Abstract: An image capture apparatus with an image sensor and lens assembly (ISLA). The ISLA includes an image sensor, a lens mount, a lens barrel, and a lens sub-barrel. A lens mount connects the ISLA within the image capture apparatus. The lens mount extends away from the image sensor. The lens barrel is in communication with the lens mount. Barrel lenses are located within the lens barrel. The lens sub-barrel is movably connected to the lens barrel, the lens mount, or both. A sub-barrel lens is located within the lens sub-barrel.

Abstract: A LiDAR system includes an optical source to emit an optical beam toward a target, a partially reflective surface to generate a local oscillator (LO) signal from the optical beam, and an optical lens disposed in front of a photodetector (PD), wherein the LO signal is incident at a decenter of the optical lens to shift the LO signal at the photodetector with respect to a return signal received from the target.

Abstract: A method of aligning an optical lens in a LiDAR system includes emitting an optical beam by an optical source. The method includes placing the optical lens in front of a photodetector at a first predetermined position. The method further includes moving the optical lens to a plurality of Z-positions along a direction of an optical axis, the plurality of Z-positions corresponding to a plurality of parameter values of the LO signal. The method further includes generating a fitting function based on a set of values of the LO signal; and determining a parameter value of the LO signal for each Z-position. The method includes determining an initial Z-axis position of the optical lens by selecting a Z-position from the plurality of Z-positions based on a plurality of parameter values. The method includes determining a final Z-position of the optical lens by adding an offset to the initial Z-axis position.

Abstract: A LiDAR system includes an optical subsystem with an optical axis. The optical subsystem includes an optical source to emit an optical beam, a first optical lens to transmit the optical beam, an optical window to reflect a first portion of the optical beam to generate a LO signal, an optical scanner to transmit a second portion of the optical beam to a target to scan the target to generate a target return signal, where the LO signal is disposed to be decentered from the optical axis on a second optical lens in front of a photodetector (PD) to increase a percentage of an overlap of the LO signal and the target return signal on the PD.
