System and method for optical coherence imaging
First Claim
1. A system for imaging at least a portion of a sample, comprising:
- a source arrangement generating at least one source electro-magnetic radiation forwarded to the sample and a reference; and
at least one detection arrangement including a plurality of detectors, at least one of the detectors capable of detecting a signal associated with a combination of at least one first electro-magnetic radiation received from the sample and at least one second electro-magnetic radiation received from the reference,wherein at least one particular detector of the detectors has a particular electrical integration time, wherein the at least one particular detector receives at least a portion of the signal for a time duration which has at least one first portion with at least one first power level greater than a predetermined threshold and at least one second portion immediately preceding or following the at least one first portion, the at least one second portion having at least one second power level less than the predetermined threshold, and wherein the at least one second portion is extended for a time period which is approximately at least 10% of the particular electrical integration time.

Abstract
A system and method for imaging of a sample, e.g., biological sample, are provided. In particular, at least one source electro-magnetic radiation forwarded to the sample and a reference may be generated. A plurality of detectors may be used, at least one of the detectors capable of detecting a signal associated with a combination of at least one first electro-magnetic radiation received from the sample and at least one second electro-magnetic radiation received from the reference. At least one particular detector may have a particular electrical integration time, and can receive at least a portion of the signal for a time duration which has a first portion with a first power level greater than a predetermined threshold and a second portion immediately preceding or following the first portion. The second portion may have a second power level that is less than the predetermined threshold, and extends for a time period which may be, e.g., approximately more than 10% of the particular electrical integration time.
