ACTIVE OPTICAL RADAR APPARATUS

摘要

PURPOSE: An active optical radar apparatus is provided to form focus of lights, reflected from objects in different distances, on light receiving surfaces in the same position of an optical detector by forming the same light path in a light-transmitting optical system and a light-receiving optical system. CONSTITUTION: An optical source unit(110) generates a set optical signal. A light-transmitting lens unit(120) emits the optical signal from the optical source unit into collimated light or angled light. A light scanning unit(130) scans the collimated light or angled light from the light-transmitting lens unit. A light-receiving lens unit(140) condenses optical signals reflected from an object(101). A wide band filter unit(150) passes a set bandwidth of the optical signal input from the light-receiving lens unit. An optical detector unit(160) changes the light condensed by the light-receiving lens unit into the electric signal. A signal processing unit(170) measures the time interval between the transmission and receiving of the optical signal or the intensity of the optical signal reflected from the object by processing the electric signal.
