Embodiment Construction

[0043] To address the challenge of combining a large number of laser beams, and the need to do so using a structure that is easy to manufacture and scalable, the present specification provides an apparatus 100 for combining light as figure 1 shown. The device 100 includes a support 105 having a first surface 110 and a second surface 115 opposite the first surface 110 . The support member 105 also defines a support hole 155 extending through the first surface 110 and the second surface 115 . In the device 100 , the support 105 is shaped like a disc, and the support hole 155 is shaped as a circular hole concentric or substantially concentric with the disc of the support 105 . The support 105 may also be described as a circular plate and / or a circular sheet.

[0044] The device 100 also includes a receiving bank 120 disposed and fixed on the first surface 110 . Receiving group 120 is configured to receive a first group of light sources, such as light source 125 . The light so...

Abstract

There is provided an apparatus for combining light, which comprises a first face, a second face, and a support aperture extending through the two faces. The apparatus also comprises a first receivingbank and a second receiving bank disposed on the first face and second face respectively, and configured to receive first and second sets of light sources configured to emit first and second sets of light beams respectively. The apparatus also comprises a first reflector defining a reflector aperture and configured to reflect the first set of light beams towards the support aperture, and a secondreflector configured to reflect the second set of light beams towards the support aperture. Moreover, the apparatus comprises a differential reflector disposed in the support aperture and configured to reflect the first set of light beams and transmit the second set of light beams.

Description

technical field [0001] This description relates to a device for combining light beams, in particular to a device for combining light beams using curved mirrors. Background technique [0002] Among other things, laser light sources are used in image projection due to their narrow emission spectrum. Laser light can be produced by a variety of different light sources, including solid-state sources such as laser diodes. In image projection applications, it is often necessary to combine laser beams from a large number of laser diodes to form a combined beam, which is then used for image projection. Traditionally, it has been customary to combine such a large number of laser beams with a large array of small folding mirrors. Fabricating and calibrating these arrays of folded mirrors can be challenging. Furthermore, such folding mirrors cannot easily accommodate an increase in the number of light sources without the need to construct and / or add additional folding mirrors. Cont...
