154. A Flexible Bandpass Correction Method for Spectrometers
Published: Date unknown
Author: Yoshihiro Ohno
Abstract: An improved method for the correction of bandpass errors in spectrometers has been developed. This method is an improvement over the Stearns and Stearns method, which is limited in use to a triangular bandpass function and requires the bandwidth be ...

155. A Spectrally Tunable LED Sphere Source Enables Accurate Calibration of Tristimulus Colorimeters
Published: Date unknown
Authors: Irena Fryc, Steven W Brown, Yoshihiro Ohno
Abstract: The Four-Color Method (FCM) was developed to improve the accuracy of chromaticity measurements of various colors of a display. The method is valid for each type of display having similar spectra. To develop the Four-Color correction matrix, colorim ...

158. Color Rendering
Published: Date unknown
Author: Yoshihiro Ohno
Abstract: LED technologies are advancing at a swift pace and solid-state lighting (SSL) products are already introduced to the market and expected to grow rapidly. There is an increasing interest and concern in the color rendering properties of white SSL produ ...

160. Colorimetric Accuracies and Concerns in Spectroradiometry of LEDs
Published: Date unknown
Authors: C Jones, Yoshihiro Ohno
Abstract: LEDs are narrow-band emission sources and present special problems in colorimetric characterization. Chromaticity space is mapped using Gaussian spectral models to represent narrow-band emission sources. The Gaussian maps show that the spectral regi ...
