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 suppressed by a high-pass 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 par titioned 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.
