STEEP320 is a program intended for numerical modeling of radiation characteristics of blackbody cavities. The program is applicable to design optimization and performance assessment of blackbodies used as standard reference sources in radiating thermometry (pyrometry), thermography, radiometry, photometry, and for optical radiation detector calibrations (e.g., in remote sensing).
STEEP320 is a simplified version of STEEP321. Like their predesessor STEEP3, STEEP320 is based on the proprietary algorithm of the Monte Carlo ray tracing method implemented for an axially symmetric cavities formed by rotation of polygonal line around the axis. The algorithm performs the modeling of various viewing conditions of cavity with arbitrary axially symmetric temperature distribution. The Gray Uniform Specular-Diffuse (GUSD) model of reflection is used for optical properties of each cavity surface.
New, faster ray tracing algorithm and Mersenne Twister Random Number Generator are implemented in STEEP320, what ensures reliability of results at the tracing up to 109 rays.
