Precision Digital Tachometer

An entirely digital method of measuring angular speed, acceleration, and torque during transient characteristics is described. Diffraction gratings are used in an optical transducer, which is interfaced to a digital computer to process the data obtained and to provide a plot of the transient characteristics as functions of time.
