Title:
SCANNING DEVICE AND DISTANCE MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/151092
Kind Code:
A1
Abstract:
Provided is a scanning device which can measure distance within a distance-measurement region by means of a scanning mode having a desirable density distribution locus. This scanning device has: an emission unit that emits light; an optical scanning unit that transmits the light towards a first region and a second region, which are adjacent to each other, by cyclically changing the transmission direction of the light; and an optical path control unit that guides a first scanning light to a first scanning region, said first scanning light having been transmitted from the optical scanning part towards the first region, and that guides a second scanning light to a second scanning region, said second scanning light having been transmitted towards the second region. The optical path control unit is configured so as to be able to change the positional relationship of the first scanning region and the second scanning region by changing the optical path of the first scanning light and the second scanning light.
