A position sensitive device and/or position sensitive detector (PSD) is an optical position sensor (OPS) that can measure a position of a light spot in one ...
Position Sensing Detectors PSD's are silicon photodiodes that provide an analog output directly proportional to the position of a light spot on the detector ...
由 H Andersson 著作 · 2008 · 被引用 57 次 — Position sensitive detectors are used to measure, with great accuracy and speed, the position of a light spot incident on the surface. Their main use is for.
The PSD is used in a wide range of fields such as measurements of position, angles, distortion, vibration, and lens reflection/ refraction. Applications also ...
The PDQ80A and PDQ30C detectors are segmented, position-sensing, quadrant detectors for precise path alignment of light in the 400 to 1050 nm or 1000 to 1700 nm ...
Position-sensitive detectors are photodetectors with which one can measure the position of a light spot in one or two dimensions, normally with a relatively ...
One-dimensional PSDs have a long, narrow photosensitive area and detect positions in a longitudinal direction. Suitable for use in displacement meters and ...
Position-sensitive diodes (PSD). These components utilize the effect of the lateral division of the generated photocurrent. The term position sensitive ...
