Signal processing circuit for 1-D PSD

Circuit board for easier 1-D PSD operation

Features

● No complicated adjustments required

Position can be measured just by installing a 1-D PSD on

the board.

● Accurate position sensing

Use of pulse-driven LED allows accurate position sensing

even under background light, and independent of pulsed

light intensity.

● Compact design

An LED drive circuit, head amp, signal addition/subtraction

circuits, sample hold circuit, synchronization circuit and

analog divider circuit are mounted on a compact PC board.

Applications

● Displacement measurements using pulsed light synchronized

with the circuit

● Various studies using 1-D PSD

● Performance evaluation of 1-D PSD
