Features
l
No complicated adjustment required
Position measurement can be made simply by mounting
2-D PSD.
l
Output voltage directly representing the position data
The position (mm) of a light spot from the PSD center is
obtained as an output voltage (V).
l
Accurate position detection
Accurate position data can be obtained, independent of
light intensity.
l
Compact on-board configuration
A head amplifiers, signal addition/subtraction circuits, and
analog divider are mounted on a compact PC board.
Applications
l
Displacement measurements using 2-D PSD
l
Various studies using 2-D PSD
l
Evaluation of 2-D PSD
