An optical device may include an optic disposed in an optical path. The optical device may include a mount to dispose the optic in the optical path. The optical device may include a plurality of spring clamps to attach the optic to the mount. The spring clamp, of the plurality of spring clamps, may include a body, a spring, and a screw. The screw may be to attach to the mount and to compress the spring. The spring may be to dispose a leading edge of the body against the optic. The spring clamp may be to maintain the optic in the optical path for a thermal cycle of at least between approximately &#x2212;50&#xb0; C. and approximately 130&#xb0; C.

Spring clamp for optics

The use of one or more angled or curved and diverging light pipes or reflectors placed in a light source's, e.g. diode's, emission path at appropriate distances, angles and divergence, such that a diode's emission spot size is modified and or redirected from the diode's natural emission path to alternative planes at angle to the diode's natural emission path so that a diode emission safe spot size can be achieved on any plane at angle to the original diode natural emission path at minimum distances from the diode's point of emission.

Low profile depth camera

In order to maximize the dynamic range and depth of field for a depth camera used in a time of flight system, the light source is modulated at a plurality of different frequencies, a plurality of different peak optical powers, a plurality of integration subperiods, a plurality of lens foci, aperture and zoom settings during each camera frame time. The different sets of settings effectively create subrange volumes of interest within a larger aggregate volume of interest, each having their own frequency, peak optical power, lens aperture, lens zoom and lens focus products consistent with the distance, object reflectivity, object motion, field of view, etc. requirements of various ranging applications.

High dynamic range and depth of field depth camera

A time-of-flight (TOF) sensor pixel is provided that performs in-pixel subtraction. The TOF sensor pixel includes a photodetector, a capacitor, and circuitry. The photodetector detects light pulses emitted at a clock frequency, after a time of flight, to provide a photocurrent. The capacitor integrates the photocurrent over an integration period, while the circuitry reverses a flow direction of the photocurrent through the capacitor at twice the clock frequency. At the end of the integration period, the capacitor provides a differential photocharge, corresponding to a capacitor voltage. The capacitor voltage is related to the time of flight of the light pulses and may be used to determine a distance to a target.

Time-of-flight (TOF) system, sensor pixel, and method

A user interface apparatus and a method for adjusting the apparatus are disclosed. A position and/or a viewing angle of the user is tracked, and graphical interface objects are adjusted to keep them visible at different user's distances and viewing angles. For example, as the user steps away from the display, the objects on the display can be proportionally enlarged to make them appear of the same size to the user. The sensitivity of a gesture recognition system to the user's movements and gestures can be also adjusted to facilitate manipulation of the objects by the user at different distances from the display of the graphical user interface.
