Gloss measurements of flat and smooth surfaces


We have succeeded in building a new type of glossmeter with the following attributes: the option to accurately check the gloss properties of non-flat surfaces, such as those of fruits and vegetables; the ability to change the angle of illumination; the use of a helium-neon laser for illumination; the ability to collect data from a three-dimensional body by scattered light beams in real time, special software for data analysis capable of computing the effects of reflected light from a curved surface. In other words, the computer gives a single number representing the gloss of the curved surface, by using appropriate analysis techniques.
