编码成象技术用于提高针孔成象空间分辨率

IMPROVING SPACE RESOLUTION FOR PINHOLE IMAGING USING CODED IMAGING TECHNIQUE

本文采用编码成象技术处理针孔成象，提高其空间分辨率－ 采用反投影解码技术，对针孔成象的分辨率进行了计算，结果表明，可将１０μｍ 的针孔成象空间分辨率提高到３μｍ 左右－ 最后对字母“Ｃ”图象进行模拟计算，经反演后，可以得到与原图象相近的图象－

A coded imaging technique is used to treat a pinhole camera imaging in this paper in order to improve its space resolution.Using back project (BP) algorithm,the resolution for pinhole imaging is calculated.The results show that the resolution is increased from 10μm to 3μm.Finally,the image ‘C’ is simulated.After decoding,the image close to the original image is obtained.
