Abstract: A multi-channel SMI sensor includes an emitter configured to emit light having different polarizations and a polarization-selective lens for directing light having different polarizations towards different locations. The multi-channel SMI sensor is configured to measure physical phenomena at two different locations with a small footprint.

Abstract: An optical sensing system includes a transmitter side and a receiver side, and is configured to be positioned below a display of an electronic device. The transmitter side includes a light emitter. The receiver side includes an array of photodiodes. The light emitter of the transmitter side and the array of photodiodes of the receiver side are optically coupled via a waveguide. As a result of this construction, the optical sensing system can be operated as an interferometric optical sensor.
