1. The spectral distribution of a black body radiation is described by Planck's.

2. By using the Tikhonov Regularization numerical inversion of black body radiation are discussed.

3. The region is then scanned for black body radiation in a medium infrared waveband.

4. The ratio of the intensity of black body radiation at four wavelengths was calculated by the blackbody radiation law.

5. The actual object heat radiation model is established after comparing the actual object heat radiation to the ideal black body radiation.

6. A simple and efficient method for determining area temperature distribution of the inverse black body radiation problem is presented. It is different from previous works.

7. By using the Tikhonov Regularization Method, the related techniques for the numerical inversion of black body radiation are discussed.

8. With the present lasers, X-ray microscopy can be made using narrow band emission or black body radiation from laser plasmas.

9. In order to solve nonlinear errors in measurement, the principle of the black body radiation temperature sensor of optical fiber and nonlinear error source are analysed.
