The invention provides a photoreceptor, a flight time measuring device, and an optical radar. The photoreceptor can realize a light receiving area suitable for an irradiation area of pulsed light andcan greatly reduce positioning accuracy of the photoreceptor relative to a light emitting element, thereby realizing a flight time measuring device which does not reduce the maximum measuring distanceand can reduce cost, and realizing an inexpensive optical radar which increases the maximum measuring distance. The photoreceptor (80) measures the flight time by imaging the reflected light from anirradiation region that receives irradiation of an object irradiated with pulsed light by a lens and receiving the imaged light by a light receiving unit (81). The light receiving unit (81) is formedto be larger than a projection unit (PA) that is reflected by an irradiation region of the object and forms an image. A portion of the photoreceptor (81) that overlaps the projection unit (PA) is activated as the light receiving area.

A quantum-illumination receiver is described comprising a phase-conjugation and mixing system for mixing and / or conjugating the idler beam from an entangled light transmitter and the return beam from the target to produce an output beam that is representative of the presence or absence of the target, a light beam collector for receiving a return light beam from the target region and directing the return light beam from a target region to the phase-conjugation and mixing system input, an optical input for receiving an idler light beam from a transmitter and directing the idler light beam from the transmitter to the phase-conjugation and mixing system, a sensor for measuring the output of the phase-conjugation and mixing system, and a processor to process the output of the sensor to make an determination about the presence of the target.

A system and method for measuring depth using an optical radar system are described. The system includes an optical radar, a camera, a display, and a processor. The optical radar emits a signal towards an object. The processor identifies an object depicted in an image captured with the camera. The processor generates the signal with a non-repeating pattern of amplitude and frequency, and computes a depth of the object based on a difference in phase angle between the signal emitted from the optical radar and a return signal received at the optical radar. The depth includes a distance between the optical radar and the object. The processor generates AR content based on the identified object and adjusts a characteristic of the AR content in the display based on the computed depth of the object.
