Abstract: An improved curing oven is disclosed. The present invention (10) provides an improved curing oven which cures materials with electromagnetic radiation in the ultraviolet region. The invention consists of a surface (12) lined with a layer of material (14) effective to radiate ultraviolet radiation in response to the application of infrared radiation. In a specific illustrative implementation, the invention (10) includes a second surface (18) overlying the first surface (12) providing a passageway therebetween. The oven temperature is set and maintained by a conventional temperature controller (20). Tne temperature controller (20) measures the oven temperature and controls a valve (22) which adjusts the gas pressure from a gas supply (24) to a set of oven burners (26). Air is supplied through inlet ports (28) included in the second surface (18).

Abstract: A deformable mirror system for reduction of projected image distortion in an optical system (30). A mirror (20) located near an intermediate image plane (25) is adapted to correct for ray direction. The distortion in the image is predetermined, and the mirror is contorted in a manner determined by the distortion to be corrected; relationships are prescribed for the desired contortion. Reduction in distortion can be achieved by placement of a mirror near the image plane; further reduction can be achieved by the placement of an additional contorted mirror at a subsequent image-forming aperture in the optical system. A particular example of an application for this system is aircraft simulators.
Abstract translation: 可变形反射镜系统减小光学系统（30）中的投影图像的失真。 位于中间图像平面（25）附近的镜子（20）适于校正光线的方向。 图像中的失真是预定的，并且反射镜以由待校正的失真确定的方式失真; 为所需的变形规定了关系。 通过在镜像平面附近放置镜子可以减少失真; 通过在光学系统中的后续成像孔处放置额外的变形镜可以实现进一步的减小。 该系统应用的一个特例是飞行模拟器。

Abstract: An adaptive electrooptical lens system for use in optical data storage systems, optical phased arrays, laser or other optical projectors, and raster scanning devices, and the like. The invention provides an electrooptical means for scanning an optical beam or moving an optical storage or retrieval point. Beam movement is achieved electrooptically, by changing the index of refraction of an electrooptical material by controlling electric fields applied thereto. A plurality of electrodes are disposed on one surface of the electrooptic material and a ground electrode is disposed on the other. The electrodes are adapted to apply electric fields derived from a voltage source to the electrooptic material that selectively changes its index of refraction and provides for a predetermined index of refraction profile along at least one dimension thereof, thus forming a lens. By appropriately forming the electrode pattern and properly controlling the voltages applied thereto, differing lens shapes may be formed. Since the response times of the electrooptic materials employed in the present invention are on the order of nanoseconds (10-9 sec) or less, the intrinsic response frequency of the lens system is 109 Hz or more. The present invention thus increases the data storage and retrieval capacity of optical systems in which it is employed.

Abstract: An improved radiation source, exploiting the spontaneous radiation generated from the interaction of an electron beam and a conductive grating. Conditions are defined for generating coherent or noncoherent radiation, and for extending the tunability of the radiation source from millimeter, IR, visible and UV wavelengths to x-ray wavelengths, and for generating multiple wavelenghts simultaneously. Conditions are disclosed for enhancing the intensity of the spontaneous radiation, and for modulating the radiation

Abstract: La source de rayonnement améliorée ci-décrite exploite le rayonnement spontané produit par l'interaction d'un faisceau d'électrons et d'un réseau conducteur . Des conditions sont définies pour produire un rayonnement cohérent ou incohérent, et pour étendre la plage de syntonisation de la source de rayonnement depuis les longueurs d'ondes millimétriques, infrarouges, visibles et ultraviolets jusqu'aux longueurs d'ondes à rayon X, et pour produire simultanément des longueurs d'ondes multiples. Des conditions sont décrites pour augmenter l'intensité du rayonnement spontané et pour moduler le rayonnement.
