OBSTACLE DETECTOR FOR VEHICLE

摘要

PURPOSE:To narrow the dead angle area at which no laser light will hit an obstacle by additionally emanating a laser light with a large angle of emanation thereto enough to overlap the emission area of a laser with a specified angle of emanation. CONSTITUTION:An obstacle is irradiated with a laser light from long-range optical systems 200 and 300 with a specified angle of emanation. In addition, it is irradiated with a laser light with a large angle of emanation enough to overlap the emission area of the laser light from a short-range optical system 400. With such an arrangement, laser light is irradiated on a short-range obstacle to narrow the dead angle area at which no laser light will hit the obstacle.
