| 英文摘要 | a new method of single-track absolute position encoding based on spatial frequency of stripes is proposed. instead of using pseudorandom-sequence arranged stripes as in conventional situations, this kind of encoding method stores the location information in the frequency space of the stripes, which means the spatial frequency of stripes varies with position and indicates position. this encoding method has a strong fault-tolerant capability with single-stripe detecting errors. the method can be applied to absolute linear encoders, absolute photoelectric angle encoders or two-dimensional absolute linear encoders. the measuring apparatus includes a ccd image sensor and a microscope system, and the method of decoding this frequency code is based on fft algorithm. this method should be highly interesting for practical applications as an absolute position encoding method. |
