Title:
EMISSION DEVICE
Document Type and Number:
Japanese Patent JP2023075332
Kind Code:
A
Abstract:
To provide an emission device and the like that improve detection accuracy of, for example, vehicles.SOLUTION: A laser inter-vehicle range-finder is mounted to an own vehicle. The laser inter-vehicle range-finder is configured to emit light in an emission direction that is forward or backward; detect other vehicle located in the emission direction. The laser inter-vehicle range-finder comprises an emission unit. The emission unit is configured to have a directional characteristic in which the light is emitted with the light converged to an emission area 40 serving as an area where the light is emitted. The emission area 40 is shaped in which a width of a first portion 401 corresponding to the other vehicle present at a distant location serving as a distant location is smaller than a width in a left/right direction of a second portion 402 corresponding to the other vehicle present at a close location further than the distant location, and on a lower side further than the first portion 401.SELECTED DRAWING: Figure 5
