摘要： An optical package may include a fan-out-wafer-level-packaging (FOWLP) sub-package including a redistribution layer (RDL) on a molded component including an electrical chip. The optical package may include an optical chip over the FOWLP sub-package. The optical chip may be electrically connected to the RDL. An area of a surface of the RDL may be larger than an area of a surface of the optical chip. The optical package may include a package housing over the optical chip such that light to be received or transmitted by the optical chip may is to pass through the package housing.

摘要： In some implementations, a light detection and ranging (LIDAR) system includes a vertical cavity surface emitting laser (VCSEL) array including a plurality of VCSELs. The VCSEL array may have a first aspect ratio. The LIDAR system may include a set of transmission optics configured to receive light from the VCSEL array and to illuminate a field of view having a second aspect ratio that is greater than the first aspect ratio. The LIDAR system may include an image sensor array configured for line readout. The image sensor array may have a third aspect ratio that is different from the first aspect ratio. The LIDAR system may include a set of reception optics configured to image light reflected from objects in the field of view, having the second aspect ratio, onto the image sensor array having the third aspect ratio.

摘要： An optical device may include emitter array to emit light. The optical device may include a collimating element to create an image of the light emitted by the emitter array. The optical device may include a diffractive optical element (DOE) to generate a pattern from the image of the light. The optical device may include a distortion correction element to reduce distortion in the pattern on a screen or to shape the pattern on the screen.

摘要： In some implementations, a dot projector optic may include a collimating lens; a fisheye lens; and a dot aberration correction element disposed between the collimating lens and the fisheye lens. An input to the fisheye lens, from the dot aberration correction element, may be associated with a first field of view angle. An output from the fisheye lens may be associated with a second field of view angle that is larger than the first field of view angle.
