A Light-Ray Approach to Fractional Fourier Optics
Éric Fogret, Pierre Pellat-Finet
A light ray in space is characterized by two vectors: (i) a transverse spatial-vector associated with the point where the ray intersects a given spherical cap; (ii) an angular-freq…
Double-Conjugation Law in Geometrical Coherent Imaging. Application to Gaussian Beams
Pierre Pellat-Finet
A centred system forms the coherent image of the optical field on a spherical cap, taken as an object, on another spherical cap, whose vertex and curvature center are the respectiv…
Effect of Diffraction on Wigner Distributions of Optical Fields and how to Use It in Optical Resonator Theory. III -- Ray Tracing in Resonators
Pierre Pellat-Finet, Éric Fogret
The third part of the paper is devoted to ray tracing in optical resonators. The employed method for dealing with the issue uses the elliptical or hyperbolic rotations that Wigner…
Effect of Diffraction on Wigner Distributions of Optical Fields and how to Use It in Optical Resonator Theory. II -- Unstable Resonators
Pierre Pellat-Finet, Éric Fogret
The second part of the article is devoted to field transfers by diffraction that are represented by fractional Fourier transformations whose orders are complex numbers. The corresp…
Effect of Diffraction on Wigner Distributions of Optical Fields and how to Use It in Optical Resonator Theory. I -- Stable Resonators and Gaussian Beams
Pierre Pellat-Finet, Éric Fogret
The first part of the paper is devoted to diffraction phenomena that can be expressed by fractional Fourier transforms whose orders are real numbers. According to a scalar theory,…
Coherent forward scattering of starlight by a cloud of atomic hydrogen
Frederic Zagury, Pierre Pellat-Finet
Theory predicts that a plane wave scattered by a thin slab of gas yields, in the forward direction and under specific circumstances, a larger irradiance than would be observed in t…
