Abstract: A method for simulating the effects of optical power of a windshield on the image recording quality of a digital image recording device, in particular of a digital image recording device from an advanced driver-assistance system. It is based on adapted stochastic ray tracing method to simulate the effects of the optical distortions of a windshield on the image recording quality of a digital image recording device from a measured optical quality function of the windshields related to these optical distortions and an image of a landscape likely to be recorded by a digital image recording device. It provides a simulated image of said image as viewed through said windshield taking into account its intrinsic optical particularities. The method can be used in a process for evaluating the optical quality of windshields for a use with a digital image recording device.

Abstract: A method for measuring the optical quality of a given region of a glazing of a road or rail vehicle, the region being intended to be positioned in the optical path of an image-acquiring device, the measuring method being implemented by a measuring device including an emitter and a wavefront analyzer, the measuring method including emitting, with the emitter, a beam of light rays in the direction of the given region, analyzing, with the wavefront analyzer, the wavefront of the light rays transmitted by the given region, including generating a wavefront-error map, and determining, on the basis of the wavefront-error map, at least one optical-defect map, of any optical defects present in the region of the glazing.

Abstract: A method for measuring the optical quality of a delineated region of a glazing, the delineated region being intended to be placed in front of an acquiring or measuring device such as a camera. The method is particularly suitable for measuring the optical quality of a delineated region of a transportation-vehicle glazing, such as an airplane or automobile windshield, in front of which an optical device for recording images or a device for measuring the environment outside the vehicle is placed with a view to enabling operation of an advanced driver-assistance system of the vehicle.

Abstract: An optical device comprises a first polariscope and a set of first photodetectors and an optical retardation generator. The device is configured to analyze the quality of a glazing.
