Spectroradiometry, the measurement of absolute optical radiation at each wavelength, is applicable to a variety of settings, including measuring the spectral energy output of a lamp, LED display, or other light source to determination of the flux of sunlight reaching a forest floor or other scene.

Unlike other science research fields where it is possible to collect a sample and transport it to an instrument for measurement, characterizing spectral flux requires bringing the instrument to the measurement site for in-situ analysis.

Hi I am just getting started with Pix4D and I have been trying to purchase a radiometric calibration target with know albedo values to use for camera calibration.

I have visited a number of photography shops and they have no idea what I am talking about.Chronology is the science of locating historical events in time.It relies upon chronometry, which is also known as timekeeping, and historiography, which examines the writing of history and the use of historical methods.Consider, for example, the use of a timeline or sequence of events.It is also "the determination of the actual temporal sequence of past events".I have done search online and only found Pix4d or scholarly articles about radiometric targets.
