Abstract:
    A degenerate pseudo-random rotation sensor is provided in the invention. The code disc is made up of a clock code track and a pseudo code track which is encoded in the whole circle by the binary pseudo-random sequence. It is: (1) it expresses the whole circle is divided into m parts by the closed ring composed by the m binary code sequence, the m is the positive integer; (2) the angle position code is the series of n binary code, the n is bigger than 4; (3) the m is less than 2n; (4) the angle position code is the only and the m different angle position codes are correspondence with the m angle position in the whole circle. The invention can save the space and the time by using the topological diagram to encode the circle pseudo-randomly. The photoelectric rotation sensor can provide the digital rotary parameter of the position, the speed and the direction at the same time; also it can keep the data reliability as the absolute formula.
