Abstract

PURPOSE:To make it possible to measure the reflectivity of each color of a multi- color pattern within a single-scan range by spot light, by providing a method of calculating and outputting reflectivity based upon standard white color through previously-fixed sequential arithmetic. CONSTITUTION:Light from light source 10 is focused into spot light by focusing lens system 11 and a scan on the multi-color pattern of sample 4 arranged in a fixed scan area is taken by rotary reflex mirror 13. This reflected scan light is detected by focusing lens system 14 and converted into an electric signal, indicating a voltage level equivalent to the intensity of light, by photoelectric conversion part 15 before being sent to decoder 16. Decoder 16 digitizes sequentially a voltage level corresponding to the reflectivity of the color of each pattern by an electric signal from photoelectric conversion part 15 and after being stored temporarily in memory part 19, digitized signals are read out in sequence to calculate the reflectivity through fixed arithmetic processing.
