Lens design using group indices of refraction

Autor: Arthur H. Vaughan

Publikováno v: Journal of Modern Optics. 43:1683-1700

An approach to lens design is described in which the ratio of the group velocity to the speed of light (the group index) in glass is used, in conjunction with the more familiar phase index of refraction, to control certain chromatic properties of a s

Publikováno v: Acta Astronautica. 35:99-108

We describe an integrated instrument that will perform the functions of three optical instruments required by a Pluto Fast Flyby mission: a near-IR spectrometer (256 spectral channels, 1300–2600 nm), a two-channel imaging camera (300–500 nm, 500�

Telescope simulators for Hubble: an overview of optical designs

Autor: Michel Saisse, Joe H. Sullivan, Arthur H. Vaughan, Pam Davila, H. John Wood, Paul D. Atcheson, Renee M. Saunders

Publikováno v: Applied optics. 32(10)

Various optical configurations for Hubble Space Telescope simulators have been proposed, and some are being built for use as verification tools to characterize the performance of second-generation instruments during ground testing. We describe the Hu

Simplified solution of diffraction from a Lyot system

Autor: Yaujen Wang, Arthur H. Vaughan

Publikováno v: Applied optics. 27(1)

This paper presents a derivation of a simplified analytical solution of diffraction from a Lyot (1939) system designed for observation of the solar corona outside of eclipses. Applying the theorem of Papoulis (1986) to simplify the calculations, a si

The Optical Design of the 40-in. Telescope and of the Irenee DuPont Telescope at Las Campanas Observatory, Chile

Autor: I. S. Bowen, Arthur H. Vaughan

Publikováno v: Applied optics. 12(7)

The optical specifications of two astronomical telescopes designed to permit wide-field photography with critical definition are presented and compared. The 40-in. (1.016-m) and DuPont 100-in. (2.54-m) telescopes use modifications of the Ritchey-Chre

The Galaxy Evolution Explorer (GALEX), a NASA Small Explorer Mission planned for launch in Fall 2002, will perform the first Space Ultraviolet sky survey. Five imaging surveys in each of two bands (1350-1750Å and 1750-2800Å) will range from an all-

Compact Doppler magnetograph

Autor: Arthur H. Vaughan, Philip I. Moynihan, Alessandro Cacciani, Alexander Ruzmaikin

Publikováno v: SPIE Proceedings.

We designed a low-cost flight instrument that images the full solar disk through two narrow band filters at the red nd blue 'wings' of the solar potassium absorption line. The images are produced on a 1024 X 1024 charge-coupled device with a resoluti

Application of group indices of refraction to achromatic lens design

Autor: Arthur H. Vaughan

Publikováno v: SPIE Proceedings.

An approach to color correction is described in which the ratio of the group velocity to the speed of light in vacuum (the group index of refraction) in glass is used, in conjunction with the more familiar phase index of refraction, to control longit
