Fermat Single Pixel Camera for Characterizing Optical Properties of Biological Tissues over the Visible to SWIR Spectral Range

We present Fermat single pixel camera for visible to SWIR biomedical imaging by encoding the spatial coordinate of the diffuse reflectance into different temporal modulation frequencies. The recovered reflectance spatial profile was then used to characterize the optical parameters of the specimen. The results from measurement on optical phantoms and biological tissues suggest Fermat single pixel camera can successfully quantify the optical properties over the visible to SWIR spectral range and may find valuable applications in imaging without a conventional camera.
