OPTICAL COHERENCE TOMOGRAPHY

摘要

An optical coherence tomography apparatus according to an embodiment of the present invention comprises: a light source for generating a beam; a split prism which splits the beam passing through the split prism; a first line beam forming lens which is posited on the path of the beam split by the split prism and converts the beam into a line beam; a scan unit which is located at the back of the line beam forming lens and sends back a line beam generated by scanning at least one side of an object to be inspected which is located at one side; and a photographing unit for obtaining the tomographic information of the object to be inspected by photographing the line beam which returns from the scan unit through the split prism. According to the embodiment of the present invention, the object to be inspected is quickly scanned by converting the beam from the light source into a line beam, therefore, a time required for optical coherence tomography can be reduced compared to an existing optical coherence tomography time and a precise inspection can be performed.
