Abstract
A method and a device for monitoring the transparency of at least a portion of a preassembled laminated pane by analysis of the luminous intensity of the image of a test pattern viewed through the portion of the pane. The luminous intensity, picked up by a detector, of each point of the test pattern viewed through the pane is digitized to produce a number. The numbers obtained for the points of one same image are then averaged, the average obtained being compared with a previously determined theoretical value.
