Distance measuring apparatus which detects optical system abnormality
A distance measuring apparatus includes an optical system abnormality detection section for detecting abnormalities of an optical system of the distance measuring apparatus by comparing a relationship between a measured distance value d and a light intensity Ls with a reference value K.sub.ρ, K.sub.ρ1, K.sub.Ls0d0, or K.sub.Ab0.
Beam homogenization for occlusion resistance
Example embodiments relate to beam homogenization for occlusion avoidance. One embodiment includes a light detection and ranging (LIDAR) device. The LIDAR device includes a transmitter and a receiver. The transmitter includes a light emitter. The light emitter emits light that diverges along a fast-axis and a slow-axis. The transmitter also includes a fast-axis collimation (FAC) lens optically coupled to the light emitter. The FAC lens is configured to receive light emitted by the light emitter and reduce a divergence of the received light along the fast-axis of the light emitter to provide reduced-divergence light. The transmitter further includes a transmit lens optically coupled to the FAC lens. The transmit lens is configured to receive the reduced-divergence light from the FAC lens and provide transmit light. The FAC lens is positioned relative to the light emitter such that the reduced-divergence light is expanded at the transmit lens.
