| 摘要 |
A low coherence interferometry Imaging system comprising a common-path Interferometer that is at least partially integrated as part of a planar lightwave circuit Is disclosed. Imaging systems in accordance with the present invention are Implemented in Integrated optics without the inclusion of highly wavelength-sensitive components, As a result, they exhibit less wavelength dependence than PLC-based Interferometers of the prior art. Further, the common-path interferometer arrangement of the present invention avoids polarization and wavelength dispersion effects that plague prior-art PLC-based interferometers. Still further, an integrated common-path Interferometer is smaller and less complex than other integrated interferometers, which makes It possible to Integrate multiple interferometers on a single chip, thereby enabling multi-signal systems, such as plane-wave parallel OCT systems. |
