A sensor includes a sensor array. The sensor array includes a plurality of passive imaging pixels and a plurality of time of flight (TOF) imaging pixels. A method of imaging includes collecting passive imaging data from a sensor array and collecting time of flight (TOF) imaging data from the sensor array. Collecting passive imaging data and collecting TOF imaging data can be performed at least partially at the same time and along a single optical axis without parallax.

Sensors for simultaneous passive imaging and range finding

A pixel includes a constant current source electrically connected to a first node. An integrating capacitor is electrically connected between the first node and a ground. A sampling transistor is electrically connected between the first node and a second node. A photodiode is electrically connected between a base terminal of the sampling transistor and the ground for switching electrical connectivity through the sampling transistor in response to radiation incident on the photodiode.

Pixels for time of flight (TOF) imaging

An imaging system includes an imager housing having a primary aperture defining an optical axis. A primary lens is disposed over the primary aperture. A first focal plane array (FPA) is within the imager housing. A second FPA is within the imager housing. A digital micro-mirror device (DMD) is angled with respect to the optical axis and optically coupled to the primary lens to selectively reflect light entering the primary aperture to at least one of the first FPA or the second FPA.

Imaging systems with digital micromirror devices (DMD)

An optical device is disclosed. The optical device may generate light for projection into a user's eye. The optical device may have a switch connected to an eyecup. When the eyecup is pressed against the user's face, the switch may be actuated, signaling the optical device to generate light for projection into a user's eye. When the eyecup is not pressed against the user's face, the switch may be unactuated, signaling the optical device to cease to generate light for projection into a user's eye. Various electronics of the optical device may remain active, for example, a controller may continue to generate an image for representation by the generated light, but the optical device may refrain from generating the light, such as by a display. In this manner, inadvertent light leakage may be ameliorated, and power consumption by the optical device lessened when the eyecup is not depressed.
