Abstract
1529208 Colour anomaloscopes AMERICAN OPTICAL CORP 22 Dec 1975 [2 Jan 1975] 52455/75 Heading G2J A colour anomaloscope comprises three lightemitting diodes 14, 16a, 16b which provide yellow, red and green luminance respectively together with means for directing the yellow luminance on to one part of a display field 12a and means for directing the red and green luminance on to an adjacent portion of the display field 12b, the luminance of the diodes 16a, 16b being inversely variable with respect to each other, and the luminance of the diode 14 also being controlled. As shown, an optical fibre assembly 20 transmits the light from the diodes to the display screen 12. A viewing system 10, 22 is provided.
