Title:
LASER RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/130729
Kind Code:
A1
Abstract:
A laser light source that outputs laser light is arranged in a light source substrate (10). An emission lens (20) smooths and outputs laser light output by the laser light source. A scanning mirror (41) reflects laser light output from the emission lens, emits said laser light to outside a case, and can change orientation relative to the laser light source. A scanning substrate (44) controls the orientation of the scanning mirror relative to the laser light source. A light-receiving substrate (70) has a light-receiving element provided therein that receives reflected light being laser light that has been reflected by a target. A light-receiving lens (60) condenses the reflected light on to the light-receiving element. The case houses the light source substrate, the emission lens, the scanning mirror, the scanning substrate, the light-receiving substrate, and the light-receiving lens. The light-source substrate, the scanning substrate, and the light-receiving substrate are arranged at positions that do not overlap in the depth direction of the case and an innermost member is also arranged in the case, said innermost member being the member among the emission lens, the scanning mirror, and the light-receiving lens that has an end section thereof on the innermost side of the case in the depth direction.
