Science drivers for UV Optical Space Detector
نویسنده
چکیده
I present science goals and mission concepts that require ultraviolet-optical detector development for space-based applications during the next two decades. A broad range of science objectives in NASA’s Astronomical Search for Origins and Structure and Evolution of the Universe themes can be addressed by imaging and spectroscopic studies at UV-optical wavelengths, from detecting and characterizing extra-solar planets to tracing large-scale structure and the evolution of galaxies via intergalactic absorption lines. I emphasize the need for detector development that yields large formats, high quantum efficiencies, very low intrinsic noise, and broad spectral response. I also strongly encourage the development of photon-counting energy-resolving detectors for UV-optical applications in both 1-d and 2-d array formats.

متن کاملAnalysis of New Laser Warning Technologies to Propose a New Optical Subsystem
In this paper, after a brief overview on laser warning system (LWS), a new structure for an optical array that is used in its optical subsystem is introduced. According to the laser threats’ wavelengths (0.5 – 1.6 µm) and our desirable field of view (FOV), we used 6 lenses for gathering the incident radiation and then optimized the optical array. Lenses’ radius, their se...

متن کاملClose Following Behavior: Estimation of Desired Gap Headway Using Loop Detector Data (TECHNICAL NOTE)
The desired gap headway of drivers, while close following, represents the main parameter in determining the following distance between vehicles. This paper uses the raw individual vehicles data taken from loop detectors for millions of vehicles used M25 and M42 in order to estimate the gap headway distributions between successive pairs of vehicles. The data used in this paper were filtered so...
