Documenta Ophthalmologica, 1971
1. The question whether the rabbit's spectral sensitivity curve is based on one spectral system or based on more systems is investigated. 2. For this purpose two different methods have been applied. The first method is a photometric match technique that made use of moving contrasts.

Heterochromatic modulation photometry
Annual Meeting Optical Society of America, 1987Heterochromatic flicker photometry and minimally distinct border are two methods of estimating luminance for individual observers. We describe a method of obtaining luminance for heterochromatic lights presented in heterochromatic temporal alternation.

Applied Optics, 1971
A survey is given of the standards used in photometry and spectroradiometry. After an introduction in Sec. I, the candela and lumen standards are discussed in Sec. II. Some problems related to heterochromatic photometry and the changes in the IPTS are mentioned in Secs. II.B and II.C, respectively. Section III deals with standards for spectroradiometry-

Publisher Summary Photometry is widely used as a robust and versatile detection technique for the general analytical chemical literature and in some flow-injection analysis (FIA). Photometry is used to describe the assessment of the properties of light sources, such as radiation characteristics, color temperature, and color rendering index in color ...

American Journal of Physics, 1968
In order to reduce the confusion associated with many of the introductory treatments of photometry, it is suggested that initially the concepts of radiation transfer be introduced in terms of the more familiar units of radiometry. The conversion to photometric units can then be accomplished by a straightforward integration.

Icarus, 1986
The nonsynchronous rotational period and light curve for Phoebe are analyzed. The variations in CCD chip pixel response, the intensity of the images, the sky background level, and the atmospheric effects and color response of the detector are examined.

Strictly speaking, the projected images of all astronomical objects appear to possess a two-dimensional light distribution. In fact, due to the resolution con- straints of the earth atmosphere and of the observational equipments (telescopes as well as detectors), even point- like sources such as distant stars and extremely remote galaxies are spread ...
