Paper Abstract

In hyperspectral imaging, a push broom method is very common. A sample is illuminated along a single line and reflected light is gathered from the same line. Effects of the illumination geometry on recorded intensity due to the colocation of illumination and data acquisition are investigated by simulating a push broom system geometry using Monte Carlo simulation. Multiple sets of realistic tissue optical parameters are used in the simulations, while illumination line width and its numerical aperture are varied. Values of recorded angular dependent radiance are compared, revealing observable effects of illumination line width. Some effects of illumination line numerical aperture that vanish at experimentally achievable illumination widths are also observed.
