摘要	Advances in fine photoelectric displacement measurement technology have made image angular displacement measurement technology via imaging method a popular research topic; it is now easier than ever to realize small-scale high-resolution angular displacement measurement. This paper proposes a small-sized high-resolution image angular displacement measurement technique based on near-field image acquisition. A measuring mechanism based on the lensless near-field image acquisition is first established. Next, based on the error code problem, a space-value-based code value correction algorithm is proposed. Finally, the proposed device is validated on an experimental system. The proposed technology can achieve 21-bit resolution and 20.14" angle measurement accuracy. The results presented here may provide a workable foundation for further research on image-type fine photoelectric displacement measurement technology.
