Santos, Lucas Fugikawa [UNESP]Pereira, Clayton José [UNESP]2014-05-272014-05-272013-06-01Revista Brasileira de Ensino de Fisica, v. 35, n. 2, 2013.0102-4744http://hdl.handle.net/11449/75578In the present work, the basic concepts of radiometric, photometric and colorimetric calibration are presented, which were applied to three light-emitting diodes (LEDs) used to compose the different color sensations that the human eye perceives in the visible region of the electromagnetic spectrum. In this sense, an experimental setup comprising a LED drive circuit and a home-made integrating sphere was assembled for the initial radiometric and photometric calibration as well as to obtain a set of intensity and spectral combinations associated to different colorimetric CIE (Commission Internationale de l'Eclairage) coordinates. The reader can, therefore, understand, in a simple manner, the process of color composition inside a color monitor or display picture element (pixel ). © Sociedade Brasileira de Física.porCie coordinatesColor compositionFotometric calibrationLight-emitting diodesPicture elementsRadiometric calibrationArtigo10.1590/S1806-11172013000200014S1806-11172013000200014WOS:000321562100014Acesso aberto2-s2.0-848806813162-s2.0-84880681316.pdf0101178832675166
