Abstract: A method of spectral beam-combining an array of fiber optics is disclosed. Each fiber may be coupled to a high-power, wavelength-stabilized, fiber-coupled, diode-laser module and has a fiber-by-fiber pre-selected wavelength. The wavelengths may be chosen such that the array can be spectrally combined on, for example a transmission grating and re-focused into an output fiber. This approach is scalable to, for example, 10 kW power and have a beam quality sufficient for metal cutting applications.

Abstract: An apparatus installed in a head-mounted display (HMD) has a coupling prism formed by packing diagonally-reflective (DR) prisms together. Each DR prism has an internal diagonal plane that is at least partially reflective. A captured image of eye or environmental scene received by a DR prism is reflected to an image-leaving end surface thereof. Image-leaving end surfaces of all DR prisms are oriented along a same direction to optically multiplex the captured images to create a multi-channel image. An imaging sensor on the coupling prism images the multi-channel image, avoiding inter-channel interference caused by spillover of captured-image signals while allowing one imaging sensor instead of multiple ones to image the captured images. A micro display displays a visible image to one DR prism, whose internal diagonal plane reflects the visible image along a direction towards an eye. Hence, the apparatus also enables image displaying to a HMD wearer.
