TISSUE MEASURING OPTICAL INTERFERENCE TOMOGRAPHY-USE LIGHT PRODUCING DEVICE AND TISSUE MEASURING OPTICAL INTERFERENCE TOMOGRAPHY DEVICE

摘要

It has strongly been desired that the shape of the entire vicinity of a corner angle consisting of a sclera, a cornea and an iris be sufficiently measured with a clear tomographic image. A variable-wavelength light producing device (11), which can emit a light having a wavelength in a 1.53-1.85 μm region while switching it, has the interference-capable distance of the light in the air of at least 1.4 mm, and can discontinuously switch the wavelength of the light at a wave number interval of up to 1.2×10-3 μm-1, is used to constitute an eye measuring optical interference tomographic device.
