In this paper a wavelength-multiplexing based super-resolving concept is presented to allow high resolution imaging through blood. We use temporally pulsed and spectrally wide-band laser while at its output we have special grating and a spatial 2-D transmission mask allowing to project wavelengths’ dependent high-resolution spatial orthogonal encoding patterns (different spatial patterns for each wavelength). The ballistic photons of the short temporal pulses allow the high-resolution encoding pattern to reach the inspected object through the scattering blood medium without being spatially blurred. The light is intentionally collected via low resolution optics. The high-resolution reconstruction can be obtained digitally by post processing or optically by passing the collected low-resolution data through a similar grating and 2-D mask which do an all-optical decoding. After summing all the images together, the super-resolved reconstruction through the highly scattering blood medium is formed.
