Study On Photoelectric Sensing System Based On Condensing And Filtering Components

The rapid development of photoelectric sensing and related technologies has met the higher requirements of various control devices and systems and improves automation of various fields.The importance continues to increase.In this thesis,a variety of photoelectric transformation system are designed and simulated,i.e.photoelectric sensor based on curved surface light collector,a photoelectric sensor for weak light detection,a high-sensitivity photoelectric sensor device,an indoor concentrating device for multiple light sources,a high-sensitivity photoelectric sensor with multi-direction focusing,and an enzyme reaction detection device based on fluorescent dye.This type of design would collect the light more efficiently.Furthermore,combining it with the color filter helps the energy of the emitted light to be highly concentrated,and improves the wavelength screening of light.Highly sensitive photoelectric sensor system based on the light-collecting and screening component are achieved.The system condenses as much light as possible in the environment through the condensing system in a small area by converging light.The photoelectric sensor only needs to focus on the photosensitive surface of the device,thereby greatly reducing the amount of sensor.and semiconductor material.An organic light-emitting diode(OLED)based system was prepared with light concentrating and filtering components.The convergence and selection of light enables the photoelectric sensor to respond more accurately to the light with specific wavelength,with high efficiency and low loss.
