Abstract:
1. An apparatus for imaging, comprising: a light source emitting a polarized light beam; an optical assembly including a light reflection surface, wherein the light beam from the light source is reflected by the light reflection surface to provide an evanescent field adjacent the light reflection surface, the light reflection surface being adapted to allow placing thereon a specimen array such that the specimen array in the evanescent field causes spatially distributed polarization changes in the cross-section of the light beam; a two-dimensional array detector positioned to detect the spatially distributed polarization changes caused by the specimen array; and a processor operably coupled to the two-dimensional array detector, the processor processing data from the two-dimensional array detector to provide a two-dimensional representation of the spatially distributed polarization changes occurring in the specimen array in real-time.
