Abstract: A meta projector includes an edge emitting device configured to emit light through a side surface thereof, a meta-structure layer spaced apart from the upper surface of the edge emitting device that includes a plurality of nanostructures having a sub-wavelength shape dimension smaller than a wavelength of the light emitted from the edge emitting device, and a path changing member configured to change a path of the light emitted from the edge emitting device so as to direct the path toward the meta-structure layer. The meta projector may thus be configured to emit a light pattern of structured light, based on directing the light emitted from the edge emitting device through the meta-structure layer, while having a relatively compact device size.

Abstract: A three-dimensional (3D) image sensor device and an electronic apparatus including the 3D image sensor device are provided. The 3D image sensor device includes: a shutter driver that generates a driving voltage of a sine wave biased with a first bias voltage, from a loss-compensated recycling energy; an optical shutter that varies transmittance of reflective light reflected from a subject, according to the driving voltage, and modulates the reflective light to generate at least two optical modulation signals having different phases; and an image generator that generates 3D image data for the subject which includes depth information calculated based on a phase difference between the at least two optical modulation signals.

Abstract: A three-dimensional (3D) image sensor module including: an oscillator configured to output a distortion-compensated oscillation frequency as a driving voltage of a sine wave biased with a bias voltage; an optical shutter configured to vary transmittance of reflective light reflected from a subject, according to the driving voltage, and to modulate the reflective light into at least two optical modulation signals having different phases; and an image generator configured to generate image data about the subject, the image data including depth information that is calculated based on a difference between the phases of the at least two optical modulation signals.
