Lake Fusion commits to MicroVision lidar for helicopter obstacle detection

Lake Fusion Technologies has agreed to buy MicroVision's IRIS lidar sensors during 2027 and into 2028 for its AS-1 helicopter awareness system, moving the companies' earlier integration work into a commercial supply commitment. Purchase volumes and financial terms were not included in the announcement. ^[1]

AS-1 combines two IRIS sensors mounted in the helicopter's nose with software that brings their measurements together. It is designed to warn crews about obstacles during operations close to the ground, including landings away from established airfields, hovering and search-and-rescue work. Thin wires and power lines are among the hazards the companies identify. ^[1]

IRIS combines a 1550 nm laser and an InGaAs receiver with a field of view of 120° horizontally and 26° vertically, according to its product sheet. The frame rate is configurable between 1 Hz and 30 Hz. Its quoted maximum instrumented range is 280 metres, which describes the sensor's measurement envelope rather than guaranteeing detection of every obstacle at that distance. ^[2] MicroVision specifies range precision of 4 cm at 50 metres for a target with 10% reflectivity. That attached condition is useful when assessing a sensor whose intended targets can range from substantial structures to small objects offering much less reflected light. The company also lists a Class 1 laser classification under IEC/EN 60825-1 and IP67 protection for the sensor. ^[2]

MicroVision's airborne perception offering uses lidar data to build a 3D view around an aircraft, supporting obstacle awareness in conditions where a camera image alone may be difficult to interpret. Turning those measurements into a warning also involves the perception software and its integration with the aircraft's awareness system. ^[3]

Following the partners' June 2026 work on IRIS integration, the new agreement establishes a framework covering development, certification, supply and subsequent support for civil and military helicopter applications. Certification remains part of that programme; the announcement does not establish that the combined system has completed it. ^[1]

The initial focus is airborne use, with the partners also intending to investigate further defence, safety and security applications. ^[1]
