VARIABLE WAVELENGTH LIGHT GENERATION DEVICE FOR LIGHT INTERFERENCE TOMOGRAPHY AND LIGHT INTERFERENCE TOMOGRAPHY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an OCT technology for enabling the tomographic observation of a hardly restrainable biological part and a tomographic observation technology omitting restraint in observation of a restrainable part for eliminating burden to a biological body.;SOLUTION: A variable wavelength light generation device (a variable wavelength light source) is used as a light source for the light interference tomography device. The variable wavelength light generation device is provided with a means capable of switching wavenumber stepwise. For example, the wavenumber can be switched at a wavenumber interval of ≤3.1×10^-4μm^-1 and a time interval of ≤530 μs within a wavenumber variable range of ≥4.7×10^-2μm^-1 and an outgoing radiation frequency range of ≤13 GHz.;COPYRIGHT: (C)2005,JPO&NCIPI
