Blackbody radiation inversion is a mathematical process for the determination of probability distribution of temperature from measured radiated power spectrum. In this paper a simple and stable blackbody radiation inversion is achieved by using an analytical function with three determinable parameters for temperature distribution. This inversion technique is used to invert the blackbody radiation field of the cosmic microwave background, the remnant radiation of the hot big bang, to infer the temperature distribution of the generating medium. The salient features of this distribution are investigated and analysis of this distribution predicts the presence of distortion in the cosmic microwave background spectrum.
黑体辐射反演是一种根据测量的辐射功率谱确定温度概率分布的数学过程。本文通过使用具有三个可确定温度分布参数的解析函数,实现了一种简单且稳定的黑体辐射反演。该反演技术用于反演宇宙微波背景(热大爆炸的残余辐射)的黑体辐射场,以推断产生介质的温度分布。研究了这种分布的显著特征,对该分布的分析预测了宇宙微波背景谱中存在畸变。
