Laser Rangefinder Receivers With Range Processors

The 7555 Series Rangefinder/Processor assemblies comprise a high-performance Model 755A receiver with compact support electronics to provide corrected range data to a mother 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 modules provide high voltage bias, time programmed gain with noise tracking threshold, first, last, and strongest pulse selection and range gating. There also are a number of user-controlled options via the serial interface. The compact layout allows positioning at the optics for minimum overall system size.
Custom options and optimization are available.

  • High Sensitivity down to 3nW
  • Fast Recovery from Overload
  • Optimized for Multiple Targets
  • Time Programmed Gain with Noise Tracking Threshold
  • High Speed Range Counter
  • Range Walk Correction to 1m RMS
  • Digitally adjustable: APD Bias, Range Gates, False Alarm Rate
  • Built-in HV Bias Supply for APD Detector
