    摘要: An imaging device uses a fiber optic faceplate (FOF) with a compressive sampling algorithm for the fluorescent imaging of a sample over an large field-of-view without the need for any lenses or mechanical scanning. The imaging device includes a sample holder configured to hold a sample and a prism or hemispherical glass surface disposed adjacent the sample holder on a side opposite the lower surface of the sample holder. A light source is configured to illuminate the sample via the prism or the hemispherical surface, wherein substantially all of the light is subject to total internal reflection at the lower surface of the sample holder. The FOF is disposed adjacent to the lower surface of the sample holder, the fiber optic array having an input side and an output side. The device includes an imaging sensor array disposed adjacent to the output side of the fiber optic array.

    摘要: A method determines the complex scattering function of a portion of a sample under analysis. The method includes providing a magnitude spectrum of a complex spatial Fourier transform of a complex intermediate function. The complex intermediate function is dependent on the complex scattering function of the sample. The magnitude spectrum is obtained from power spectrum data of frequency-domain optical coherence tomography of the sample. The method further includes providing an estimated phase term of the complex spatial Fourier transform. The method further includes multiplying the magnitude spectrum and the estimated phase term together to generate an estimated complex spatial Fourier transform. The method further includes calculating an inverse Fourier transform of the estimated complex spatial Fourier transform. The method further includes calculating an estimated intermediate function by applying at least one constraint to the inverse Fourier transform of the estimated complex spatial Fourier transform.
