Provided are methods for verifying the performance of an image sensor mounted to a vehicle, which can include causing alignment of a collimator with an image sensor mounted to a vehicle, receiving sensor data associated with the image sensor based at least in part on causing the alignment of the collimator with the image sensor, determining that the sensor data does not satisfy a performance specification associated with the image sensor, determining an image sensor alert associated with the image sensor based at least in part on determining that the sensor data does not satisfy the performance specification associated with the image sensor, and routing the image sensor alert.

A laser processing head directs laser energy along an optical axis from a fiber to perform brazing or welding operations. A collimating stage collimates a diverging beam of the laser energy from the fiber into a collimated beam, and a focusing stage focuses the collimated beam into a converging beam to a focus spot for the desired operation. At least one of the stages has a changeable effective focal length for zoom functionality. A freeform refractive optic can be positioned in at least one of the diverging and collimated beams. For example, a freeform refractive optic in a first position is placed out of the diverging beam. However, the freeform refractive optic in a second position placed in the diverging beam can field map or intensity map the diverging beam to produce the mapped diverging beam, which increases an image of the fiber tip to the collimating stage.

An image projector includes a spatial light modulator (SLM) with a two dimensional array of pixel elements controllable to modulate a property of light transmitted or reflected by the pixel elements. An illumination arrangement delivers illumination to the SLM. A collimating arrangement collimates illumination from the SLM to generate a collimated image directed to an exit stop. The illumination arrangement is configured to sequentially illuminate regions of the SLM, each corresponding to a multiple pixel elements. A controller synchronously controls the pixel elements and the illumination arrangement so as to project a collimated image with pixel intensities corresponding to a digital image.

The present disclosure provides a laser projection component and a detection method thereof, and an electronic device. The laser projection component is applicable to the depth camera component and is configured to project a laser pattern. The detection method includes: obtaining the laser pattern; determining whether a preset identifier exists in the laser pattern; and determining that the depth camera component is abnormal when the preset identifier does not exist in the laser pattern.

The present disclosure provides systems and methods for preventing or minimizing optical crosstalk in an optical circuit switch (“OCS”). The OCS may include a collimator lens assembly. The collimator lens assembly may include a lens array defined by a plurality of ports. Each port may include a lenslet and a spacer paired with each lenslet. Crosstalk may occur when light from other ports enter the target port's optical fiber. The collimator lens assembly may include an insert positioned relative to the lenslet. The insert may define an aperture that allows light from the target port to pass through. The insert may prevent a portion of light from adjacent ports from passing through the aperture. The insert may be located between the lenslet and spacer, on the curved surface of the lenslet, or on a plate located at a distance from the front of the lenslet.
