    Abstract: A device for inspecting a material (3) having a network with a regular pitch. The device comprises a means for moving the material (3), and at least one electronic camera (12) comprising a photosensitive point sensor and outputting a signal for an image formed on said sensor. During inspection, said material (3) moves through the optical field of the camera. The device further comprises a synchronising means (20) for synchronising the network mesh frequency factor and the imaging frequency of the camera (12).

    Abstract: Device for the optical determination of periodicities in textile bands, such as woven or knitted cloth, is provided with a light source for directing light radiation towards a band of cloth, a light detector for detecting light radiation reflected by the fabric and converting it into an electrical signal with varying intensity, and a signal processing circuit for determining periodicities related to the cloth and present in the electrical signal. Said signal processing circuit is constructed for counting threads or stitches and is provided with a high-frequency filter followed by a low-frequency filter for removing noise and low-frequency interference respectively from the said electrical signal and with an amplitude threshold stage with adjustable thresholds for assessing subsequent amplitudes. A measuring means is provided in said light source and light detector are combined into a single sensor (1) which is mounted next to one or two rollers (21, 22) mounted on a common spindle attached to a bracket (24), the roller(s) being pressed against the band of cloth (2). A tachometer (10) is coupled to one side of the common spindle to deliver a speed signal proportionate to the instantaneous roller speed, and an optical cell (25) is provided in one roller (21) to deliver a length pulse signal proportionate to the roller circumference.
