Colour density measurement of chromatograms - using opto-electric conversion and line-by-line resolution of video signal (HU 28.12.76)

The colour density of an image is measured by first converting the image into an electrical video signal. This is then resolved line-by-line; each line sampled and its signal level compared with standards. By digital conversion the signal level at each point (which is proportional to, the colour den...

Zusammenfassung:	The colour density of an image is measured by first converting the image into an electrical video signal. This is then resolved line-by-line; each line sampled and its signal level compared with standards. By digital conversion the signal level at each point (which is proportional to, the colour density) is counted up, displayed and printed. Used for the quantitative analysis of chromatograms, elphograms, autoradiogrames, photographic reproductions or copies. The analysis method is much more rapidly than the time-consuming use of densitometers.
