The apparatus for obtaining an image includes a light source, a scanner, a first beam splitter, and a light receiving unit. The light source generates a laser pulse. The scanner irradiates the laser pulse in a first direction. The first beam splitter splits the laser pulse irradiated in the first direction in the first direction and a second direction and irradiates the split laser pulse. The light receiving unit detects reflected light. Accordingly, it is possible to irradiate light to a wide range by a light source having a relatively small divergent angle.Type: ApplicationFiled: February 12, 2015Publication date: December 31, 2015Applicant: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Jung Ho SONG, Myoung Sook OH, Ki Soo KIM, Bong Ki MHEEN, Jae Sik SIM, Yong Hwan KWON, Min Hyup SONG, Gyu Dong CHOI
