Dr . Francis had an array of research interests including food pigments and colorimetry, thermal processing, post-harvest physiology of fruits and vegetables and technical methods for increasing the food supply.

In radiometry and colorimetry ( or color science more generally ), the spectral power distribution ( SPD ) of a light source is a measure of the power contributed by each frequency or color in a light source.
23.
Colorimetry techniques can be biased by color changes in test strips ( from airborne or finger borne contamination, perhaps ) or interference ( e . g ., tinting contaminants ) with light source or the light sensor.

On this basis the quantitative description of color mixture or colorimetry developed in the early 20th century, along with a series of increasingly sophisticated models of color space and color perception, such as the opponent process theory.

In the past, methods for the measurement of the anion gap consisted of colorimetry for [ HCO ] and [ Cl " ] as well as flame photometry for [ Na + ] and [ K + ].

On April 11, 2013, Bulb TV created by Canadian serial entrepreneur Evan Kosiner became the first broadcaster to provide a 4K linear channel and 2100 colorimetry ), and High Frame Rate ( up to 120 Hz ).

The ionized calcium can be determined directly by colorimetry, or it can be read off from nomograms, though the usefulness of the latter is limited when the pH and protein content of the plasma deviate widely from the normal.

According to Brian Markwalter, senior vice president, research and standards, CEA, " 861F " includes a number of noteworthy enhancements, including support for several new Ultra HD and widescreen video formats and additional colorimetry schemes .

"' Deane Brewster Judd "'( November 15, 1900 & ndash; October 15, 1972 ) was an American physicist who made important contributions to the fields of colorimetry, color discrimination, color order, and color vision.

The Colorimetry committee of the CIE considered MacAdam's proposal at its 14th Session in Brussels for use in situations where more perceptual uniformity was desired than the ( x, y ) chromaticity space, and officially adopted it as the standard UCS the next year.
