Abstract: Exemplary embodiments include a dual-mode optical device having an optical reflector, an optical transmitter, and a detector. The optical reflector is configured to reflect an incident first optical signal having a first wavelength, wherein the first optical signal includes a plurality of intermittent active and inactive durations. The optical transmitter is configured to emit a second optical signal having a second wavelength substantially similar to the first wavelength. The detector is configured to: determine the active and inactive durations of the first optical signal; and inhibit the optical transmitter from emitting the second optical signal during the detected active durations of the first optical signal.

Abstract: An apparatus comprises an input interface for receiving a color image of at least an object and a low resolution depth image of at least the object. The apparatus further comprises an image processing module configured to produce data for generating a three-dimensional color image based on a first color pixel image data of a first color pixel and a first derived depth pixel image data of a first derived depth pixel. The image processing module is configured to calculate the first derived depth pixel image data based on a measured depth pixel image data of a measured depth pixel and a weighting factor. The weighting factor is based on a color edge magnitude summation value of a path between the first color pixel and the reference color pixel. The apparatus further comprises an output interface for providing the generated three-dimensional color image.

Abstract: An oscillator driver system includes an oscillator structure and a driver circuit. The oscillator structure includes a rotor terminal configured to receive a rotor voltage and a stator terminal configured to receive a stator voltage, and is driven about a rotation axis according to a voltage difference between the rotor and stator voltages. The driver circuit is configured to generate a driving signal and output the driving signal as the rotor voltage, wherein the driving signal toggles between low and high voltage levels at an actuation frequency to drive the oscillator structure about the rotation axis, and wherein the stator voltage is a fixed voltage. The low and high voltage levels are greater than the stator voltage such that the voltage difference toggles between a low voltage difference and a high voltage difference as the driving signal toggles between the low voltage level and the high voltage level, respectively.

Abstract: A method of synchronizing a first oscillation about a first axis with a second oscillation about a second axis includes: generating a first position signal that indicates a position of the first oscillation about the first axis; generating a second position signal that indicates a position of the second oscillation about the first axis; determining a phase difference between the first and the second position signals; comparing the phase difference to a threshold value to generate a comparison result; generating a first reference signal having a first frequency and a second reference signal having a second frequency; synchronizing the first oscillation to the first frequency and synchronizing the second oscillation to the second frequency; monitoring the comparison result; and synchronously triggering a start of the first reference signal and the second reference signal responsive to the comparison result indicating that the phase difference is less than the threshold value.

Abstract: Exemplary embodiments include methods and/or procedures for receiving, in a time-multiplexed manner, a plurality of optical signals (e.g., infrared signals) having substantially similar wavelengths. These embodiments can include emitting a first optical signal having a first wavelength and comprising a plurality of intermittent active and inactive durations. These embodiments can also include receiving, during one or more of the active durations, a reflected version of the first optical signal and performing a time-of-flight measurement based on the first optical signal and the reflected version. These embodiments can also include receiving, only during one or more of the inactive durations of the first optical signal, a second optical signal having a second wavelength substantially similar to the first wavelength of the first optical signal. Exemplary embodiments also include optical sensing systems, optical devices, and optical systems comprising both, as well as methods for facilitating user interaction with an object.
