MULTIPLIED SPECTRAL INTERFERENCE LIGHT COHERENCE TOMOGRAPHY

摘要

PROBLEM TO BE SOLVED: To realize a multiplied spectral interference light coherence tomography constituted so as to eliminate the delay of a measuring time due to high-order scanning and capable of performing the full range measurement of OCT including no complex conjugated image. SOLUTION: The multiplied spectral interference light coherence tomography comprises a first beam splitter 3 arranged on a light path 2 from a light source 1 to separate object light 4 and reference light 5; a galvanomirror 6 arranged on the light path of the reference light 5 to scan a measuring target 8 by the object light 4; a second beam splitter 10 arranged on the light path of the reference light 5; a first reference mirror 12 present on the light path of the first reference light 11 separated by the second beam splitter 10; a second reference mirror 15 present on the light path of the second reference light 13 separated by the second beam splitter 10; and a chopper 16 for permitting the first and second beams of reference light 11 and 13 to alternately pass.
