CMOS optical detector comprising a plurality of optical elements for device for monitoring parameters of moving yarn on textile machines

摘要

The invention relates to a CMOS optical detector (5) comprising a plurality of optical elements for a device for detecting parameters of moving yarn (2) or another linear textile formation on textile machines by means of perpendicular projection of yarn (2) onto individual optical elements (41, 42) of a sensor (4) with the aid of one source (3) of radiation. The optical elements (41, 42) of the sensor (4) are arranged in two parallel rows perpendicularly to the direction of the movement of the projection of yarn (2), each optical element (41, 42) produces at its output an analog signal corresponding to the intensity of its irradiation and each optical element is rectangular-shaped, whereby the individual optical elements (41) of the first row are oriented to have their longer sides in the direction of the movement of the projection of yarn (2), whereas the optical elements (42) of the second row are oriented to have their longer sides perpendicularly to the direction of the movement of the projection of yarn (2).
