Optical design and testing: introduction

Abstract

Optical design and testing has numerous applications in industrial, military, consumer, and medical settings. Assembling a complete imaging or nonimage optical system may require the integration of optics, mechatronics, lighting technology, optimization, ray tracing, aberration analysis, image processing, tolerance compensation, and display rendering. This issue features original research ranging from the optical design of image and nonimage optical stimuli for human perception, optics applications, bio-optics applications, 3D display, solar energy system, opto-mechatronics to novel imaging or nonimage modalities in visible and infrared spectral imaging, modulation transfer function measurement, and innovative interferometry.

Theory and algorithms of an efficient fringe analysis technology for automatic measurement applications

“…Such systems not only find applications in the classical fields of physics and engineering, but have expanded into many other disciplines, such as medicine, life sciences, biometry, communication technology, display of information in three dimensions, analog optical computation, machine vision, and photogrammetry, to mention only a few examples [4][5][6][7][8][9][10]. Figure 1 depicts a generic phase-based measurement system.…”

Design of multisegmented freeform lens for LED fishing/working lamp with high efficiency

“…Thus much electrical power is wasted [1,2]. Compared with these conventional lamps, LEDs have many advantages, such as high efficiency, a long lifetime, and fast response, together with climate resistance [3][4][5]. Thus, LEDs have been considered the most promising new lighting solution for a fishing fleet.…”
