An off-axis optical combiner includes a parabolic lensing structure that selects collimated infrared image light received from an eyebox area for focusing to a focus of the off-axis optical combiner. Selecting the collimated infrared image light for focusing allows the parabolic lensing structure to form a same-sized image of an object having variable depth from the parabolic lensing structure.

A camera module, a camera assembly, and an electronic device are disclosed, which relate to the field of smart devices. The camera module includes a fixing member, a lens assembly, an image sensor, and a focusing assembly. The image sensor is configured to receive light transmitting through the lens assembly. In the focusing assembly, a first light-redirecting member is configured to redirect the light transmitting from the lens assembly to the image sensor; a second light-redirecting member is configured to redirect the light redirected by the first light-redirecting member, and configured to be movable relative to the fixing member to change a transmission distance of the light from the lens assembly to the image sensor.

There is provided a transparent screen which is capable of separating a direction where a hot spot is observed and a direction where a bright video is allowed to be observed, and establishing a direction where a video is allowed to be wholly brightly observed. A transparent screen includes a first transparent layer, a reflective layer reflecting projected video light, a second transparent layer disposed opposite to the first transparent layer with respect to the reflective layer so as to make a background visible therethrough; wherein the reflective layer has a plurality of slant reflective surfaces, each of the slant reflective surfaces being slant to a reference surface that is a surface of the first transparent layer opposite to the reflective layer; wherein each of the slant reflective surfaces is provided with a concavo-convex and is formed in a stripe shape when seen from a normal direction of the reference surface; and wherein the slant reflective surfaces are disposed so as to have angles to the reference surface, the angle changing with random variations in of range with respect to a certain central angle.

According to one embodiment, a light source includes a plurality of light-emitting elements each including one or more surface-emitting lasers; and a plurality of detecting elements located on a same substrate as the light-emitting elements. The detecting elements individually detect quantities of output light of the light-emitting elements.

Apparatus for heating a substrate within a substrate processing chamber are described herein. More specifically, possible lamp modules for use within a substrate processing chamber are described. The lamp modules include a reflector body. The reflector body is a reflective material. The reflector body includes grooves disposed in a surface and configured to direct radiant energy towards a substrate. Each ring includes multiple grooves with different cross sections to allow radiant energy to be directed at different radial positions on the substrate from the same ring. The grooves may be either curved or linear grooves.
