Phase retrieval camera for testing NGST optics
The NGST Phase Retrieval Camera (PRC) is a portable wavefront sensor useful for optical testing in high-vibration environments. Primary applications of the PRC are testing and experimenting with NGST technology demonstrator mirrors, along with exploring other wavefront sensing and control problems not easily studied using WCT. An overview of the hardware and testing results will be presented.
NGST phase retrieval camera design and calibration details
This presentation will detail the packaging and hardware chosen for the PRC, the PRC software, and calibration of the instrument.
Recent improvements to the AVIRIS sensor: flight season 2000
This paper describes recent modifications to the instrument over winter maintenance cycles not covered elsewhere, and discusses the rationale leading up to the changes, implementation and results.
Imaging Spectroscopy and the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS)
Imaging spectroscopy is of growing interest as a new approach to Earth remote sensing. The Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) was the first imaging sensor to measure the solar reflected spectrum from 400 to 2500nm at 10 nm intervals.
AVIRIS: A New Age Approach to Earth Remote Sensing
An imaging spectrometer measures a contiguous spectrum of light for each spatial element of an image.
