Abstract
Systems and methods for improved interferometric imaging are presented. One embodiment is a partial field frequency-domain interferometric imaging system in which a light beam is scanned in two directions across a sample and the light scattered from the object is collected using a spatially resolved detector. The light beam could illuminate a spot, a line or a two-dimensional area on the sample. Additional embodiments with applicability to partial field as well as other types of interferometric systems are also presented.
Claims3
An optical coherence tomography (OCT) device, comprising:
- a light source configured for generating a beam of light;
- a beam divider configured for directing a first portion of the beam of light into a reference arm and a second portion of the beam of light into a sample arm;
- a first scanner configured for receiving the second portion of the beam of light and configured for providing scanning along a first linear direction;
- a second scanner configured for receiving a first output from the first scanner and configured for providing scanning along a second linear direction at an acute angle to the first linear direction,
- wherein the first scanner and the second scanner have substantially the same scan speed;
- optics configured for directing a second output from the second scanner to one or more locations on a sample;
- a detector configured for receiving light returning from the sample and the first portion of the beam of light from the reference arm and generating signals in response thereto;
- and
- a processor configured for converting the signals into image data.
