The results of a multicolor infrared survey conducted by the Air Force Geophysics Laboratory are reported. Observations, in one or more broad band colors at effective wavelengths of 4.2, 11.0, 19.8, and 27.4 micrometers are presented with positions for 2363 sources. Ninety percent of the celestial sphere has been surveyed at 11.0 micrometers and about two thirds of this area was covered more than once. (Author)

Earth objects emit natural radiation invisible to the unaided human eye, but visible to infrared scanning devices such as the device developed by Inframetrics, Inc. Such devices serve a number of purposes ranging from detection of heat loss in buildings for energy conservation measures, to examining heat output of industrial machinery for trouble shooting and preventive maintenance. Representative of system is Model 525, a small, lightweight field instrument that scans infrared radiation and translates its findings to a TV picture of the temperature pattern in the scene being viewed. An accessory device permits viewing the thermal radiation in color.

The Status Report covers the progress at the FOM-Institute in constructing the Free Electron Laser for Infrared eXperiments (FELIX). The FELIX project involves the construction and operation of a tunable FEL in the infrared and microwave region, covering the range from 3 micrometers to roughly 3 mm. The first stage of the project is intended to cover the range from 8 micrometers to 80 micrometers. Topics covered in the report include the following: FEL theory and simulations; The electron accelerator; The beam transport system; Electron beam diagnostics; The RF system; The vacuum system; and Housing.

One of the selected research themes of the FOM-Institute for Plasma Physics is 'Research on and with Free Electron Lasers'. The main activity in this area is the Free Electron Laser for Infrared eXperiments (FELIX), for which a proposal was submitted in December, 1986. This proposal addresses the construction and operation of a tunable FEL in the infrared and microwave region, covering the range from 3 micrometers to roughly 3 mm. In subsequent discussions with FOM, it was decided to divide the project into two Stages, the first of which should cover the range from 8 micrometers to 80 micrometers. In May, 1987, the FOM Raad van Bestuur approved the FELIX proposal. After the termination of the screw pinch experiment SPICA at the Institute on October 1st, 1987, the project team was established. Since then, detailed design studies on the various components constituting the FEL were made. Progress is discussed in this Status Report.

The University of Oregon (UO) was a participant in a number of far infrared spectroscopic projects over the past three decades. These include Sub-millimeter Infrared Balloon Experiment (SIBEX), the Balloon Intercomparison Campaign (BIC), and the Infrared Balloon Experiment (IBEX). In addition to these field studies, the UO program contained a detector research component and a laboratory spectroscopy element. Through a productive collaboration with Dr. Carli's group in Italy, with Prof. Ade's group in England and with Dr. Chance of Harvard-Smithsonian, we have made substantial contributions to the development of far infrared spectroscopy as a mature measurement technology for the atmospheric science. This report summarizes the activities during the latest grant period, covering the span from February 22, 1998 to February 21, 2002.

Rapid calculation of the radiant power and the quantum flux emitted by a blackbody source involving any wavelength interval is made possible by the derivations in this paper which introduces the 'normalized cumulative blackbody functions' formulated by the author. Thus, in contrast to conventional blackbody tables, all different radiation temperatures and any wavelength interval are covered by one function which can be compiled in one simple table of very modest volume. The final expressions using these cumulative blackbody functions are uncomplicated equations which can be solved by slide rule operations or, for higher accuracy, by using a desk calculator. Further, the paper introduces an unambiguous symbolism for expressing power and quantum flux radiated by a blackbody source and for expressing performance factors such as conversion yields of broadband radiation detectors. Also equations for calculating the difference in power and quantum flux for blackbody sources against a blackbody background are derived. Illustrative examples for typical situations are calculated.

Several novel scanner concepts were conceived and investigated. The purpose of this work was to find a way to reduce the complexity of imaging and tracking systems. The resulting identification of the Rho-Theta scanner as a promising candidate led to a concentration of effort on this concept. The rho-theta scanner would utilize two superimposed circular reticles;one reticle bearing a radial slot and the second reticle inscribed with an Archimedian spiral slot. The two reticles would rotate and the resulting resolution area would scan the device field-of-view. Geometric and mechanical design considerations were investigated. It was concluded that a rho-theta scanner could be fabricated in breadboard form,and the concept is now ready for exploratory development. (Author)
