Structured-light projector and electronic apparatus including structured-light projector

An electronic apparatus comprising:

• a structured-light projector configured to generate structured light to an object;
• a sensor configured to receive light reflected from the object;
• and
• a processor configured to obtain shape information of the object based on the light received from the sensor,
• wherein the structured-light projector comprises:
• an illuminating device configured to emit illumination light;
• a pattern mask configured to partially transmit the illumination light to generate structured light;
• and
• a lens configured to transmit the structured light,
• wherein the pattern mask comprises:
• a light-transmitting slit configured to transmit the illumination light, and
• a plurality of reflection patterns configured to obliquely reflect the illumination light toward the light-transmitting slit.
