Báo cáo hóa học: " Research Article Point Spread Function Estimation for a Terahertz Imaging System" pot

... Gaussian beams. 4.2. Validation. As a validation test, we use both estimated point spread functions, obtained on the basis of two phantom data, and the direct estimation of the point spread function ... of a point- source approximation will face the challenge of balancing resolution ag ainst sensitivity. Examples of approximations for point sources include standard stars...
