Abstract

Rapid scan optical delay techniques are used in parallel implementation of OCT using a detector and signal processing can be carried out using algorithms. Frequency encoded parallel OCT and multi-path, frequency encoded reference delay networks are used. A large number of frequency-correlated depth channels are used to acquire multiple depth scans of a sample. A different frequency shift (Doppler shift) on each different path length, or delay, is used to obtain simultaneous respective signals and, thus, information about the sample, from different depths in the sample. Reference delay line functions are obtained using bulk optics, integrated optics and fiber optics.
