■ HIGH SENSITIVITY DOWN TO 3 nW ■ AVAILABLE WITH PIN OR APD DETECTOR ■ HIGH SPEED RANGE COUNTER ■ DIGITALLY ADJUSTABLE APD BIAS, RANGE GATES AND FALSE ALARM RATE ■ DUAL RANGE TIME PROGRAMMED GAIN ■ BUILT-IN HV BIAS SUPPLY FOR APD DETECTOR
DESCRIPTION:
The 7551 Laser Rangefinder Receiver/Processor assembly comprises a high performance InGaAs receiver (PIN or APD) with compact support electronics to provide corrected range data to a host system. The serial range data output is calibrated using AMI’s patented technology to mitigate the effects of range errors from various sources including walk due to return signal amplitude variations. Exceptional sensitivity allows the use of low power lasers, or alternatively, long range operation. The module provides high voltage bias, time programmed gain, first, last or strongest pulse selection, range gating as well as a number of user-controlled options via the serial interface. The compact layout allows positioning at the optics for minimum overall system size.
