Abstract
The invention provides a method of using at least one sensor sensitive to infrared radiation for inspecting hollow, transparent or translucent articles at high temperature leaving various different forming cavities. The method includes a step of evaluating the level of infrared radiation from the articles coming from the forming cavities so as to adapt the exposure of the sensor in a subsequent step of inspecting the articles in such a manner as to cause the response of the sensor to be uniform regardless of the different cavities from which the articles come.
