On calculating metamer sets for spectrally tunable LED illuminators.
Solid state lighting is becoming a popular light source for color vision experiments. One of the advantages of light emitting diodes (LEDs) is the possibility to shape the target light spectrum according to the experimenter's needs. In this paper, we present a method for creating metameric lights with an LED-based spectrally tunable illuminator. The equipment we use consists of six Gamma Scient...
متن کاملMetamer Crossovers of Infinite Metamer Sets
For a fixed illuminant and observer there is a whole set of reflectances resulting in an identical response, these reflectances are called metamers. It can be shown analytically that all reflectances in each such set must intersect at least three times. There is a large amount of literature arguing about the properties of these sets, in particular about the position and number of nodes of inter...
متن کاملGeneralized Extremal Optimization Algorithm to design a LED-based spectrally tunable light source for Star Simulation
An Autonomous Star Tracker (AST) has been designed and is being constructed at National Institute for Space Research (INPE). In order to calibrate and characterize the AST a sophisticated infrastructure of tests is required. This infrastructure, composed of several instruments, has included one Star Simulator (SS). The simulator has also been designed and constructed at INPE. The SS is basicall...
متن کاملColor Correction by Calculating a Metamer Boundary Descriptor
Color correction describes the transformation process between device RGB values and CIEXYZ resp. CIELab values. In every metamer color reproduction system this is the first color transformation after image acquisition. In general, this mapping is not unique since the spectral sensitivities of most of the devices do not satisfy the Luther condition and because the acquisition and viewing light s...
متن کاملSpectrally Tunable Sources for Advanced Radiometric Applications
A common radiometric platform for the development of application-specific metrics to quantify the performance of sensors and systems is described. Using this platform, sensor and system performance may be quantified in terms of the accuracy of measurements of standardized sets of source distributions. The prototype platform consists of spectrally programmable light sources that can generate com...
