Abstract:
Methods and apparatus are presented for obtaining high-resolution 3-D images of a sample over a range of wavelengths, optionally with polarisation-sensitive detection. In preferred embodiments a spectral domain OCT apparatus is used to sample the complex field of light reflected or scattered from a sample, providing full range imaging. In certain embodiments structured illumination is utilised to provide enhanced lateral resolution. In certain embodiments the resolution or depth of field of images is enhanced by digital refocusing or digital correction of aberrations in the sample. Individual sample volumes are imaged using single shot techniques, and larger volumes can be imaged by stitching together images of adjacent volumes. In preferred embodiments a 2-D lenslet array is used to sample the reflected or scattered light in the Fourier plane or the image plane, with the lenslet array suitably angled with respect to the dispersive axis of a wavelength dispersive element such that the resulting beamlets are dispersed onto unique sets of pixels of a 2-D sensor array.

Claim (Index 20):
A method for performing high resolution optical imaging of a sample, said method comprising the steps of:\n (i) illuminating, with a multi-wavelength optical beam, a volume of a sample to be imaged in three spatial dimensions; (ii) sampling, at a two-dimensional grid of sampling points, light reflected or scattered from the illuminated volume of said sample; (iii) simultaneously capturing phase and amplitude information over a range of wavelengths of the sampled reflected or scattered light, over said two-dimensional grid of sampling points; and (iv) processing the phase and amplitude information to construct, using digital refocusing, a three-dimensional image of an optical characteristic of said sample over said illuminated volume, wherein said optical characteristic is selected from the group consisting of phase, reflectivity, refractive index, refractive index changes and attenuation.
