Non-discrete position sensor utilizing photodiode surface resistance
PSD (Position Sensitive Detector) is an optoelectronic position sensor utilizing photodiode surface resistance. Unlike discrete element detectors
such as CCD, PSD provides continuous position data and features high position resolution and high-speed response.
PSD can be broadly divided into one-dimensional type and two-dimensional type. Two-dimensional type is further classified by structure into duo-
lateral type and tetra-lateral type. The duo-lateral type has superior position detection ability such as smaller position detection error and high
position resolution.
Listed in this catalog are typical two-dimensional type PSDs. Other types of PSDs such as one-dimensional type, electron beam detection type
and high-energy particle detection type are also available.
Features
l High position resolution
l Wide spectral response range
l High-speed response
l Simultaneous measurements of position and intensity
l Position is measured independent of light-spot size
l High reliability
Applications
l Optical position and angle sensing
l Remote optical control systems
l Automatic range finder systems
l Displacement and vibration monitors
l Laser beam alignment
l Medical equipment

*3: Position resolution
This is the minimum detectable light spot displacement. The detection limit is indicated by distance on the photosensitive
surface. The numerical value of the resolution of a position sensor using a PSD is proporional to both the length of the PSD
and the noise of the measuring system (resolution deteriorates) and inversely proportional to the photocurrent (incident
evergy) of the PSD (resolution improves).
· Light source: LED (900 nm)
· Photocurrent: 1 µA
· Spot Light size: φ200 µm
· Circuit system input noise: 1 µV (1 kHz)
· Frequency range: 1 kHz
· Interelectrode resistance: Typical value (Refer to specification table.)
