Signal processing circuit for 2-D PSD

Signal processing circuit designed to facilitate operation of 2-D Position Sensitive Detector

Features

● No complicated adjustment required

Position measurement can be made simply by mounting 2-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 detection

Accurate position data can be obtained, independent of light intensity.

● Compact on-board configuration

A head amplifiers, signal addition/subtraction circuits, and analog divider are mounted on a compact PC board.

Applications

● Displacement measurements using 2-D PSD

● Various studies using 2-D PSD

● Evaluation of 2-D PSD
