Memory for the color of non‐monochromatic lights [PDF]
Color Research & Application, 2006 AbstractThe aim of this work was to explore the limits of memory for the hue of coloured illumination using nonspectral colours. Eighty‐four undergraduate optometry students with normal colour vision as assessed by the Ishihara 38 plate test, were given 10 s to memorize the hue of a luminous surface (luminance 120 cd m−2), subtending 22 by 18 degrees ...

Degree of Diffraction for Monochromatic Light Beams [PDF]
ACTA PHOTONICA SINICA, 2015 A parameter, called the degree of diffraction, is defined to describe the diffractive spreading of a monochromatic light beam. The same as the degree of paraxiality that was introduced by Gawhary and Severini in Opt. Lett. 33, 1360 (2008), the degree of diffraction depends only on beam's angular spectrum.
