Abstract
Abstract Disclosed is a controller for a device which measures the length and diameter of a capillary of a spinneret. A first laser beam is positioned upon the capillary at a first angle with regard to the axis of the capillary and a second laser beam is positioned upon the capillary at a second angle with regard to the axis of the capillary. The beams are oscillated along the radius of the spinneret and the quantity of energy in the portion of each of the beams that pass through a capillary is sensed and the ratio of the sensed quantities of energy is determined. The radial oscillation of the beams results from operation of a galvanometer driven by a periodic signal having a voltage directly proportional to time. Thus, the first and second laser beams are oscillated so as to position the first laser beam at an angle with regard to the axis of the capillary that is proportional to the value of the voltage of the periodic signal driving the galvanometer. The ratio of the length and diameter of the capillary are mathematically correlated in terms of the relationship between the first and second angles and the ratio of the sensed quantities of energy. The mathematical correlation is then solved for the ratio of the length and diameter. The length of the capillary is then determined by multiplying the ratio of the length and diameter by a value reflective of the diameter of the capillary. The diameter of the capillary can be determined by solving a mathematical correlation of the diameter of the capillary in terms of the energy in the portion of the first beam passing through the capillary. According to this invention, the above described device is controlled so as to position the axis of the capillary coincident with the axis of the first laser beam by translating the rotating spinneret along the radius of the spinneret. Radial translation of the rotating spinneret is accomplished by the steps of generating a periodic sampling signal having a sampling period of predetermined duration, the sampling period corresponding in time to the maximum amplitude of the electrical signal representing the quantity of energy sensed in the portion of the first laser beam that passes through the capillary, sensing the value of the voltage of the periodic signal driving the galvanometer during the sampling period of the periodic sampling signal, generating an error signal reflective of the magnitude of the sensed voltage of the periodic signal during the sampling period of the periodic sampling signal, and radially translating the rotating spinneret at a rate reflective of the magnitude of the error signal.
