Abstract
A high-dispersion retroreflector includes filter glass transparent at least in near infra-red (NIR) wavelengths and configured to cause differential dispersion of incident broadband low-coherent light in the at least NIR wavelengths.
Claims15
A high-dispersion retroreflector comprising filter glass transparent at least in near infra-red (NIR) wavelengths and configured to cause differential dispersion of incident broadband low-coherent light in the at least NIR wavelengths.
A bulk filter glass differential dispersion interferometer assembly for extended depth imaging in optical coherence tomography (OCT), the interferometer assembly comprising an automated path length opto-mechanical assembly, which comprises:
- a first, fixed, retroreflector located at one end of an optical-path;
- and
- a second, adjustable, retroreflector co-located with a fixed high-dispersion retroreflector on a mount which is moveable to form an adjustable optical-path in the interferometer assembly,
- wherein the high-dispersion retroreflector comprises filter glass transparent at infra-red (IR) wavelengths and configured to cause differential dispersion at NIR wavelengths between broadband low-coherent incident light.
