Abstract
An optical position monitor for determining the position of a latch needle (104) in a knitting machine is provided that comprises: at least one fiducial (102) at a known fixed cation on the body of the latch needle; a fiducial imager that produces at least one optical image (262) of the at least one fiducial on at least one light sensitive surface (260) wherein the at least one optical image changes with changes in position of said at least one fiducial; and a controller that receives at least one signal responsive to the changes in the at least one image and uses the at least one signal to determine the position of the at least one fiducial (102) and thereby of the latch needle (104).
