摘要： A hybrid lens collimates light emitted by a light source via refraction and reflection. A folded optic element of the lens comprises an outer reflective surface, a lens output surface, and a hollow core comprising a sidewall having a curved profile, a core output boundary, and a core input opening through which the light emitted by the light source enters the hollow core. A reflector of the lens receives the light emitted by the light source, reflects a first portion of the light into the hollow core of the folded optic element, and directly transmits a second portion of the light into the hollow core without reflection by the reflector. In one example, the lens output surface has a diameter of 65 millimeters, the lens has a thickness (between the light source and the lens output surface) of about 13.5 millimeters and provides substantially collimated light with a beam divergence angle of 12 degrees or less.

摘要： A hybrid optic includes a folded optical element with an outer reflective surface, an output surface, and a hollow core comprising a sidewall, a core output surface, and a core input opening through which light emitted by a light source enters the hollow core. A reflector element, coupled to the folded optical element, receives light from the light source, reflects a portion of the light into the hollow core and directly transmits the remaining portion of the light into the hollow core. To reduce the appearance of non-uniformities in the output light, the reflector element is diffuse and white, portions of the folded optical element are diffusely reflective, and/or a glare control diffuser is disposed on the output surface to disperse light transmitted through the core output surface of the hollow core. In this manner, the light coupling efficiency of the hybrid optic is enhanced without producing structured light.

摘要： An optical apparatus for imaging a sample has a scanning apparatus having a laser energizable to direct an input beam of a first wavelength to a reflective scanner that is rotatable about an axis and a toroidal mirror surface that is symmetric about said axis and is disposed to direct scanned laser light of the first wavelength toward the sample in an arcuate scan pattern. A compensator in the path of the input beam is formed to correct one or more aberrations of the toroidal mirror surface. Telecentric collector optics define a collection path that conveys, to a detector, scanned light of a second wavelength that is excited from the scanned sample.

摘要： An optical apparatus has a laser source to direct modulated light toward a scan mirror and objective lens that define a focal surface. Pupil relay optics relay a first pupil at the scan mirror to a second pupil at an eye lens, the pupil relay optics defining an optical axis extending between pupils and having a curved mirror that transmits substantially half of the modulated beam and that has a first center of curvature at the first pupil and a first polarizer in the path of light from the scan mirror to reflect incident light of a first polarization and first angle toward the curved mirror surface and transmit incident light of an orthogonal polarization and second angle, wherein the pupil relay optics direct the modulated light beam twice to the first polarizer, and wherein the modulated light incident the second time is collimated and directed toward the second pupil.

摘要： A Web-based Electronic Controlled Substance (CS) Transfer Management System and Method designed to fully comply with the DEA requirements for a prescription of controlled substances. The system and method allows the buyer to securely order and confirm the receipt of the controlled substances over an existing Internet infrastructure of the buyer such as a Web browser as the buyer's software, thus avoiding the necessity of any additional proprietary software or hardware to be built and installed onto the buyer's computer. The system and method further utilizes various validation functions, related to signing the controlled substance prescription with the utilization of the PKI certificate therefore, completely eliminating the necessity of the paper DEA 222 Form. The transfer of the controlled substances is managed through a secured database server, wherein signed validated orders are posted for fulfillment and reporting to the DEA.

摘要： A volumetric imaging apparatus is energizable to form an image onto a display surface as an input to a monocentric catadioptric imaging apparatus having a light path for image-bearing light from the display surface, wherein the light path extends substantially symmetrically to a vertical plane that extends through a curved relay mirror and a curved primary mirror. The monocentric catadioptric imaging apparatus has reflective surfaces to fold the light path between the curved relay mirror and the curved primary mirror to condition the distribution of the image-bearing light in a horizontal direction. The light path of the monocentric catadioptric imaging apparatus directs light from the curved primary mirror toward a light input surface of a vertical pupil expander that has a light exit surface that is substantially orthogonal to the vertical plane. The light exit surface directs light through a free-form corrector for convergence and toward a windshield for display.
