Polarimetric imaging of amyloid

Micron, 2006
New developments in optical microscopy are discussed with relevance to the imaging of amyloid plaques that are pathognomonic of a variety of degenerative disorders. We present the results of linear birefringence, linear dichroism, and circular dichroism imaging of Congo red stained plaques ex vivo and in vitro.

Visible-regime polarimetric imager: a fully polarimetric, real-time imaging system

Applied Optics, 2003
A fully polarimetric optical camera system has been constructed to obtain polarimetric information simultaneously from four synchronized charge-coupled device imagers at video frame rates of 60 Hz and a resolution of 640 x 480 pixels. The imagers view the same scene along the same optical axis by means of a four-way beam-splitting prism similar to ones

Three-dimensional polarimetric integral imaging

Optics Letters, 2004
A three-dimensional (3D) polarimetric image sensing and display technique based on integral imaging is proposed. Three-dimensional polarization distribution of reflected light from a 3D object can be measured as elemental image arrays by a rotating linear polarizer.
