PSD signal processing circuit
Features
No complicated adjustments required
Position measurements can be made by just connecting to a PSD and power supply (±15 V).
The position (mm) of a spot light from the PSD center is obtained as an output voltage (V).
(except C3683-01)
Stable position detection
Accurate position data can be detected independent of incident light intensity.
Compact size
Head amplifiers, signal addition/subtraction circuits, and analog divider are mounted on a
compact PC board.

AC signal processing circuit ···············································
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.
