PSD (1 Dimension)
PSD Position Sensitive Detector
It is a semiconductor device that detects the coordinate information of the center of gravity of a light point based on the lateral photoelectric effect
It has the advantages of high resolution, fast response speed, and simple signal processing,
Especially suitable for non-contact high-precision rapid measurement and collimation of displacement, distance, angle, and other physical quantities that can be indirectly converted into light point position or displacement.
Array products include products arranged in a certain positional relationship by more than one emitting or receiving unit,
Products that achieve non single point functionality, including one-dimensional/two-dimensional PSD, Dual PD, four quadrant, etc
Array products come in various forms such as circular array layout, linear array layout, or planar array layout
Some products are customized according to customer requirements or specific applications and will not be displayed
Dual PD
The dual PD consists of two highly sensitive photodiodes, with various light receiving areas and packaging options available
By utilizing its unique layout structure and excellent optoelectronic characteristics, it can be widely used in ranging, centering, offset measurement, and other applications
■ For Postion、Distance
A four quadrant photodetector is a photodetector device that arranges four photodiodes with identical performance in a four quadrant Cartesian coordinate system
The widely used multivariate non imaging photodetectors in optoelectronic detection systems are mostly four quadrant photodetectors (hereinafter referred to as four quadrants). It includes various specifications of silicon photocells and various types of four quadrant photodiodes, such as four quadrant PIN photodiodes, four quadrant avalanche photodiodes, etc.
