AMI Series of Rangefinder Receivers with Processors

Laser Rangefinder Receiver and Processor Modules
The 7558 and 
 7555 Series Rangefinder/Processor assemblies comprise a high performance Model 758A or 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. The 7558 series offers a TE cooler controller and heatsink. 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 3 nW (7558 Series)
  • Fast Recovery from Overload
  • Optimized for Multiple Targets
  • Cooled Detector (7558 Series)
  • Time Programmed Gain with Noise Tracking Threshold
  • High Speed Range Counter
  • Range Walk Correction to 1 m RMS
  • Digitally adjustable: APD Bias, Range Gates, False Alarm Rate
  • Built-in HV Bias Supply for APD Detector

Model 758B.1

Based on the field proven performance of AMI’s 758 Series Laser Rangefinder Receivers, the Model 758B.1 extends the capabilities even further with outstanding double-pulse discrimination. This allows a weak target to be seen through a close, partly obscuring strong target. Multiple Target Resolution is 12 meters typical over 6 orders of magnitude with the second pulse 10dB down.
