Wavelength-Encoded Tomography

摘要

Systems and methods for non-invasive optical imaging are provided. One or more time-lenses can be utilized to perform an optical Fourier transform, and the time-to-wavelength conversion can generate a wavelength-encoded image of optical scattering, analogous to optical coherence tomography. This optical Fourier transform provides improved axial resolution and simplifies digital signal processing after data acquisition.

1. An imaging system, comprising:
a sample platform; a photodetector; a linear frequency-shifted device positioned such that light from the sample passes through the linear frequency-shifted device before it reaches the photodetector; and a processing device in operable communication with the photodetector and configured to receive an output spectrum from the photodetector and realize a spatial-to-wavelength conversion, of the output spectrum, solely in the optical domain.
