摘要： An optical system has a light source of an optical beam, and a wavefront distortion generator that introduces a known wavefront distortion into at least one wavelength component of the optical beam prior to the formation of an intermediate image. A focusing device receives the optical beam, produces the intermediate image of the optical beam, and outputs the optical beam. A wavefront distortion corrector, after the formation of the intermediate image, introduces a wavefront distortion correction into each component of the optical beam into which the known wavefront distortion was introduced by the wavefront distortion generator. The wavefront distortion correction is the reverse of the known wavefront distortion introduced into the optical beam by the wavefront distortion generator.

The system includes an illuminator for providing a first beam of electromagnetic energy at a first wavelength; a source for providing a second beam of electromagnetic energy at a second wavelength; and an arrangement for compensating wavefront errors in the second beam using a bias representative of a comparison between the first wavelength and the second wavelength.

摘要： A helmet/head mounted display including a display image source and a reflective visor for each eye. The image source includes a fiber optic cover plate with a planar input surface and a curved output surface which has curvature providing the correct curvature. The image source further includes a self-emitting device such as a field electrode display or electroluminescent device, or a polymer dispersed liquid crystal (PDLC) sandwiched between a thin, sharply tapered fiber optic plate and the fiber optic cover plate. For the PDLC image source, back light illumination is introduced through the tapered fiber optic plate, passes through or is scattered by the PDLC and then through the fiber optic face plate to the visor, for reflection to the observer's eye. The fiber optic face plate is constructed with a very low numerical aperture. The fibers of the cover plate are oriented toward the eye as seen in the reflection from the visor to reduce undesirable reflected light. No lenses or beam splitters are in the light path between the image source and the visor.

摘要： An imaging polarimeter sensor includes an achromatic beam-splitting polarizer that receives a polychromatic image beam of a scene and simultaneously produces a first polarized polychromatic image beam and a second polarized polychromatic image beam. The second polarized polychromatic image beam is of a different polarization than the first polarized polychromatic image beam and is angularly separated from the first polarized polychromatic image beam. The achromatic beam-splitting polarizer preferably includes a Wollaston prism through which the polychromatic image beam passes, and at least one grating through which the polychromatic image beam passes either before or after it passes through the Wollaston prism. An imaging detector receives the first polarized polychromatic image beam and the second polarized polychromatic image beam and produces an output image signal responsive to the first polarized polychromatic image beam and the second polarized polychromatic image beam.

The one-to-one relay combines the outputs from two different spectral image sources, such as blue and red image sources. The refractive projection lens further combines the output from a third spectral image source, such as a green image source, with the combined images from the other two image sources relayed through the one-to-one relay to produce a single output. The one-to-one relay includes three modules, a spherical primary module, a spherical secondary module and a spectral combining module.

摘要： An optical system has an extended boresight source including a boresight light source that produces a light beam, a condenser lens that receives the light beam from the boresight light source, a spatial light integrator that receives the light beam from the condenser and mixes the light beam to reduce its spatial inhomogeneities, a constriction through which the light beam from the spatial light integrator is directed, and a collimator that receives the light beam which passes through the constriction and outputs a boresight light beam. The boresight light beam is typically provided to a sensor imager that uses the boresight light beam to establish its centroid.

摘要： A kinoform optical element (KOE) has different surface relief heights in different zones of the kinoform surface, in order to optimize the first order diffraction efficiency in each zone. By increasing the first order diffraction efficiency, noise as well as ghost image problems may be reduced and contrast and resolution may be enhanced. In an exemplary embodiment, each zone, or even different areas of the same zone, has a non-constant step height that is preferably defined by a predetermined relationship between an optimal step height and an associated predominant angle of incidence associated with that particular zone or area. In the case of an optical system having a relatively large aperture and a relatively narrow field of view, each point of the KOE sees the entire image; the associated predominant angle of incidence at that point may be defined by a so-called "marginal" ray from the center of the entire image space (i.e., on the optical axis and at the effective "middle" of the usable depth of field). In the case of an optical system having a relatively small aperture and a relatively wide field of view , each point of the KOE sees only a portion of the image; the associated predominant angle of incidence at that point may be defined by an exemplary ray from the portion of the image space that is visible from that point. Since the optimum surface relief is dependent on the angle of incidence of the radiation relative to the orientation of the surface, diffraction efficiency can also be optimized by providing the kinoform with a non-planar surface contour such that all the predominant rays are normal to the active surface, in which case all the steps may have the same height.
摘要翻译： Kinoform光学元件（KOE）在kinoform表面的不同区域中具有不同的表面浮雕高度，以便优化每个区域中的一阶衍射效率。通过增加一级衍射效率，可以降低噪声以及重影图像问题，并且可以提高对比度和分辨率。在示例性实施例中，相同区域的每个区域或甚至不同区域具有非恒定台阶高度，其优选地由最佳台阶高度与与该特定区域相关联的相关联的主要入射角之间的预定关系限定，或区。在光学系统具有相对较大的光圈和相对较窄的视野的情况下，KOE的每个点看到整个图像; 在该点处的相关联的主要入射角可以通过从整个图像空间的中心（即，在光轴上和在可用景深的有效“中间”）的所谓“边缘”射线来定义，。在光学系统具有相对小的孔径和相对宽的视场的情况下，KOE的每个点仅仅看到图像的一部分; 可以通过从该点可见的图像空间部分的示例性射线来定义在该点处的相关联的主要入射角。由于最佳表面浮雕取决于辐射相对于表面的取向的入射角，所以衍射效率也可以通过提供非平面表面轮廓的kinoform来优化，使得所有主要的光线垂直于活动表面，在这种情况下，所有步骤可能具有相同的高度。
