摘要： A system for imaging with a circularly symmetric multifocal aspheric lens is provided for obtaining an extended depth of field. The system includes a camera for capturing an image of at least one object through a circularly symmetric multifocal aspheric lens to provide a blurred image, and a computer system for processing the captured blurred image to provide a recovered image of the object having an extended depth of field. The recovered image may be outputted to a display or other peripheral device. Processing of the blurred image utilizes one of inverse filtering, convolution matrix (e.g., edge sharpening matrix), or maximum entropy. The computer system performing image processing may be in the camera or represent a computer system external to the camera which receives the blurred image. The extended depth of field is characterized by the object being in focus over a range of distances in the recovered image.

摘要： An optical system is disclosed that is compact and is capable of efficiently condensing light into a light receiving optical element. The optical system includes plural light sources and a light condensing portion. The light sources are arranged as an array with M light sources in the horizontal direction and N light sources in the vertical direction (M>N, and M, N>1). The light condensing portion includes a collimator optical element, an anamorphic optical element, and a light-condensing optical element. The anamorphic optical element is arranged such that its magnification in the horizontal direction is greater than that in the vertical direction. Due to the anamorphic optical element, the beam size in the horizontal direction is approximately equal to that in the vertical direction.

摘要： A zoom lens system is composed of three lens groups. Arranged in the order from an eyepoint side are a first lens group G.sub.1 having a positive refracting power, a second lens group G.sub.2 having a positive refracting power and movable along an optical axis during the period of zooming, and a third lens group G.sub.3 having a negative refracting power and movable along the optical axis during the period of zooming. In the second lens group G.sub.2, at least one positive lens includes a lens surface composed of an aspheric surface at least on one of its eyepoint side and object side. Not only a sufficient eye relief is ensured but also various aberrations are corrected throughout the whole zooming range.

摘要： A scanning thermal imager includes means to compensate for a degree of undesirable asymmetry introduced by an element such as a spherical lens operating in an off axis manner. The means can advantageously include an optical element mounted in the optical path with at least one main face at an angle other than normal to the path and arranged to introduce a desired degree of compensating asymmetry.

摘要： A method and apparatus for anamorphically shaping a beam of radiation and for deflecting such beam by 90.degree. independently of beam wavelength shifts within a predetermined wavelength range. The apparatus of the invention comprises an achromatic prism comprising a pair of prism elements of different optical materials. The prism elements are joined together to define a complex prism having four faces which interact with an incident beam to achieve a desired beam shaping and deflection. Two of such faces are parallel, one face being in a plane parallel to the direction of propagation of an incident beam, and the other being in a plane perpendicular to the beam exiting the prism.
