Embodiments of the disclosure provide a transmitter containing a Risley prism-based scanning mechanism, an optical sensing system containing the same, and an optical sensing method using the same. For example, the optical sensing system includes a laser emitter configured to sequentially emit a series of optical signals. The optical sensing system further includes a plurality of prisms configured to receive the series of optical signals and sequentially direct the series of optical signals at different directions in an angle of view of the optical sensing system. At least one prism of the plurality of prisms is configured to rotate relative to at least one other prism of the plurality of prisms to refract the optical signals towards the respective different directions.

A compact projector for use in a head-mounted display device consists of an illumination section, a relay section, and a numerical aperture expander (NAE). The illumination section includes one or more illumination sources, a scanner, and a focusing lens which converges light onto an image plane. The NAE receives light from the illumination section, expands the average numerical aperture of the light, and transmits the light to the relay section. The relay section includes optical elements which collimate light from the image plane onto an exit pupil. The projector may also be fitted with lateral-axis and/or vertical-axis stops which prevent stray light from passing through the exit pupil.

An optical sensing device includes a planar substrate and an array of optical transceivers disposed on the planar substrate. Each optical transceiver includes a photodetector, at least one turning mirror having a reflective surface disposed diagonally relative to the substrate, and multiple waveguides disposed parallel to the substrate. The waveguides include a transmit waveguide, which is coupled to convey outgoing light from a coherent light source to the at least one turning mirror for output from the optical transceiver, and a receive waveguide, which is coupled to receive incoming light reflected by the at least one turning mirror and to convey the incoming light to the photodetector.

An apparatus includes an aperture disposed through an outer layer, a folding prism adjacent to the aperture, and a multi-mode optical fiber on which the folding prism is disposed.
