DOI: 10.1093/mnras/stz2483
Abstract: Galaxies and galaxy groups located along the line of sight towards gravitationally lensed quasars produce high-order perturbations of the gravitational potential at the lens position. When these perturbation are too large, they can induce a… read more here.

DOI: 10.1117/1.oe.59.3.035109
Abstract: Abstract. During the production of a lens system, the assembling and manufacturing tolerances must be accurately controlled to ensure production efficiency. Thus, it is important to analyze and optimize the tolerance sensitivity of the lens… read more here.

DOI: 10.1364/ao.57.001127
Abstract: To reconstruct a wavefront in a non-coaxial lens system, we propose a diffraction model using the Fresnel integral. Inclination angle is the newly included parameter in the mathematical formula describing beam propagation. It is determined… read more here.

DOI: 10.3390/app8061006
Abstract: In this work we present an experimental proof of concept of a programmable optical zoom lens system with no moving parts that can form images with both positive and negative magnifications. Our system uses two… read more here.
