WAVELENGTH DETECTOR AND AN OPTICAL COHERENCE TOMOGRAPHY DEVICE HAVING THE SAME

摘要

In a wavelength detector for detecting light of a particular wavelength and an optical coherence tomography device incorporating the same, the light of a particular wavelength is selectively detected in light supplied to the wavelength detector by using a flat plate member in which a single slit or a plurality of parallel slits has/have been placed, and the selected light and pixels associated with video images of a sample are mapped one-to-one such that the degree of resolution in the vertical direction of the sample can be improved. The wavelength of the light passing through the slit(s) is determined at an early stage by means of an optical spectrum analyser.
