Abstract:
Presented is an optical coherence tomography system and method to increase imaging depth of optical coherence tomography (OCT) by selective amplification. In a swept-source OCT system with periodically linear wavenumber-vs-time characteristic, the signal in principle is summation of various sinusoidal signals with different frequencies. Each frequency component of the recorded signal carries reflectivity information for a certain depth of the analyzed object. At greater depth inside the analyzed object, the reflectivity information is generally weak due absorption and scattering. An analog or digital electronic circuit selectively filters and amplifies frequencies above some threshold, possibly up to another threshold. In this way, even small signals for relatively larger depths become detectable.

Claim (Index 1):
A swept-source optical coherence tomography system for recording sub-surface structure of an analyzed object, said optical coherence tomography system comprising:\n a swept light source configured for generating coherent light with a wavenumber varying with time; an interferometric system configured for splitting the generated light onto a reference arm and a sample arm, where the sample arm is for projecting light onto and receiving light from the analyzed object, and where the received light interferes with light returning from the reference arm to produce an interference signal; a photo-detector configured for recording a photo-detector signal in response to the interference signal; a signal processing unit configured for selectively amplifying a high wavenumber part of the recorded photo-detector signal and for generating a digitized signal from the selectively amplified photo-detector signal; and a data processing unit configured for calculation of at least one A scan from the digitized signal.
