Abstract
A depth image measuring camera includes an illumination device configured to irradiate an object with light, and a light-modulating optical system configured to receive the light reflected from the object. The depth image measuring camera includes an image sensor configured to generate an image of the object by receiving light incident on the image sensor that passes through the light-modulating optical system. The light-modulating optical system includes a plurality of lenses having a same optical axis, and an optical modulator configured to operate in two modes for measuring a depth of the object.
