Resolution enhancement of total internal reflection microscopy via polarised scattering.

This paper presents a novel approach for enhancing the resolution of label-free total internal reflection microscopy. This method leverages the directional difference of the sample polar scattering by capturing microscopic images under the illumination of evanescent waves propagating in various directions. By computing the high-order autocorrelation accumulation of these images at different angles, we achieved a 1.

Fast Stray Light Performance Evaluation Based on BSDF and Radiative Transfer Theory.

Evaluating the stray light cancellation performance of an optical system is an essential step in the search for superior optical systems. However, the existing evaluation methods, such as the Monte Carlo method and the ray tracing method, suffer from the problems of vast arithmetic and cumbersome processes. In this paper, a method for a rapid stray light performance evaluation model and quantitatively determining high-magnitude stray light outside the field of view are proposed by adopting the radiative transfer theory based on the scattering property of the bidirectional scattering distribution function (BSDF).
