Fig. 5.

B-scans of a mouse cornea; (a) original image obtained by applying NUDFT to 100% of the acquired non-linear wavenumber spectra; (b) CS reconstruction result with the NUDFT matrix from 37.5% of the acquired non-linear wavenumber spectra; (c) CS reconstruction result with the MNUDFT matrix from 37.5% of the acquired non-linear wavenumber spectra; (d), (e) and (f) are zoom in of the cyan rectangle areas in (a), (b) and (c) respectively. The scale bars represent 100μm. Image size in pixel is 700 × 1000.
