Applications and Circuits of Photoresistors
Photoresistor is one of the photoelectric sensor elements, which is a kind of element made by the photoconductivity effect of semiconductor. The resistance value changes with the intensity of the incident light. Generally speaking, the incident light increases, the conductivity increases, and the resistance value decreases. Generally, the photoresistor body is made into a thin film structure to absorb more light energy. The material used for the photosensitive layer of the photoresistor can be polycrystalline material or single crystal material, and single crystal material can be made into intrinsic type and Doped type.
How to choose an op-amp?
Op-amp is the cornerstone of the whole analog circuit design, and choosing a proper amplifier is crucial to achieving the system design specifications.
Compared with structured light and binocular stereo vision, what are the advantages of ToF technology?
Time of Flight (ToF), Structured Light (Structured Light), and Stereo Vision (Stereo Vision) together form the current three mainstream technology routes for 3D imaging and sensing. Among them, the 3D structured light solution is the most mature and has been widely used in industrial 3D vision. ToF has become a more promising solution on the mobile side by virtue of its own advantages.
