Various methods are available for detecting the position of incident light. These
include methods using small discrete detector arrays or multi-element sensors such
as CCD sensors. In contrast to these sensors, PSDs (Position Sensitive Detectors)
are comprised of a monolithic detector with no discrete elements and provide
continuous position data by making use of the surface resistance of the photodiode.
PSDs offer advantages such as high position resolution, high-speed response and
reliability.
What is PSD
· Excellent position resolution
· Wide spectral response range
· High-speed response
· Detects center-of-gravity position of spot light
· Simultaneously detects light intensity and center-of-gravity position of spot light
· High reliability
