A display system can include a head-mounted display configured to project light to an eye of a user to display virtual image content at different amounts of divergence and collimation. The display system can include an inward-facing imaging system possibly comprising a plurality of cameras that image the user's eye and glints for thereon and processing electronics that are in communication with the inward-facing imaging system and that are configured to obtain an estimate of a center of rotation of the user's eye using cornea data derived from the glint images. The display system may render virtual image content with a render camera positioned at the determined position of the center of rotation of said eye.

A time of flight based depth detection system is disclosed that includes a projector configured to sequentially emit multiple complementary illumination patterns. A sensor of the depth detection system is configured to capture the light from the illumination patterns reflecting off objects within the sensor's field of view. The data captured by the sensor can be used to filter out erroneous readings caused by light reflecting off multiple surfaces prior to returning to the sensor.

Projector with spatial light modulation

An imaging system includes an illumination unit and a sensor unit disposed on a printed circuit board. The illumination unit includes a diode laser source inside an illumination housing. The sensor unit includes an image sensor having a pixel array and a lens barrel mounted on the image sensor with an adhesive, and an optical fiber coupled between the illumination housing and image sensor. The optical fiber is configured to collect a portion of light from the interior of the illumination housing that is emitted by the diode laser source and direct the portion of light to a corner of the pixel array of the image sensor that is located outside the lens barrel.

Global shutter pixel circuit and method for computer vision applications

A method for determining a distance to a target object includes transmitting light pulses to illuminate the target object and sensing, in a first region of a light-sensitive pixel array, light provided from an optical feedback device that receives a portion of the transmitted light pulses. The feedback optical device includes a preset reference depth. The method includes calibrating time-of-flight (TOF) depth measurement reference information based on the sensed light in the first region of the pixel array. The method further includes sensing, in a second region of the light-sensitive pixel array, light reflected from the target object from the transmitted light pulses. The distance of the target object is determined based on the sensed reflected light and the calibrated TOF measurement reference information.

Real time calibration for time-of-flight depth measurement

An image sensor device includes a plurality of pixel cells arranged in a pixel array, a control circuit for controlling an exposure phase and a sampling phase of the image sensor device. Each of the plurality of pixel cells includes a photodiode, a storage diode, and a floating diffusion region. The control circuit is configured to activate the photodiode in a plurality of time windows to sense light reflected from a target as a result of a corresponding plurality of emitted light pulses, with a pre-determined delay time between each time window and a corresponding emitted light pulse. The photodiode can be activated using a plurality of bias voltage pulses or a plurality of global shutter signal pulses.

An imaging lens includes one or more lens elements configured to receive and focus light in a first wavelength range reflected off of one or more first objects onto an image plane, and to receive and focus light in a second wavelength range reflected off of one or more second objects onto the image plane. The imaging lens further includes an aperture stop and a filter positioned at the aperture stop. The filter includes a central region and an outer region surrounding the central region. The central region of the filter is characterized by a first transmission band in the first wavelength range and a second transmission band in the second wavelength range. The outer region of the filter is characterized by a third transmission band in the first wavelength range and substantially low transmittance values in the second wavelength range.

Method and system for multiple f-number lens

An eye movement tracking device that can be mounted to standard eyeglasses as disclosed. The device comprises an illumination source, a time-of-flight (TOF) camera and a processor. The source transmits energy within a frequency band from a location proximate to an eye of a person, such that at least a first portion of the transmitted energy is reflected off a lens of eyewear worn by the person to subsequently reflect off the eye, and such that at least a second portion of the transmitted energy is transmitted through the lens to reflect off objects in the person's environment. The TOF camera detects reflections of at least the first portion of the transmitted energy, and distinguishes them from other energy detected by the TOF camera in said frequency band, based on TOF principles. The processor uses the detected reflections of the first portion of the transmitted energy to determine eye position.

Eyewear-mountable eye tracking device

A pixel cell for differential light sensing includes a plurality of photodiodes and a corresponding plurality of storage diodes. Each storage diode is disposed between a first adjacent photodiode and a second adjacent photodiode, and each storage diode is configured to receive photo charges from either or both of the first adjacent photodiode and the second adjacent photodiode. Each photodiode is disposed between a first adjacent storage diode and a second adjacent storage diode, and each photodiode is configured to transfer photo charges to either or both of the first adjacent storage diode and the second adjacent storage diode.
