Four-color laser white illuminant demonstrating high color-rendering quality.
Solid-state lighting is currently based on light-emitting diodes (LEDs) and phosphors. Solid-state lighting based on lasers would offer significant advantages including high potential efficiencies at high current densities. Light emitted from lasers, however, has a much narrower spectral linewidth than light emitted from LEDs or phosphors. Therefore it is a common belief that white light produc...
متن کاملOptimization of Mixed White Light Color Rendering
A method is developed for optimization of color rendering for a light mixture. No derivatives of the rendering function are required. Constraints of correlated color temperature and approximate white can be incorporated. The method is developed based on the Complex Method with modification. It is first applicable for 3-colors light mixtures and then extended to a hierarchical and iterative stru...
متن کاملAsymmetric color matching: how color appearance depends on the illuminant.
We report the results of matching experiments designed to study the color appearance of objects rendered under different simulated illuminants on a CRT monitor. Subjects set asymmetric color matches between a standard object and a test object that were rendered under illuminants with different spectral power distributions. For any illuminant change, we found that the mapping between the cone co...
متن کاملEstimation of the Illuminant Color from Human Skin Color
Colour is an important and useful feature for object tracking and recognition in computer vision. However, it has the difficulty that the colour of the object changes if the illuminant colour changes. But under known illuminant colour it becomes a robust feature. There are more and more computer vision applications tracking humans, for example in interfaces for human computer interaction or aut...
متن کاملAll - Solid - State Four - Color Laser
This is the final report of a three-year, Laboratory Directed Research and Development (LDRD) project at Los Alamos National Laboratory (LANL). The goal of this project is to develop a solid state laser that produces visible output wavelengths, including the commercially compelling blue wavelength. The basic architecture of the device consists of a single-mode optical fiber doped with Pr3+ and ...
