High efficiency measurement of all orbital angular momentum modes in a light beam
Haad Yaqub Rathore, Mumtaz Sheikh, Usman Javid +2
We present an experimental demonstration of a Laguerre-Gauss (LG) spectrum measurement technique using variable focus lenses that is able to measure the strengths of all modes pres…
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…
A Technique to Measure Focal Length of a Lens with no Bulk Motion using Tunable Optics and Optical MEMS Technology
Syed Azer Reza, Arslan Anjum
This paper presents a motion-free technique for characterizing the focal length of any spherical convex or concave lens. The measurement system uses a Gaussian Beam from a Laser So…
