Signal processing circuit for 2-D PSD
C4674-01
Circuit board for easier 2-D PSD operation
The C4674-01 is a DC signal processing circuit for two-dimensional PSD. It is suitable for displacement measurements using
DC light.
Features
No complicated adjustments required
Position measurement of a light spot can be made
simply by mounting 2-D PSD.
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).
Accurate position sensing
Position data of light spot is independent of incident
light intensity.
Three sensitivity ranges
Compact design
Head amp, signal addition/subtraction circuits, and
analog divider circuit are mounted on a compact PC
board.
Applications
Displacement measurements using DC light
Various studies using 2-D PSD
Performance evaluation of 2-D PSD
