[Abstract]:Spectrum coded imaging technology is a new biological tissue imaging technology which uses grating coding in transverse position. In this technique, a grating and a focusing lens are used to generate spectral coding lines on the sample, and a line image can be obtained without additional scanning. Combined with frequency domain interference technology, three-dimensional images can be obtained by adding slow line scanning, which is of great practical value in endoscopy imaging. Based on the analysis of the basic principle of spectrum coding imaging technology, the main performance parameters are derived. Through the imaging of the resolution test target, the factors affecting the transverse resolution are verified and analyzed. The results show that the resolution in the direction of the coding line is inversely proportional to the diameter of the incident spot and proportional to the focal length, and the resolution perpendicular to the direction of the coding line is weaker than that in the direction of the coding line. Finally, the onion samples are imaged to verify the feasibility of spectrum coding imaging technology.
