Patent number: 11916356Abstract: An emitter array, may comprise a first set of emitters that has a nominal optical output power at an operating voltage. The emitter array may comprise a second set of emitters that has substantially less than the nominal optical output power or no optical output power at the operating voltage. The first set of emitters and the second set of emitters may be interleaved with each other to form a two-dimensional regular pattern of emitters that emits a random pattern of light at the nominal optical output power at the operating voltage. The first set of emitters and the second set of emitters may be electrically connected in parallel.Type: GrantFiled: May 6, 2022Date of Patent: February 27, 2024Assignee: Lumentum Operations LLCInventors: Vincent V.

Patent number: 11742630Abstract: A structured light system may include a semiconductor laser to emit light and a diffractive optical element to diffract the light such that one or more diffracted orders of the light, associated with forming a structured light pattern, are transmitted by the diffractive optical element. The diffractive optical element may be arranged such that the light is to be incident on the diffractive optical element at a substantially non-normal angle of incidence. The substantially non-normal angle of incidence may be designed to cause the diffractive optical element to transmit a zero-order beam of the light outside of a field of view associated with the diffractive optical element.Type: GrantFiled: September 3, 2021Date of Patent: August 29, 2023Assignee: Lumentum Operations LLCInventors: Vincent V.

Patent number: 9019480Abstract: 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.Type: GrantFiled: February 26, 2013Date of Patent: April 28, 2015Assignee: JDS Uniphase CorporationInventors: An-Chun Tien, Lucas Morales, Vincent V.
