This paper presents a simple, cost-efficient, and highly stable quantitative differential phase-
contrast (PC) microscopy based on Talbot interferometry. The proposed system is composed …

Surface microtopography measurement (eg, form, waviness, roughness) is a precondition to
assess the surface quality of technical components with regard to their applications. Laser …

Golf ball-like particles having a number of dimples on their spherical surfaces were prepared
by a combined method of heterocoagulation between hard polymer particles and soft …

Based on planar grating Fresnel diffraction theory, the correlation between Talbot positive
self-image and negative self-image for spherical wave illuminating on planar grating is …

摘要从理论和实验两方面讨论了方形孔径微透镜阵列的泰伯效应, 利用传递函数法分析了该阵列
的菲涅耳衍射区的光场复振幅分布, 讨论了泰伯像成像的条件. 实验中, 在特定位置处可观察到三 …

Since the random edges of practically manufactured grating can be described by the self-
affine fractal model, this paper investigates theoretically Fresnel diffraction of grating with …

The self-imaging phenomenon, or Talbot effect, consists of the replication of a periodic
structure at certain distances along the optical axis when an object is illuminated with …

Linear gratings and circular gratings are most commonly used in the applications of Talbot
effect, due to their simple patterns and ease of analysis of Moiré fringes. In the present …

In this paper, we propose a method for measuring the micro-angle based on the 2D grating
Talbot effect to generate the moiré fringe period. Firstly, the measurement principle of the …

In the present work, we study the Talbot e ect under selective reflection of probe radiation at
the interface between a dielectric and a layer of resonant atoms, in which a Raman grating is …
