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 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.
