The detection of hidden subsurface objects in the infrared wavelength band by identifying their thermal properties

The next survey mission, ASTRO-F, is scheduled for launch in 2005. This is the first Japanese satellite dedicated to infrared astronomy. The primary purpose of this project is to investigate the birth and evolution of galaxies in the early universe through deep, wide-field surveys at wavelengths ranging from 2 to 200 microns. In the far-infrared wavelength band, ASTRO-F will conduct an all-sky survey like the IRAS survey with several tens of times higher sensitivity and several times better spatial resolution. In the near- and mid-infrared, wide area sky-surveys will be conducted over pre-selected portions of the sky in 13 bands ranging from 2-200microns. In addition to these photometric surveys, low-resolution spectroscopic capabilities are available for all wavelength bands. The ASTRO-F mission will produce a fundamental database for the next generation of advanced observatories, for example Herschel, and JWST, and will complement the SIRTF mission by virtue of its wide sky coverage.

Recognition Of Objects

Within the course of the present research, the mathematical and algorithmic supporting of hardware-software system of control and monitoring that uses images obtained in visible and infrared wavelength band as the source of initial data has been developed and implemented. The paper defines the conditions for obtaining an image, the quality of which is sufficient to detect a target object. The front-end of software package has been worked out that allows an operator to address tasks on detecting, tracking and identifying objects without specific knowledge and experience.

Regular Arrays

Infrared (IR) microlens arrays (MLA) have attracted increasing interest for use in infrared micro-optical devices and systems. However, the beam homogenization of IR laser light is relatively difficult to achieve because most materials absorb strongly in the IR wavelength band. In this paper, we present a new method for the application of double-sided quasi-periodic chalcogenide glass (ChG) MLAs to infrared laser homogenization systems. These are non-regular arrays of closely spaced MLAs. The double-sided MLAs were successfully prepared on the ChG surface using a single-pulse femtosecond laser-assisted chemical etching technique and a precision glass molding technique. More than two million close-packed microlenses on the ChG surface were successfully fabricated within 200 min. By taking advantage of ChG’s good optical performance and transmittance (60%) in the infrared wavelength band (1~11μm), the homogenization of the IR beam was successfully achieved using the ChG quasi-periodic MLA.

Rectification Process

The Antarctic mosaic project is a joint National Oceanic and Atmospheric Administration/United States Geological Survey (NOAA/USGS) project to produce a photomosaic map at 1:5 000 000 scale. The mosaic will be made as a collage of rectified images from the polar-orbiting NOAA-6 satellite. The near-infrared wavelength band of 0.725 to 1.10 μm, with a spatial resolution of 1.1 km, will be used. The NOAA-6 data are obtained from the McMurdo station receiving facility and from the archive of recorded data. Examples of imagery from both sources are presented. The operational plan including the processing flow chart, rectification process, progress to date, and problems to be faced are discussed. Applications of the mosaic are discussed as well as possible NOAA-6 applications to Antarctic investigators.
