STEEP321
The program STEEP321 is 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).
STEEP321, as its predecessor, STEEP3, 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 Uniform Specular-Diffuse (USD) model of reflection is used for optical properties of each cavity surface.
New, faster ray tracing algorithm is implemented in STEEP321, as well as Mersenne Twister Random Number Generator that ensures reliability of results at the tracing up to 109 rays.
The requirements for hardware and software are the following:
