| Abstract: | Based on radiation heat transfer and considering the effect of factitious illumination and the radiation of background objects under natural illumination , the paper testifies that the optical detection approach must be divided into scattering style and transmission style via SNR Mathematic analysis, In addition, four corresponding technology principles are also analyzed in this paper. |
