troland
troland (ˈtrəʊlənd) na unit of light intensity, used to measure the amount of light reaching the retina in the eyetroland
troland[′trō·lənd] (optics) A unit of retinal illuminance, equal to the retinal illuminance produced by a surface whose luminance is one nit when the apparent area of the entrance pupil of the eye is 1 square millimeter. Also known as luxon; photon. troland
Tro·land (trō'lănd), L.T., U.S. physicist, 1889-1932. See: troland. tro·land (trō'lănd), A unit of visual stimulation at the retina equal to the illumination per square millimeter of pupil received from a surface of 1 lux brightness.Troland A unit of conventional retinal illuminance, which is used to correct photometric measurements of luminance that fall on the retina by scaling them to the effective pupil size.Troland, L.T., U.S. physicist, 1889-1932. troland - a unit of visual stimulation at the retina equal to the illumination per square millimeter of pupil received from a surface of 1 lux brightness.troland Unit of retinal illuminance equal to that produced when the luminance of the observed object is one candela per square metre seen through a pupil having an area of one square millimetre.
