Abstract

We begin this issue by noting the celebration of a life of one of our Editorial Board Members, Harry K. Hammond, III, who passed away at age 97. Our first two articles are specifically on issues of color measurement. First James Gardner discusses “Spectral deconvolution applications for colorimetry.” Recently it has been suggested that deconvolution based on the Richardson‐Lucy algorithm is an effective method of reducing instrumental broadening effects in radiometric spectra. In this issue, Dr. Gardner applies the deconvolution technique to two specific applications in colorimetry: the calibration of the wavelength scale of a medium‐resolution array spectrometer and chromaticity measurement of light‐emitting diodes. He explains the numerous benefits that the spectral deconvolution has in these colorimetric applications. Portable spectrophotometers have become smaller and now easily held by hand when doing colorimetric measurements.
