Abstract: 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 −50° C. and approximately 130° C.

Abstract: 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.

Abstract: 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.
