TERAHERTZ TIME DOMAIN SPECTRAL APPATATUS AND IMAGE PROCESSING METHOD FOR REDUCING SAMPLING NUMBER

摘要

PURPOSE: A tera-hertz time domain spectral device and an image processing method are provided to obtain higher resolution of image with a smaller number of samples by employing compression sensing theory instead of radon transform. CONSTITUTION: A tera-hertz time domain spectral device(100) comprises an optical system and an adjustment system. The optical system employs tera-hertz beam as light source and forms a two-dimensional image using time domain. The adjustment system forms a mask(4) transforming Fourier domain on the optical system. The optical system restores the original two-dimensional object from one-dimension time data which is obtained by rotating the mask.
