OPTICAL POSITION-SENSITIVE DETECTOR (PSD)

Rev D3, Page 2/9

DESCRIPTION

The iC-OD/L device is an optical position sensi-

tive detector with a monolithic integrated photodiode.

The device supersedes one PSD and two conven-

tional photoelectric detectors, e.g. in motion sensors.

Constant light and low-frequency variing light are

suppressed by a highpass filter.

A lowpass filter

reduces high-frequency interference to a minimum.

The maximum sensitivity for alternating-light signals

(for AC photoelectric currents) is about 100 kHz, with

a current amplification of typically 48 dB.

The photoelectric current is partitioned to the two

photocurrent amplifiers according to the position of

the light signal. The analogue outputs IAC1 and IAC2

offer directly the amplified AC photoelectric current.
