摘要： Technology for detecting a change in a configuration position of one or more elements in an illumination system is described. A light source generates an illumination signal, and an element of the system directs a portion of the light of the signal back to a light detector. In one example, the portion of light is reflected back to the light detector. By monitoring an output signal of the light detector based on the directed light, control circuitry can detect that a position of an element of the system has changed. In one example, an off-the-shelf integrated circuit laser diode package including a monitor photodiode can be used with a reflective element. In one example, the reflective element is a tilted optical element. Changes can be detected in the configuration of one or more optical elements of the illumination system which are outside the laser diode package.

摘要： A projector is disclosed for use in a 3-D imaging device. The projector includes a light source formed of a vertical-cavity surface-emitting laser, or VCSEL array. The VCSEL array provides a light source for illuminating a capture area. Light from the VCSEL array is reflected off of objects in the capture area and received within a sensing device such as a 3-D camera. The projector may further include a collimating lens array for focusing the light emitted from each VCSEL in the array, as well as a DOE for patterning the light from the collimating lens array to enable the sensing device to generate a 3-D image of the objects in the capture area.

摘要： A 3-D depth camera system, such as in a motion capture system, tracks an object such as a human in a field of view using an illuminator, where the field of view is illuminated using multiple diffracted beams. An image sensing component obtains an image of the object using a phase mask according to a double-helix point spread function, and determines a depth of each portion of the image based on a relative rotation of dots of light of the double-helix point spread function. In another aspect, dual image sensors are used to obtain a reference image and a phase-encoded image. A relative rotation of features in the images can be correlated with a depth. Depth information can be obtained using an optical transfer function of a point spread function of the reference image.

摘要： Various embodiments are disclosed for setting a depth camera light source operating temperature in a thermal tuning mode executed during a depth camera manufacturing process. One embodiment of a method includes illuminating a target with light from a light source at a plurality of light source temperatures; for each light source temperature, sensing an intensity of reflected light received at a light sensor through a light filter positioned intermediate the target and the light sensor; approximating a frequency response relationship between a light filter cutoff frequency and a light source emission wavelength based on a comparison of the sensed intensities and stored reference data; generating a temperature set point so that the light source emission wavelength does not overlap the light filter cutoff frequency by more than a predetermined overlap threshold; and programming a temperature controller to control the light source to the temperature set point during depth camera operation.

摘要： Embodiments related to the enhancement of contrast in an image pattern in a structured light depth sensor are disclosed. For example, one disclosed embodiment provides, in a structured light depth sensor system comprising a structured light depth sensor, a method comprising projecting a light pattern onto an object, detecting via an image sensor an image of the light pattern as reflected from the object, increasing a contrast of the light pattern relative to ambient light present in the image of the light pattern as reflected from the object to form a contrast-enhanced image of the light pattern as reflected from the object, and based upon a motion of the object as detected via the contrast-enhanced image of the light pattern, controlling an application that is providing output to a display.

摘要： The technology provides decoupling an aspheric optical element from a birdbath optical element in a near-eye display (NED) device. One or more aspheric lens are used with a spherical birdbath reflective mirror in a projection light engine of a NED device. A projection light engine provides image light (or other information), by way of the spherical birdbath reflective mirror and at least one aspheric lens, to a near-eye display of the NED device. The spherical birdbath reflective mirror collimates and reflects the image light to an exit pupil external to the projection light engine. Decoupling the aspheric optical element from the spherical birdbath reflective mirror may enable high modulation transfer function (MTF) and improved manufacturability of the projection light engine. The NED device having aspheric optical elements decoupled from a birdbath optical element may be positioned by a support structure in a head-mounted display (HMD) or head-up display (HUD).
