Claim 6:
7. The imaging device of claim 4, wherein the one or more processors further operate to one or more of the following:
(i) use digitizers or modern digitizers that have one or more built-in Field Programmable Gate Arrays (“FPGAs”) for controlling data flow that are capable of OCT processing;
(ii) perform the OCT processing including one or more of the following: windowing of data, zero-padding, Fast Fourier Transform (FFT), magnitude calculation, and/or taking a logarithm of a result before issuance of a trigger pullback signal;
(iii) after an issuance of a trigger pullback signal, transfer raw data from the digitizer or the modern digitizer, and save and process the raw data at a lower rate than a rate at which the raw data was acquired; and/or
(iv) use a single channel for faster processing of data before issuance of a trigger pullback signal, and, after the issuance of the trigger pullback signal, use two detection channels.
