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.
Claims9
A bulk filter glass differential dispersion interferometer assembly for extended depth imaging in optical coherence tomography (OCT), the interferometer assembly comprising:
- a first retroreflector that is fixedly located at one end of an optical-path;
- and
- a second retroreflector and a high-dispersion retroreflector co-located on a mount, wherein the mount is moveable along the optical-path to form an adjustable optical-path between the first retroreflector and the second retroreflector in the interferometer assembly,
- wherein the high-dispersion retroreflector comprises a filter glass transparent at infra-red (IR) wavelengths and configured to cause differential dispersion at NIR wavelengths between broadband low-coherent incident light.
