01 / Product introduction

Product introduction

A high-performance very-long-range ranging module pairing a 1535 nm eye-safe erbium-glass laser with a high-sensitivity photoelectric receiver. It reaches beyond 12 km against large structures and terrain while staying compact at ≤140 g, and integrates into civil UAV and manned-aircraft electro-optical gimbals, industrial inspection equipment, high-altitude meteorological systems and smart security terminals.

02 / Core application scenarios

Core application scenarios

01
Civil aviation and wide-area geographic surveyVery-long-range terrain measurement from UAVs and general-aviation aircraft, high-precision 3D GIS modelling and remote assessment of disaster sites.
02
High-altitude meteorology and environmental monitoringReal-time cloud-base measurement (ceilometry), vertical aerosol distribution profiling, and long-range sensing of high-altitude wind fields and meteorological variables.
03
Major infrastructure and safety monitoringMicro-displacement and deformation monitoring of large dams, sea-crossing bridges and high-rise structures, plus long-range safety clearance measurement on high- and extra-high-voltage transmission lines.
04
Long-range security and port managementPerimeter protection across very large sites, and long-range civil target monitoring at major airports and busy port channels.

03 / Core advantages

Core advantages

01
1535 nm eye-safe operationThe 1535 nm band meets Class 1 eye-safety requirements for harmless measurement in public spaces, civil aviation and complex industrial settings.
02
12 km extreme reachRanges to 12000 m against large structures and natural terrain with accuracy of <±3 m RMS, setting a benchmark for civil very-long-range measurement.
03
High-gain, low-noise receiverA high-gain low-noise receiving circuit with adaptive optical noise suppression maintains signal-to-noise ratio and measurement stability at high amplification.
04
All-weather ruggednessStrong rejection of glare, smoke, rain and snow, with stable operation from −40 to +70 °C for demanding high-altitude and field conditions.
