摘要： An optical pattern generator uses a rotating component that includes a number of deflection sectors containing optical elements. Each sector deflects an incident optical beam by a substantially constant angle although this angle may vary from one sector to the next. The constant deflection angle is achieved by symmetry within the deflection sector, specifically gut-ray symmetry. The rotating component may be combined with an imaging group that produces, for example, image points, spots, or lines displaced along a line locus. The image spots can also be displaced to either side of a line, for example by introducing a tilt in the orthogonal direction or by introducing light beams at various angles to the plane of symmetry.

摘要： An optical scan engine includes a rotatable component, for example a disk or drum. The rotatable component includes a plurality of scan sectors that are arranged around the rotation axis and that lie substantially in a plane of rotation. Each scan sector includes a pair of reflective surfaces that typically are radially-facing. The incident optical beam typically propagates along a radial direction (e.g., towards the rotation axis) and each pair of reflective surfaces deflects the incident optical beam by approximately 180 degrees as that pair rotates through the incident optical beam. The deflected optical beam has a virtual image located on the rotation axis. As a result, the real image of the deflected optical beam rotates around the rotation axis at the same angular velocity as the scan sectors. Different scan sectors can be designed to yield diffeent deflections in the axial direction. The addition of a third reflective surface to each scan sector can be used to generate image points that are fixed in space as the scan sector rotates.

摘要： A compact zoom lens system having four injection-molded singlet lens elements is described. In one embodiment, the compact zoom lens system includes a lens carrier and first and second lens elements coupled to the lens carrier. One surface of the first or second lens elements having a diffractive optical surface disposed thereon to correct chromatic aberrations of light passing therethrough. The lens carrier moves the first and second lens elements axially to change a focal length of the lens system. Third and fourth lens elements are fixed on either side of the first and second lens elements. The lens carrier includes an aperture stop placed proximate to the diffractive optical surface to correct chromatic aberrations over an entire range of focal lengths. The first lens element is made out of flint-like material while the other lens elements are made out of crown-like material. Moreover, the zoom lens system includes an anti-aliasing surface on one of the lens elements to control aliasing effects. A plurality of light suppression elements are provided to suppress stray light paths from scattering across a detector array of the zoom lens system.

摘要： An endoscope includes a disposable probe and a non-disposable focusing ocular. The probe includes a transfer module assembly including one or more relay modules, and an objective element including a distal glass window, a molded plastic prism and three molded plastic lenses. Each of the relay modules contains an entry glass rod, an intermediate glass rod, and an exit rod, each having flat end surfaces and two identical molded plastic doublets. The elements of the ocular are all of glass and include an axially movable focusing doublet and two non-movable doublets. The disposable probe introduces certain aberrations into the image. The non-disposable focusing ocular corrects these aberrations. A single curved surface is formed on the distal glass window of the probe; all other curved optical surfaces of the disposable probe are formed on molded plastic members, thereby reducing the cost of the probe sufficiently to be cost-effective for single patient, disposable use.

摘要： A pocket-sized microform reader is realized by employing a unique lenticular (screen) assembly and a projection lens assembly, the latter permitting a fold in the middle of an optical path allowing the size requirements of such a reader to be met. The cooperation between the lenticular screen and the projection lens assemblies permits sufficient brightness to be obtained and the lenticular screen assembly defines a non wasteful exit pupil of limited dimensions consistent with a pocket-sized reader.
