• This paper describes about a translucency measurement for translucent objects. The translucent objects in this paper are the object which translucency changes with deterioration of freshness like a squid mantle. The translucency measurements by the conventional method are affected by the thickness of the sample. We propose a new method that can solve this problem in this paper. In our method, we project a stripe pattern to the translucent object and quantify the translucency from its brightness of irradiated part and shielded part. The translucency measurement by our method has the merits that can reduce influence of changing of sample thickness and influence of fluctuation of irradiation light intensity. We tried a translucency measurement of translucent white resin samples. We made 12 kinds of plastic samples whose translucency and thickness were different, then measured those translucency by our method. Experimental results showed that we could measure translucency with reducing of the dependence of the thickness of sample and the intensity of irradiation light.
