Abstract:
Diffractive (or binary) optics may provide a key technology
for the development of lightweight, high-performance optical
systems for space applications. In particular, diffractive optics
technology may make significant improvements in several of the
instruments that are being planned for the Geostationary Earth
Observatory (GEO). Phase I will investigate the following topics:
the design of an all-diffractive, narrow-band telescope for the
lightning mapper sensor (LMS); the design of diffractive-
refractive hybrid lenses for application in the aft-optical
systems, such as the GeoPlatform High-Resolution Interferometer
Sounder (GPHIS) and the NOAA GOES N multi-spectral imager; and the
use of diffractive elements to athermalize infrared optical
systems. Using computer ray-traced methods, this project will
characterize the imaging properties of the optical systems. In
addition, the fabrication processes that can be used to
manufacture the diffractive elements will be specified, and a cost
analysis for a prototype optical system will be provided. Phase II
will be devoted to fabricating a prototype diffractive optics
system for an instrument slated for geostationary observations.
Potential Commercial Application:
Potential Commercial Applications: This work will benefit space,
military, and commercial applications that require lightweight,
high performance optical systems. System applications include
lidar systems for atmospheric and pollution monitoring; coherent
communications; and narrowband and broadband imaging systems for
the ultraviolet, visible and infrared wavelength regions.
