Problems solved by technology

[0022] The limited imaging speed, limited imaging range, increased sensitivity loss with imaging depth, and working in a substantially fixed imaging mode of previous OCT techniques lead to compromises in OCT imaging performance and limit the application of OCT techniques

Abstract

An agile optical imaging system for optical coherence tomography imaging using a tunable source comprising a wavelength tunable VCL laser is disclosed. The tunable source has long coherence length and is capable of high sweep repetition rate, as well as changing the sweep trajectory, sweep speed, sweep repetition rate, sweep linearity, and emission wavelength range on the fly to support multiple modes of OCT imaging. The imaging system also offers new enhanced dynamic range imaging capability for accommodating bright reflections. Multiscale imaging capability allows measurement over orders of magnitude dimensional scales. The imaging system and methods for generating the waveforms to drive the tunable laser in flexible and agile modes of operation are also described.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of now-pending US Provisional Patent Application No. 61 / 676,876, filed July 27, 2012. The disclosure and entire teaching of US Provisional Patent Application 61 / 676,876 is incorporated herein by reference. technical field [0003] The present invention relates to the field of optical coherence tomography (Optical Coherence Tomography, OCT) imaging. Background technique [0004] Optical coherence tomography (OCT) is a non-invasive interferometric optical imaging technique that produces micron-resolution 2D and 3D images of tissue and other scattering or reflective materials. OCT is often used in biomedical imaging or material inspection. First demonstrated in 1991 for imaging of the human eye and coronary arteries, OCT has thus been established as the clinical standard for diagnosing and monitoring treatment of eye diseases. OCT is also used for intravascular imaging of platelets t...
