WIDEBAND OPTICAL SPLITTER, AND A MULTI WAVELENGTH BAND OPTICAL COHERENCE TOMOGRAPHY USING THE SAME FOR BEING OPERABLE IN A SIGNAL MODE IN A WIDEBAND WAVELENGTH DOMAIN AND HAVING A CONSTANT DISTRIBUTION RATE
PURPOSE: A wideband optical splitter and a multi wavelength band optical coherence tomography using the same are provided to obtain a sample image depending on a plurality of different wavelengths at the same time.;CONSTITUTION: A multi wavelength band optical coherence tomography using a wideband optical splitter (100) comprises the wideband optical splitter, a light source (210), a base end (220), a sample end (230), a spectrometer (240), a frame grabber, and a computer. The light source provides light to the wideband optical splitter. The light source divides into first and second light sources via the wideband optical splitter. The base end reflects the first light source by a reflecting mirror. The sample end reflects the second light source by a sample. The first and second light sources, which are reflected from the base end and the sample end, are combined via the wideband optical splitter again. The spectrometer obtains an interference fringe signal generated by a path difference between the first and second light source. The frame grabber transmits the interference fringe signal to the computer. The computer receives the interference fringe signal and converts it into an image.;COPYRIGHT KIPO 2013
