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 Applications No complicated adjustments required Position measurement of a light spot can be made simply by mounting 2-D PSD. Displacement measurements using DC light 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). Various studies using 2-D PSD Performance evaluation of 2-D PSD 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.
