listen to the pronunciation of fotometri, ışıkölçümü
Turkish - English
{i} photometry
the art of measuring the intensity of light
That branch of science which treats of the measurement of the intensity of light
The measurement of an object's brightness
The quantitative measurement of visible radiation from light sources
The accurate quantitative measurement of the amount of light received from an object or area
The measurement of various aspects of light, especially its intensity
measurement of the proterties of light (especially luminous intensity)
instrumental methods, including analytical methods, employing measurement of light intensity See telephotometer
The measurement of visible radiation
Branch of observational astronomy in which intensity measurements are made through each of a set of standard filters
Making measurements from images One example is creating a 3D scene description using stereo image analysis, and measuring the volume of an object in the model
The measurement of light quantities
The measurement of the properties of light, particularly (luminous) intensity
The measurement of the intensity and spectrum of light from stars
{i} measurement of the intensity of light (Physics); measurement of the brightness of stars (Astronomy)
The science and techniques involved in using photometers
The study of the measurement of the intensity of light
In astronomy, the measurement of the light emitting from astronomical objects, generally in the visible or infrared bands, in which a specific or general wavelength band is normally specified An excellent reference on this topic is Astronomical Photometry: A Guide, by C Sterken and J Manfroid (1992, Dordrecht: Kluwer Academic Publishers)
Precision measurement of the brightness, colour, and spectrum of stars and other celestial objects to obtain data on their structure, temperature, and composition. About 130 BC Hipparchus used a system that divided the stars into six magnitudes, from brightest to faintest. Beginning in the 17th century, use of the telescope led to the discovery of many fainter stars, and the scale was extended. The use of photographic and, since the 1940s, photoelectric equipment has vastly extended the sensitivity and wavelength range of astronomical photometry. The main (UBVRI) classification system uses wave bands in the ultraviolet, blue, visual, red, and infrared ranges. More elaborate systems can distinguish giant and dwarf stars, detect metals in stars, and determine surface gravity
