Abstract :
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.
