Abstract

A light-based detection and ranging (LiDAR) system may include a sealed container having a transparent window in a sidewall thereof. The sealed container may include a polygonal reflector therein, at a location adjacent the transparent window. An optically transparent fluid having a refractive index greater than 1.3, may be provided which surrounds the polygonal reflector within the container and extends between the polygonal reflector and the transparent window. The polygonal reflector and the optically transparent fluid may be configured to be neutrally buoyant relative to each other within the sealed container.
