Abstract

A system includes a waveguide that guides a beam of radiation, a variable delay unit, and a polarization-dependent modulating unit. The variable delay unit modulates the refractive index in a region, and the waveguide makes a plurality of passes through the region. The polarization-dependent element compensates for birefringence associated with the beam of radiation and includes a polarization splitter and a plurality of modulating elements. The polarization splitter has a first arm and a second arm that each include modulation segments. The beam of radiation is split between the first arm and the second arm and recombined after traversing the modulation segments. The recombination of the beam generates a first polarized beam of radiation and a second polarized beam of radiation. The plurality of modulating elements apply a first and second modulation to the first polarized beam of radiation and the second polarized beam of radiation respectively.

Description

technical field [0001] Embodiments of the invention relate to the use of variable delay lines in high resolution optical coherence tomography. Background technique [0002] Optical coherence tomography (OCT) is a medical imaging technique that provides depth-resolved information with high axial resolution through a broadband light source and an interferometric detection system. It has found numerous applications ranging from ophthalmology and cardiology to gynecology and in vitro high-resolution studies of biological tissues. [0003] One of the elements in a Time Domain OCT (TD-OCT) system is a variable delay line, which can be used to perform a deep scan inside the sample. Several patents have described examples of delay lines used in OCT that can provide the necessary delay variation range at high scan speeds. For example, patent application number EP0831312 describes a device based on optical fibers and piezoelectric elements for use as a variable delay line in OCT. ...
