Freeform optics constitutes a new technology that is currently driving substantial changes in
illumination design. It liberates designers and engineers from restrictions of optical surface …

Problems relating to diffractive computer optics, prospective diffractive-optical-element-
based (DOE-based) devices, and relevant information technologies are overviewed. Based …

In light science and applications, equally important roles are played by efficient light
emitters/detectors and by the optical elements responsible for light extraction and delivery …

This book presents an in-depth look at lenses free of spherical aberrations and is provided
using illustrative examples. Mathematical principles behind lenses free of spherical …

This reference book concentrates on microstructuring surfaces of optical materials with
directed fluxes of off-electrode plasma generated by high-voltage gas discharge and …

We develop a new ray map** approach to address the surface error and hot spot issues in
designing a freeform total internal reflection (TIR) lens for nonrotational uniform illumination …

Street lighting, which is one of the main players in energy waste and light pollution at night,
still faces the challenge of efficient lighting of roadways with curved and twisted shapes. To …

An integrated technology for coordinated design of all components of computer vision
systems (CVS) including optical system, lighting, hardware, and software, is proposed. Key …

Performing the laser processing of materials implies the importance of producing the desired
effect on local regions with a predetermined distribution of the beam-power density. The …

In order to solve the problem of high cost and low optical efficiency of current LED-based
headlamps, we introduced a new optical design approach for LED-based automotive …
