An avalanche photodiode (APD) receiver claims to have established a benchmark for rangefinding applications.
The highly sensitive ROX LRFR reduces laser pulse energy requirements by a factor of five or greater, or it can extend the standoff range of existing lasers by two times or more.
Sensitive throughout the 950-nm to 1550-nm spectrum, including the eye-safe spectral range beyond 1400-nm, ROX LRFRs are designed for industry-leading sensitivity, high dynamic range (70dB) and high damage threshold (5MW/cm²).
Wide spectral response allows compatibility with older generations of 1064-nm lasers as well as newer, eye-safe 1550-nm lasers.
The application achieves levels of performance by integrating Voxtel’s low noise deschutes indium gallium arsenide (InGaAs) avalanche photodiodes (APDs) with custom detector biasing and signal-conditioning application-specific integrated circuits (ASICS), programmable configuration and control processing circuits, into a hermetic TO-8 package
