conference on current developments in lens design and optical engineering XVIII
作者: Qiu, RongSheng Wu, JianDong Chen, LongJiang Yu, Kun Pang, HaoJun Hu, BaiZhen Shanghai Aerosp Control Technol Inst 1555 ZhongChun Rd Shanghai 201109 Peoples R China
We designed a compact middle-wave infrared (MWIR) lens with a large focal length ratio ( about 1.5:1), used in the 3.7 to 4.8 mu m range. The lens is consisted of a compact front group and a re-imaging group. Thanks t... 详细信息

作者: Macleod, Angus Clark, Christopher Thin Film Ctr Inc Tucson AZ 85716 USA
The introduction of gain into an optical medium is most easily accomplished by reversing the sign of the extinction coefficient. The theoretical expression for reflectance at a simple boundary between a dielectric, lo... 详细信息

conference on current developments in lens design and optical engineering VIII
作者: Bociort, Florian van Turnhout, Maarten Marinescu, Oana Delft Univ Technol Opt Res Grp Lorentzweg 1 NL-2628 CJ Delft Netherlands
Saddle-point construction (SPC) is a new method to insert lenses into an existing design. With SPC, by inserting and extracting, lenses new system shapes can be obtained very rapidly, and we believe that, if added to ... 详细信息

conference on current developments in lens design and optical engineering V
作者: Redding, D Sigrist, N Lou, JZ Zhang, Y Atcheson, P Acton, S Hayden, W CALTECH Jet Prop Lab Pasadena CA 91109 USA
The use of wavefront measurements to deduce the state of multiple optics in a telescope beam train - their misalignments and figure errors - can be confused by the fact that there are multiple potential sources for th... 详细信息

conference on current developments in lens design and optical engineering VIII
作者: Fisher, John Brandywine Opt Inc Chester PA USA
The traditional approach to optical system engineering separates the scene, optics, and detector as static entities, optimizing the design to meet subsystem specifications of aperture, field size, encircled energy, re... 详细信息

conference on current developments in lens design and optical engineering II
作者: Thibault, S INO Opt Engn Div St Foy PQ G1P 4S4 Canada
Generally, a spectrometer uses a diffraction grating to spread the spectral components of a light incident on the diffraction grating on a one-dimensional detector. The detector is composed of pixels linearly distribu... 详细信息

作者: Harvey, James E. Atanassova, Martina Krywonos, Andrey Univ Cent Florida CREOL Orlando FL 32826 USA
Most imaging systems today include a mosaic detector array in the focal plane. optical designers of astronomical telescopes typically produce a design that yields a superb on-axis aerial image in the focal plane, and ... 详细信息

作者: Ryzhikov, Lev 136 Newtown Ave Unit 7 Norwalk CT 06851 USA
Several off-the-shelf optical lenses and lens components are available for use in the design of new optical systems. But there isn't a clear methodology on how effective there can be in a real optical device. It s... 详细信息
