Detector Type

Note: Mechanical scanners offer 360° coverage but have moving parts. Solid-state LiDARs (MEMS, OPA, Flash) have no moving parts, enabling compact designs and higher reliability. FMCW LiDAR can measure velocity directly and has better interference immunity.

ToF Principle: Distance = (Speed of Light × Time) / 2 = (3×10⁸ m/s × t) / 2. For 200m range, round-trip time is ~1.33µs.

Interference Testing

Multi-LiDAR Interference: Test crosstalk between multiple LiDAR sensors. FMCW LiDAR has inherent immunity to interference. ToF LiDAR requires time-division or frequency-division multiplexing.
