Abstract
"Procedure and devices for the measurement of the optical defects of a body, in particular of flat glass", characterized by the application on the body to be examined of a narrow light beam formed by a target placed in the vicinity of this body, diaphragmized by a narrow central slit perpendicular to the direction of the analysis, placed in the vicinity of the main plane of exit of the objective, and illuminated by a slit-object of uniform luminous intensity of which it gives a real image, said slit-object being placed, on the axis, parallel to the diaphragm, oriented like it, and at least twice as wide as it, and by the reception of this light beam on a differential photoelectric cell placed in the plane of the aforementioned image and providing a signal of output function of the minute displacements that the body imposes on the image, perpendicular to the cleft, in relation to its reference position.
