(a) Schematic diagram of the experimental arrangement ( coupled device camera, , computer). (b) An expanded view of the sample input (source) plane and exit (detection) plane showing the grid points in the plane. (c) A photograph of the exit face of the tissue sample. (d) Absorption and fluorescence spectra of the ICG dye solution in water. (e) A typical raw CCD image of the detection plane and how it is cropped and binned for analysis.
OPTICA generated fluorescence intensity distribution on (a) the detector and (b) the source planes. [(c) and (d)] Green’s function fits to the horizontal spatial profiles through the centers of intensity distributions in (a) and (b), respectively. (e) Cross sectional image at the plane. (f) Spatial profiles of the cross sectional image along the and directions shown by the white lines in (e).
Comparison of known positions and sizes of the target with OPTICA-determined values.
