Claims11
An optical coherence tomography (OCT) system configured to interrogate a sample, the OCT system comprising:
- at least one light source, and a reference arm light guiding system;
- wherein:
- the light source is configured to form a light beam;
- the reference arm comprises a multi-pass dispersion compensation cell and a mirror;
- the multi-pass dispersion compensation cell comprises a transparent prism, wherein two highly reflective surfaces of the prism are highly reflective to the light beam, wherein the transparent prism is configured so that the light beam enters the multi-pass dispersion compensation cell through a first transparent surface and the light beam exits from a second transparent surface;
- and
- the multi-pass dispersion compensation cell is configured to extend a path length of the light beam that enters the multi-pass dispersion compensation cell based on reflecting the light beam back and forth on the two highly reflective surfaces of the prism before the light beam exits the multi-pass dispersion compensation cell.
