Abstract

Seven years ago, at the Houston Congress of IMEKO, I tried to show that optics will play a key role in measurement technology and informatics. Already the relatively short time since the Houston Congress has shown that optics gained on importance in many fields of measurement technology. The better understanding of diffraction and how to use optics below the diffraction limit has opened a number of new applications pushing the micro- miniaturization to levels thought a few years ago as physically impossible. At present one of the most fascinating subjects is the exploration of human visual mechanism and the application of the results of this research in different areas of photonics. The human visual system codes the retinal image into a number of sub-images, depending on brightness, color, movement sensation, etc. In electronic image processing we are just starting to learn how such coding could be performed. To understand how the visual image is processed is of utmost importance also in order to be able to present the measurement results on the display. This paper discusses color coding and measurement--how this branch of photonic measurements can gain from vision research. Further, the progress of standardization and measurement in photometry and radiometry is discussed.
