Garant předmětu:

Josef PECÁK

Name of lecturer(s):

Josef PECÁK

Study Objectives:

Prakticky ověřit závislost Tch na žhavení vlákna žárovky, zvládnout techniku měření Tch a výpočtu miredových hodnot konverzních filtrů.

Mode of delivery:

Cvičení realizuje každý posluchač samostatně v kabinetu obrazové techniky, měření provádí pomocí přístrojového vybavení kabinetu. Termín cvičení vypíše vedoucí pedagog cvičení. Odevzdá se řádně vyplněná tabulka připojená k tomuto návodu.

Prerequisites and co-requisites:

Před vlastním provedením si každý posluchač prostuduje znovu celou problematiku týkající se měření a významu teploty chromatičnosti. Teoretickou přípravu zkontroluje vedoucí pedagog cvičení.

Recommended optional programme components

Course contents:

1/ Students determine the relationship of Tch of bulb burning fibres of selected light sources. The given light source burns at 30% and in gradual increasing three types of measuring devices are used for chromaticity. The measurement values of Tch are noted with the source input data onto a table. The average is determined from the received values. Maximum deviation from the means value for individual bulb Tch measurement data is determined.

2/ Using measuring instrumentsand sets of conversion filters, studentts determine experimental measurement values of transmission filters needed for chromaticity transmission established for various burning light sources for chromaticity „X“. /Value X is determined by the instructor individually for each student/ Experimental determinations of measured filter vlaues are noted onto the appropriate table row.

3/ As in point 2 above/ but with calculations only, the students determine for the Tch measures the conversion filter values needed for transmission to chromaticity „Y“ /Value Y is set by the instructor/. The calculated values are noted onto the table.

4/ Students determine a given unmarked filter, its trasnmittance values in measurements and using a given light source checks the independents of those values from the original chromaticity. The experimental measurent results are noted onto the table.

5/ Using a tri-band chromaticity measurment instrument, students determine, with a given bulb lighting, the correction and transmission filters needed for light correction to Tch = .......
