Title:
OPTICAL COHERENCE TOMOGRAPHY DEVICE AND OPTICAL COHERENCE TOMOGRAPHY METHOD
Document Type and Number:
WIPO Patent Application WO/2022/065305
Kind Code:
A1
Abstract:
Provided are: an optical coherence tomography device which, even in a portable form, is less likely to cause misalignment in tomographic images, and that is capable of performing tomographic imaging in a wide range at a time; and an optical coherence tomography method using the optical coherence tomography device. This optical coherence tomography device comprises an objective lens that focuses light from a light source onto a sample. The optical coherence tomography device performs tomographic imaging of the sample on the basis of interference of sample light, which is light reflected from the sample, and reference light, which is light reflected from a reference surface provided between the objective lens and the sample. Both the sample light and the reference light pass through the objective lens. The objective lens is an Fθ lens.
