Phasor field waves: A statistical treatment for the case of a partially coherent optical carrier
Syed Azer Reza, Sebastian Bauer, Andreas Velten
This paper presents a statistical treatment of phasor fields (P-fields) - a wave-like quantity denoting the slow temporal variations in time-averaged irradiance (which was recently…
Wave-like Properties of Phasor Fields: Experimental Demonstrations
Syed Azer Reza, Marco La Manna, Sebastian Bauer +1
Recently, an optical meta concept called the Phasor Field (P-Field) was proposed that yields great quality in the reconstruction of hidden objects imaged by non-line-of-sight (NLOS…
Virtual Wave Optics for Non-Line-of-Sight Imaging
Xiaochun Liu, Ibón Guillén, Marco La Manna +6
Non-Line-of-Sight (NLOS) imaging allows to observe objects partially or fully occluded from direct view, by analyzing indirect diffuse reflections off a secondary, relay surface. D…
A Physical Light Transport Model for Non-Line-of-Sight Imaging Applications
Syed Azer Reza, Marco La Manna, Andreas Velten
Non-line-of-sight (NLOS) imaging has recently attracted a lot of interest from the scientific community. The goal of this paper is to provide the basis for a comprehensive mathemat…
Power Transmittance of a Laterally Shifted Gaussian Beam through a Circular Aperture
Tariq Shamim Khwaja, Syed Azer Reza
Gaussian beams are often used in optical systems. The fundamental Gaussian TEM00 mode is the most common of the Gaussian modes present in various optical devices, systems and equip…
Calculation of Beam Propagation through a Defected or a Misaligned Two-Lens System
Tariq Shamim Khwaja, Syed Azer Reza
An inadvertent or unwanted angular deviation to a passing beam can be introduced by any single optical component within an optical system. The problem arises due to an imperfect ti…
