Abstract: An optical collimating unit is provided that comprises a laser unit, and a lens having three optical surfaces, being a first refractive surface, a second reflective surface and a third refractive surface. Also provided is a light projection device comprising an optical collimating unit that comprises a laser unit, a lens and an optical component configured to shape laser beams being emitted into respective desired light patterns.

Abstract: An optical module and a method for its used are provided. The optical module comprises: an image capturing device; an illuminating device; a position measurement unit and a processor configured to: a) identify objects included in at least one frame that has been captured by the image capturing device; b) determine expected position of the one or more identified objects based on data received from the position measurement unit; and c) control operation of the at least one illuminating device while capturing a new image, to illuminate only part of the field of view of the target being acquired by the at least one image capturing device, wherein the one or more identified objects are included.

Abstract: An image capturing arrangement is provided which comprises a depth (3D) sensor, a processor, an illuminating device and one or more image capturing devices. The depth sensor is configured to acquire at least a partial representation of the scene whose image is about to be taken, the processor retrieves required information from the acquired representation about distances of objects included in that scene from the sensor, and the illuminating device is configured to provide a non-uniform illumination of the scene whose image is to be captured, based on the retrieved information.

Abstract: A laser device comprising two lenses, each of which is configured to separately collimate radiant electromagnetic energy in a respective axis, wherein one of the two lenses is a fast-axis collimating (FAC) lens and the other of the two lenses is a slow axis collimating (SAC) lens, and wherein the SAC lens is characterized in that it has a first surface being a negative surface and a second surface being a positive surface.
