摘要： A low cost optical viewing device for viewing a remote location comprises three sections of an objective lens, relay lens and eye piece. However, in contrast to prior art optical viewing devices, all three sections of the present invention are free of conventional and relatively expensive glass rods. The preclusion of the glass rods leads to an overall lower cost (e.g., disposable) optical viewing device (e.g, borescope and endoscope). In addition, the optical viewing device of the present invention achieves lower cost by the use of a combination of molded plastic lenses and glass lenses. In accordance with still another important feature of this invention, the method of illuminating the remote location to be viewed is accomplished by using low cost plastic optical fibers which are twisted so that the field of illumination is increased and may be tailored to match (or be no less than) the size of the field of view of the optical viewing device. Still another significant feature of the present invention is its low weight as compared to prior art devices. This low weight is obtained both through the use of the combination of lightweight plastic lenses and glass lenses as well as by the fact that the lenses are separated by an air space (as opposed to heavy glass rods). This light weight feature of the present invention leads to ease of manipulation by the end user.

摘要： A nonimaging radiant energy device may include a hyperbolically shaped reflective element with a radiant energy inlet and a radiant energy outlet. A convex lens is provided at the radiant energy inlet and a concave lens is provided at the radiant energy outlet. Due to the provision of the lenses and the shape of the walls of the reflective element, the radiant energy incident at the radiant energy inlet within a predetermined angle of acceptance is emitted from the radiant energy outlet exclusively within an acute exit angle. In another embodiment, the radiant energy device may include two interconnected hyperbolically shaped reflective elements with a respective convex lens being provided at each aperture of the device.

摘要： A ring lens assembly for an optical viewing device is presented. The ring lens assembly includes a ring shaped lens adapted for mounting at the end of an optical viewing device for viewing a remote location. The optical viewing device comprises an objective lens section, a relay lens section and an eye piece section. Further, the optical viewing device has an inner tube wherein the optics is housed and an outer tube. A plurality of optical fibers are disposed between the inner and outer tubes to provide illumination of the field of view. The ring shaped lens is a negative curvature lens or a prism-like lens for increasing the field of illumination. Alternatively, the lens is a flat lens and the optical fibers twisted to increase the field of illumination. Also, a cleaning tube is disposed between the inner and outer tubes. The cleaning tube terminates short of the end of the inner tube. An opening or channel is formed at the end of the inner tube adjacent to the cleaning tube. Accordingly, cleaning fluid travels down the cleaning tube and impacts the inner surface of the ring shaped lens. The cleaning fluid is deflected off of the inner surface of the ring lens, flows through the opening in the inner tube and impacts the outer surface of the first lens in the objective lens section thereby providing cleaning action.

摘要： A laser discrimination filter based on temporal coherence is presented. This filter comprises a multilayer device with "thick" layers such that the optical thickness of each layer is greater than the coherence length of the ambient light, but still much smaller than the coherence length of the laser light of interest. Thus, the spectral response of the device of this invention becomes dependent on the degree of temporal coherence of the incident light. If white light strikes the filter, multi-beam interference will not occur because of its short coherence length. The device acts like a stack of partially reflecting mirrors. If the laser light strikes the filter, multi-beam interference will still take place because of the long coherence length of the laser light. This causes the device to have different transmitting characteristics for laser light and white light. Therefore, this device functions as a laser discrimination device.
摘要翻译： 提出了一种基于时间相干性的激光识别滤波器。 该滤波器包括具有“厚”层的多层器件，使得每层的光学厚度大于环境光的相干长度，但仍远远小于感兴趣的激光的相干长度。 因此，本发明的装置的光谱响应取决于入射光的时间相干程度。 如果白光照射过滤器，则由于其短的相干长度而不会发生多光束干涉。 该装置像一堆部分反射镜一样起作用。 如果激光照射过滤器，则由于激光的长相干长度，仍然会发生多光束干涉。 这使得该装置对于激光和白光具有不同的透射特性。 因此，该装置用作激光识别装置。
