Abstract
A distance measuring device includes a laser light source, an irradiation optical system comprising a beam spreader which is configured to spread the laser light about a first optical axis, a light reception optical system having a second optical axis different from the first optical axis and positioned to receive reflected light of the laser light from the object for measuring a distance to the object, a sensor with light receiving elements arranged in a first direction, the sensor being positioned to receive light reflected from the object which has passed through the light reception optical system, and a distance measuring unit configured to acquire distance information relating to the object based on the difference in time between emission of the laser light source and the reception of the reflected light at each of the plurality of light receiving elements.
