摘要： The invention relates to a method for determining in a contactless manner the speed and/or length of a running thread (4) by means of an optical sensor device which is arranged in the run of the thread of a textile machine and which comprises at least one optical detector (6b). Said method comprises the following steps: passing the thread (4) through a measurement volume (5), generating a laser beam (2) by means of a laser source (1), collimating the laser beam (2) by means of an optical device (7), splitting the laser beam (2) into at least two partial beams (2a, 2b) by means of an optical splitting and guiding device (3) to split and guide the laser beam (2), guiding the two partial beams in such a manner that a partial beam is guided as a measurement beam (2a) onto the thread (4) in the measurement volume (5) and a shadow is cast thereon by the thread and the other partial beam is guided as a reference beam (2b) past the thread (4) and onto an optical detector (6b), superimposing the light of the measurement beam (2a) that is influenced and/or reflected by the thread (4) with the light of the reference beam (2b), electronically evaluating the measurement signals produced by the optical detector (6b) according to the laser Doppler anemometry method to determine the speed and/or the length of the running thread (4). The invention further relates to an arrangement for carrying out said method.

摘要： Für eine faseroptische Messvorrichtung mit einem optisch transparenten Sensorkopf (2), der mit zumindest einer Lichtsendefaser (4) und zumindest einer Lichtempfangsfaser (5) oder einem zweiten Lichtleiter verbunden ist, mit einer Lichtquelle, die direkt oder wirkungsmäßig mit der Lichteingangsfaser (5) verbunden ist, wobei die Lichtsendefaser (4) zumindest einen Teil des Lichtes der Lichtquelle in den Sensorkopf (2) leitet, welches an zumindest einer optischen Grenzschicht (7) des Sensorkopfes (2) mindestens einmal reflektierbar ist und in die Lichtempfangsfaser (5) auskoppelbar ist und mit einem Lichtdetektor verbunden ist, soll eine Lösung geschaffen werden, die sich durch eine weitgehende Unempfindlichkeit gegenüber elektromagnetischen Störungen und sehr geringe eigene Abstrahlungen auszeichnet und mit der die Messung mehrerer Parameter wie der Betauungszustand und die Temperatur mittels eines Sensors möglich ist. Dies wird dadurch erreicht, dass in dem Sensorkopf (2) zumindest ein temperaturabhängiger Lumineszenzfarbstoff (9) eingelagert ist, der mittels des in die Lichtsendefaser (4) eingekoppelten Lichtes anregbar ist, und eine Abklingzeit eines Lumineszenzlichtes des Lumineszenzfarbstoffs von dem Lichtdetektor messbar ist, wobei das Lumineszenzlicht mittels der Lichtempfangsfaser (5) an den Lichtdetektor übertragbar ist.

摘要： The invention relates to a method for non-contacting determination and/or increasing the yarn quality of a running thread (8) or the quality of a spool (20) which is obtained by winding up a running thread (8), or for a non-contacting determination of a possible breakage and/or jamming of a running thread (8), by means of a sensor device which is arranged at a spool point (6) in a textile machine, with a laser beam (3) being produced by a light source (2) and being split by means of an optical splitting and guidance device (4) for splitting and guidance of the laser beam (3) into at least two beam elements (5a, 5b), which are then guided such that they are joined together again at the thread (8), with the laser-doppler anemometry method being used to produce measurement signals from the light which is reflected from the thread (8), which measurement signals are evaluated electronically in order to determine the yarn quality of the running thread (8), with respect to its hairiness or in order to determine the spool quality or to determine thread breakage and/or thread jamming. The invention also relates to an arrangement which is suitable for carrying out this method.
