摘要： The process of the invention can be used for measuring angles characteristic of wheels of a motor vehicle, in which a light signal is produced by a light beam having a predetermined direction with respect to which an angle to be measured is measured, the angle being formed between the direction of the light beam and a reference axis of the goniometer which reference axis is perpendicular to the linear optical sensor. The linear optical sensor is constituted by a plurality of contiguous and aligned photo-sensitive elements, by means of which elements an image of the light signal can be read. The image is constituted by an ordered totality of intensities of incident radiations recorded on the photo-sensitive elements. Measurement of the angle is a direct function of a distance of the image from an origin for measurement of distances in longitudinal direction, which is defined by an intersection of the reference axis with a longitudinal axis of the sensor. The process comprises: reading of at least two images at known and different times; a comparison between the at least two images; data processing of data which emerges from the comparison by means of a converging process towards a result defining environmental disturbance, making the environmental disturbance distinguishable from the light signal and vice versa.

摘要： In a process for reading fractions of an interval between contiguous photo-sensitive elements in a linear optical sensor, of a type used in a goniometer, an angle measured is an angle formed with a reference axis of the goniometer, perpendicular to the linear optical sensor, by a light beam which is trained on the optical sensor by an optical device. The process comprises: a reading of a current image constituted by an ordered totality of intensities of incident radiations read on contiguous photosensitive elements; processing of data taken from the current image by means of a process which converges towards a result defining, with respect to an original determined by an intersection of the reference axis with an axis of the sensor, a distance d f a point of incidence on the sensor of an ideal optical axis of the light beam.
