Abstract
A depth information acquiring apparatus using a digital micro-mirror device (DMD), and a method thereof are provided. The depth information obtaining apparatus includes: a first digital micro-mirror device (DMD) that generates first line light and irradiates the first line light to an object; a second DMD that receives second line light reflected from the object and reflects light corresponding to the second line light; a sensor that senses light reflected by the second DMD; and a controller that controls operations of the first and second DMDs, and calculates depth information of the object by using information with respect to light sensed by the sensor.
