Abstract
A light range finding apparatus is provided with a light emitting optical system that projects a pattern light having an irradiation region and a non-irradiation region; a light receiving sensor including an arrayed light receiving element; a light receiving optical system that receives a reflected light of the pattern light and enlarges a portion of the reflected light corresponding to the irradiation region to be larger than a single light receiving element and causes the enlarged reflected light to be incident on the light receiving sensor; a distance measurement unit that measures a distance to the object based on an output of the light receiving sensor; and a positional alignment section that performs, based on the output of the light receiving sensor, a positional alignment of at least a part of the light emitting optical system and the light receiving optical system.
