Abstract：
 The present invention relates to the optical coherent tomographic (OCT) imaging technology. Technologically, the present invention features that longitudinal resolution of OCT is raised through either utilziing dispersive element or blocking element to change the spectrum shape of input light source or utilizing one blocking element to change the spectrum shape of reference arm returned light. The present invention may be used for the OCT system with femoto second-level laser or SLD light source. The method is simple and may be used to raise the longitudinal resolution of OCT system for 20 microsecond to 14 microsecond.
