The AMI Series of Rangefinder Receivers with Processors from Analog Modules, Inc. is engineered to deliver highly accurate and reliable range data for advanced defense and electro-optical systems.
Designed for integration into compact military platforms, the 7558A and 7555 Series Rangefinder/Processor assemblies combine high-performance receiver technology with compact support electronics to provide corrected serial range outputs directly to a host system.
Built around the company’s proven receiver architectures, the assemblies integrate a high-performance receiver with onboard processing that calibrates range data using AMI’s patented correction technology. This capability mitigates range inaccuracies caused by signal disturbances such as range walk effects from return signal amplitude variations, enabling highly dependable measurements in operationally challenging environments.
Exceptional sensitivity — reaching down to 3 nW in the 7558 Series — enables operation with low-power lasers while also supporting long-range performance when mission requirements demand extended detection capability. The systems are optimized for multiple target scenarios and feature first, last, and strongest pulse selection, allowing operators and autonomous systems to prioritize and discriminate targets with precision.
Designed for demanding defense applications, the AMI Series incorporates time-programmed gain with noise tracking threshold, a high-speed range counter, and digitally adjustable avalanche photodiode (APD) bias, range gates, and false alarm rates. A built-in high-voltage bias supply for the APD detector further simplifies integration.
The 7558 Series additionally incorporates a thermoelectric cooler controller and heatsink, supporting enhanced detector performance in variable operating conditions. With a compact footprint that allows positioning close to optics, the modules minimize overall system size while maximizing efficiency for EO/IR payloads, laser rangefinders, targeting systems, and broader defense sensing applications. Custom optimization options are also available to meet specific mission requirements.
