NASA SBIR abstracts of 1992, phase 1 projects
The objectives of 346 projects placed under contract by the Small Business Innovation Research (SBIR) program of the National Aeronautics and Space Administration (NASA) are described. These projects were selected competitively from among proposals submitted to NASA in response to the 1992 SBIR Program Solicitation. The basic document consists of edited, non-proprietary abstracts of the winning proposals submitted by small businesses. The abstracts are presented under the 15 technical topics within which Phase 1 proposals were solicited. Each project was assigned a sequential identifying number from 001 to 346, in order of its appearance in the body of the report. Appendixes to provide additional information about the SBIR program and permit cross-reference of the 1992 Phase 1 projects by company name, location by state, principal investigator, NASA Field Center responsible for management of each project, and NASA contract number are included
Photoconductive THz emitters and detectors on the basis of InGaAs/InP for terahertz time domain spectroscopy
The topic of the present thesis is the development and investigation of photoconductive semiconductor structures for the opto-electronic generation and detection of terahertz (THz) radiation by the use of femtosecond fiber lasers at emission wavelengths of 1550 nm and 1030 nm. Aside from investigating fundamental physical questions, the main motivation for the development of such semiconductor structures is to satisfy the rising demand for compact, cost-efficient and rapid THz measurement systems. The goal of this thesis is to expand the field of application of THz measurement beyond scientific research towards industrial process control by developing optimized devices and systems
Cumulative index to NASA Tech Briefs, 1986-1990, volumes 10-14
Tech Briefs are short announcements of new technology derived from the R&D activities of the National Aeronautics and Space Administration. These briefs emphasize information considered likely to be transferrable across industrial, regional, or disciplinary lines and are issued to encourage commercial application. This cumulative index of Tech Briefs contains abstracts and four indexes (subject, personal author, originating center, and Tech Brief number) and covers the period 1986 to 1990. The abstract section is organized by the following subject categories: electronic components and circuits, electronic systems, physical sciences, materials, computer programs, life sciences, mechanics, machinery, fabrication technology, and mathematics and information sciences
