's purpose. Another photosensitive audion effect is transmission signal , photo-coupler also says photoelectricity isolator , the shorter form glorify a couple. Photo-coupler takes brightness as intermediary transferring an electric signal. It has fine buffer action to the electric signal importing , outputing. Another merit , he return photosensitive audion back being able to accept infrared ray , I think that this is of use very much. Do not have visible light, but still do not have infrared ray because of at night, therefore, can be the night vision device , can be used to guard against theft. The platform designing that the photoelectricity sensor tests the instrument experiment this time adopt CSY-998G , the system making use of the photoconductance effect to be one kind of body effect of semiconductor materials , building an experiment, test photosensitive audion waiting for photosensitive transistor volt-ampere characteristic property. The volt-ampere characteristic property with photodiode and photosensitive audion is the basis designing an experiment's. Photosensitive audion adopt a type to be that 2 CU2B photodiode and types are 3 DU33 is an object of study , characteristic property composes in reply spectrum characteristic property from the photodiode illumination , characteristic property and corresponding wavelength carry out photosensitive audion volt-ampere characteristic property , illumination experiment. Value , use testing that result indicates photosensitive transistor having very high application are very broad , are able to be competent for people various need giving birth to a child , living. Have reached the purpose expecting to design that.
