Abstract: 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.

Abstract: PURPOSE: A dynamic range 3D image system is provided to obtain a dynamic range higher than the range when a 3D image is obtained. CONSTITUTION: An HDR(High Dynamic Range) generating module(440) generates a signal which shows the saturation degree of the pixel signal based on pixel signals detected by a pixel detecting module. The HDR generating module couples the pixel signals. The HDR generating module obtains a dynamic range image. A gain control signal generating module(430) outputs an output signal based on the size of a signal which shows the saturation degree of the pixel signal. The output signal is for supplying a voltage necessary for a gain control terminal of an optical detector.
