OPTICAL POSITION-SENSITIVE DETECTOR (PSD)

DESCRIPTION
The iC-OD/L device is an optical position sensitive
detector with a monolithic integrated photodiode. The
device supersedes one PSD and two conventional
photoelectric detectors, e.g. in motion sensors.
Constant light and low-frequency variing light are sup-
pressed by a highpass filter. A lowpass filter reduces
high-frequency interference to a minimum. The max-
imum sensitivity for alternating-light signals (for AC
photoelectric currents) is about 100 kHz, with a cur-
rent amplification of typically 48 dB.
The photoelectric current is partitioned to the two pho-
tocurrent amplifiers according to the position of the
light signal. The analogue outputs IAC1 and IAC2
offer directly the amplified AC photoelectric current.
