Abstract: A light-emitting device, comprising at least a first light source (101) and a second light source (102) is provided. The light source further comprises a first collimating means (111) for collimating light from the first light-source and a second collimating means (112) for collimating light from said second light source wherein the output areas of the collimating means at least partly overlaps. A light guiding means (107) is arranged between said light sources and said collimating means for guiding light from the first light source to the first light collimating means, and from the second light source to the second collimating means. A light-emitting device of the present invention can provide well mixed and collimated light even though there is a distance between the light sources and the collimating means.

Abstract: The invention relates to an imaging system in which a diffractive optical element is used by both the illumination beam path and the imaging beam path. Said diffractive element operates in the reflection mode or transmission mode according to the specifications of the system design. At least one of the imaging optical elements provided in the beam path of the inventive diffractive beam splitter for imaging systems is used for both the illumination beam path and the imaging beam path. Said element represents a diffractive optical element (DOE) and requires no spatial separation between the imaging beam path and the illumination beam path in the object space by using different diffraction arrays. The number of reflective optical elements can be decreased by using diffractive optical elements, resulting in the cost of the system being reduced and the service life of the optical components being increased by using a low-power EUV source.

Abstract: An optical system for illuminating and viewing a target (15) in which an illumination element (16) and a receiving element (13) are disposed behind a single optical window (14), and which obtains data essentially free of backscatter and stray light. The optical window (14) is configured such that is defines a shape having at least one focal curve, i.e., an ellipsoid shaped dome. The illumination element (16) and the receiving element (13) are geometrically positioned on the focal curve plane or in proximity of the focal curve plane, such that, when iluminating, rays from the illumination element internally reflected from the optical window (14) will not incident on the receiving element (13).

Abstract: An image mover having a reduced sizing for the steering mirror and rotator assembly and associated components and motors is disclosed. The image mover (10) comprises a relay lens (18) to collimate and relay angular information of the light image from the projector scanning mirror (16). Rotators, such as K-mirror, pechan prism, or dove prism, rotate the collimated image responsive to horizontal movement of the image. A restoring lens (22), which can either be a fixed focal length or a zoom lens, restores the collimated light image proportional to the angular information of the image produced by the projector. The restored diverging image is projected to a steering mirror (24) and steered onto a viewing surface (26) in real time.

Abstract: An apparatus is provided for magnifying the image of distant objects which has the unique feature that objects to be viewed can be at any arbitrarily large distance from the apparatus. In addition, the apparatus does not require positioning of the eye at the exit pupil of the instrument; it does not require centering of the eye on the optic axis of the instrument; and it does not require refocusing for different object distances. Still, it provides erect, non-inverted images to the viewer. The invention includes a positive optical element (53) defining an optic axis for the apparatus and having a positive focal length for converging an incoming bundle of rays of electromagnetic radiation. Also included is a negative optical element (51) aligned with the optic axis and separated from said positive optical element by a distance d1, with the negative optical means having a negative focal length that is substantially equal in magnitude to the focal length of the positive optical means and having a focal point on the optic axis.
