Abstract
An optically computed optical coherence tomography (OC-OCT) technology is disclosed. The OC-OCT system performs depth resolved imaging by computing the Fourier transform of the interferometric spectra optically. The OC-OCT system modulates the interferometric spectra with Fourier basis function projected to a spatial light modulator and detects the modulated signal without spectral discrimination. The optical computation strategy enables volumetric OCT imaging without performing mechanical scanning and without the need for Fourier transform in a computer. OC-OCT performs Fourier transform signal processing optically, without the need of mechanical scanning, and before data acquisition unlike traditional OCT methods and systems. The scan-less OCT imaging is achieved through the use of spatial light modulator (SLM) that precisely manipulates light wave to generate output with desired amplitude and phase.
