Paperback. Condición: New. Print on Demand. This book investigates the human eye's capacity for distinguishing between colors, especially yellow and blue, and how the differences in human perception can lead to different photometric measurements. The author explores both icker and Lummer-Brodhun photometers and determines which…is best suited to take accurate photometric measurements. The author discusses the characteristics of a "normal" observer and how to select observers for accurate measurements. The author concludes that the icker photometer, used under specific conditions, provides the most certainty and reduces the labor needed to attain accurate results.
