Abstract

PURPOSE:To prevent an electric noise from mixing in, and also to realize microminiaturization of a converter, by suitably selecting an array of a light transmission body, and an incident direction of a stimulating light beam and a transmission light beam, and executing D/A or A/D conversion. CONSTITUTION:Rectangular parallelepipedlike optical transmission bodies 1a, 1b...1g consisting of photosensitive glass are inserted in series into a common optical path 22'. Each light transmission body 1a, 1b...1g makes binary-coded ultraviolet information V1, V2...Vn incident to separate optical paths 3a, 3b...3g connected to each light transmission body 1a, 1b...1g so as to meet at right angles with the common optical path 22'. According to this constitution, a logarithm of intensity of a visible light beam L which has been incident from an optical path 2 receives modulation being proportional to digital information V1, V2...Vn, is outputted to an optical path 2', and digital signals V1, V2...Vn by ultraviolet rays are converted to an analog L' of the visible light beam.
