Description

technical field [0001] The invention belongs to the field of optical imaging, and in particular relates to a rotary optical tomographic imaging system and imaging method based on a linear array detector. Background technique [0002] With the development of optical technology and people's higher and higher requirements for image quality, various new imaging systems are also emerging. However, the current existing imaging methods mainly use the conical scanning optical tomography system for imaging. The conical scanning optical tomographic system mainly divides the image after the conical scanning through the modulation disc to obtain the tomographic signal. The structure of the system is relatively It is complex, requires more optical components, and is affected by the rotation eccentricity and defocusing of the optical system during conical scanning, which makes the algorithm and correction of the later image reconstruction difficult, and the stability of the system is poor...

However, the current existing imaging methods mainly use the conical scanning optical tomography system for imaging. The conical scanning optical tomographic system mainly divides the image after the conical scanning through the modulation disc to obtain the tomographic signal. The structure of the system is relatively It is complex, requires more optical components, and is affected by the rotation eccentricity and defocusing of the optical system during conical scanning, making the algorithm and correction difficult for later image reconstruction, and the stability of the system is poor

[0003] Due to the above defects, the existing imaging system using the conical scanning optical tomography system obviously cannot meet people's needs for imaging.
