Three-dimensional distance information acquisition device and electronic device including the same

A three-dimensional distance information acquisition device comprising:

• a transmitter configured to irradiate light to a scan area, scan the scan area in time division in a first direction, and irradiate light in at least one of a point unit or a line unit in a second direction orthogonal to the first direction;
• a receiver including a receiving optical system configured to have condensing power in the first direction greater than condensing power in the second direction, the receiving optical system configured to condense light reflected from the scan area and incident within a first range in the first direction, and the receiver including a photodetector having a light receiving area configured to detect the light condensed within the first range, and the photodetector configured to collect the light reflected from the scan area by using the receiving optical system and receive the light in at least one light receiving area in the first direction;
• and
• a controller configured to acquire three-dimensional distance information of the scan area from a detection signal of the photodetector by controlling the transmitter and the receiver.
