CONTENT INSPECTION METHOD AND INSPECTION DEVICE OF PACKAGE PRODUCT

摘要

To construct a content inspection system of a package product which can perform accurate inspection of a content and which is inexpensive and small in scale.SOLUTION: A package product having a content contained in a packaging material transmitting far-infrared light, the package product being at a first temperature uniformly, is irradiated with far-infrared light having radiation intensity based on a second temperature different from the first temperature. Far-infrared light radiated from the package product is photographed by a far-infrared camera. Inspection of the content is performed on the basis of an image showing spatial intensity distribution of the photographed far-infrared light.SELECTED DRAWING: Figure 1
