Abstract
A radiation source is presented that exhibits an improved efficiency of converting input energy into a quasi-blackbody output beam. A wavelength selective element can be included to transit one or more narrow bands of this radiation for use in spectroscopy. The intensity of the output beam can be varied quickly, thereby decreasing measurement times and enabling synchronous detection techniques to be implemented at reasonable frequencies. A feedback mechanism can be integrated into this device to enable accurate control of the blackbody temperature. This radiation source can be manufactured by conventional integrated circuit manufacturing techniques, thereby producing an inexpensive quasi-blackbody source of accurately and repeatably controlled performance.
