摘要： A virtual image display optical system. The system includes an image source, a combiner, and a relay group. The relay group is a catatrioptic relay group that includes a reflective optical element, and a refractive lens group that includes at least one doublet and a diffractive lens. For some applications, the catatrioptric relay group may be replaced by a hybrid refractive-diffractive relay group, thus eliminating the reflective element. The diffractive optical element of the hybrid optical element is encoded on one side of a lens. The hybrid optical element forms a refractive/diffractive achromat to provide for primary chromatic aberration correction. The refractive lens group is also an achromat to provide for chromatic aberration correction. Power distribution between the hybrid optical element and the refractive lens group is such that secondary chromatic aberration of the refractive lens group is balanced out by the secondary chromatic aberration of the hybrid optical element. The diffractive optical element is designed using higher order wavefront correction terms encoded on one side to reduce spherochromatism and secondary spherochromatism of the relay group. One lens may have a conic or an aspherical surface to further reduce the spherochromatism and secondary spherochromatism. Asymmetrical aberration and distortion resulting from the combiner are compensated for by the reflective optical element. To minimize the residual aberration of the optical system, the reflective optical element is tilted and/or decentered. The system has a relatively wide spectral bandwidth, has good image quality, has simple optics, is ultracompact, and provides wide field coverage and large field overlaying.

摘要： A zoom lens (10) has a first lens group (12), a second lens group (14) and a third lens group (16). The first lens group relays an outside scene to an intermediate plane. The second lens group varies magnification of the relayed image from the first lens group. Also, the second lens group includes at least one diffractive optical element. The third lens group compensates for focus shift and focuses the wavefront onto the viewing plane.

A third optical element 54 having a refracting convex surface 56 and a refracting convex surface 58 is also employed. In another embodiment, a four-element biocular system 60 is disclosed as having an optical element 62 having a refracting concave surface 64 and a refracting convex surface 66, a refractive-diffractive hybrid optical element 68 having a diffractive surface 70 and a refracting convex surface 72, an optical element 74 having a refracting convex surface 76 and a refracting concave surface 78, and an optical element 80 having a refracting concave surface 82 and a refracting convex surface 84. The diffractive surfaces 44 and 70 have a kinoform profile 102 a-d or approximated kinoform profiles 112a-d and 122a-d. Both versions of the biocular eyepiece 40 and 60 provide a biocular eyepiece which has fewer lens elements and a shorter overall length than conventional designs. Both versions of the biocular eyepiece 40 and 60 may be used in combination with a cathode ray tube 12 for magnification of images generated therein.

摘要： A common-aperture optical system includes a reflective telescope having a common boresight, an entrance pupil, an exit pupil, and a beam path extending from the entrance pupil to and beyond the exit pupil. A beam splitter intersects the beam path so that the beam path is incident upon the beam splitter. A light sensor is positioned to receive an input light beam traveling along the beam path after the beam path intersects the beam splitter and passes the exit pupil of the reflective telescope. A light source produces an output light beam incident upon the beam splitter and positioned to inject the output light beam into an inverse of the beam path and toward the entrance pupil of the reflective telescope. A diverger corrects at least one of the input light beam and the output light beam.

摘要： An imaging sensor system images in two different spectral bands a light beam traveling on a light path from a target. The sensor system includes an imaging sensor operable to image light of the two different spectral bands, a common optics having at least one reflective or refractive optical element, and a wavelength-selective beamsplitter on the light path between the target and the imaging sensor. The wavelength-selective beamsplitter splits the light beam into two subbeams, one subbeam for each of the two different spectral bands, that are respectively incident upon two different locations of the imaging sensor. The imaging sensor may be used to detect buried explosive mines.
