Transition Theory of Small-area Spectrum Radiative Intensity and its Application

摘要

Nowadays, The calibration of special optics equipment of some kind of missile is based on experiential model of mutual verification and provement which can not insure the traceability of optics value. So there exists a blank in optics metrological calibration and can't realize equipment metrology support. Ainming at aboved problems, a new ray radiation calibration technology based on transition theory of small-area spectrum radiation intensity is presented in this paper which resolves the difficult problem of small-area and low radiation intensity of lambert optical source in the process of ray radiation transfer. Basing on the deduction in radiation intensity digital response equation and linear response equation of narrow-band wavelength, the ray radiation output of optics equpment can be transformed into the ray radiation output of national standard optical source, which insures the consistency and traceabilty of value transfer. Finally, the function relationship of radiation intensity of special optics aiming equipment, ray radiation calibration system and national standard optical source is set up and validated in this paper and there realize metrological calibration of special optics aiming equipment of some kind of missile.
