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.
