PSD signal processing circuit

Position measurements can be made by just connecting to a PSD and power supply (±15 V).

l The position (mm) of a spot light from the PSD center is obtained as an output voltage (V).

(except C3683-01)

Accurate position data can be detected independent of incident light intensity.

Head amplifiers, signal addition/subtraction circuits, and analog divider are mounted on a

compact PC board.

Designed specifically for DC light detection.

Designed specifically for pulse (AC) signal detection.

Has a synchronous circuit, S/H (sample & hold) circuit and LED driver circuit.

Use of a pulse-driven LED ensures reliable operation even under background light.
