The light sensing element is disposed on the base. The image capturing lens is disposed above the light sensing element. The light source is disposed on the base, beside the light sensing element, and configured to emit a light beam. The top cover covers the light source and has a slit pattern. The slit pattern includes at least one slit. The slit pattern is disposed on a path of the light beam to diffract the light beam. The image capturing lens is configured to collect a signal light formed by an outside object reflecting a diffracted light beam and transmit the signal light to the light sensing element.

A driver monitoring system module comprises a housing, a first circuit board, and a second circuit board. The first circuit board is generally mounted at a first location within the housing. The second circuit board is generally mounted at a second location on an exterior surface of the housing. The first circuit board and the second circuit board are partially overlapped in a first direction and separated by a predefined distance in a second direction. The exterior surface of the housing generally defines a passage between overlapped portions of the first circuit board and the second circuit board that allows ambient air to pass between the first circuit board and the second circuit board to provide convective cooling.

An extended Reality (XR) system provides methodologies for capturing hand poses being made by a user in low-light environments. The XR system capture, using one or more visible light cameras, tracking video frame data of a hand pose of a user of the XR system. The XR system generates hand-tracking data based on the tracking video frame data. The hand-tracking data includes a skeletal model and a hand-tracking confidence level indicating a probability that the skeletal model matches the hand pose. The XR system compares the hand-tracking confidence level to a threshold confidence value, and based on determining the first hand-tracking confidence level is below the threshold confidence value, activates one or more wide-spectrum cameras to capture subsequent tracking video frame data of the hand pose. The XR system may also activate an IR light emitter to illuminate the hands of the user.

An optical subsystem of a near-eye display system provides for projecting light of a virtual image of image content to an eye location, and provides for collecting light of the virtual image onto an exit pupil on a surface proximate to an outer surface of an eye when at the eye location. A subpupil modulator within an aperture in cooperation with the optical subsystem provides for forming a plurality of subpupils within the exit pupil, provides for less than all of the light of the virtual image associated with one or more less than all of the plurality of subpupils to be projected to the eye location, and provides for individually and independently controlling an intensity of the light through each activated subpupil to a level less than a maximum level of intensity.

A method of controlling exposure time is disclosed comprising receiving an image of an eye from an image sensor, the image resulting from the image sensor detecting light during a first exposure time. A pupil intensity is determined as an intensity of a representation of a pupil of the eye in the image and an iris intensity is determined as an intensity of a representation of an iris of the eye in the image. Furthermore, a pupil-iris contrast is determined as a contrast between the representation of the pupil in the image and the representation of the iris in the image. On a condition that the pupil intensity is determined to meet an intensity condition, an intensity compensated exposure time is determined which is different from the first exposure time, and on a condition that the pupil-iris contrast is determined to meet a contrast condition, a contrast compensated exposure time is determined which is different from the first exposure time. Furthermore, a second exposure time is set based on any determined intensity compensated exposure time and any determined contrast compensated exposure time.
