Signal processing circuit for 1-D PSD
C3683-02
Circuit board for easier 1-D PSD operation
The C3683-02 is a DC signal processing circuit for one-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 1-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 a 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 1-D PSD
Performance evaluation of 1-D PSD
