We present results of the application of a three-dimensional rigorous-
vector coupled-wave theory to the design of polarizing holographic opt
ical elements. Two different cases have been selected-giving rise to t
wo types of element, one of which is completely original. Experimental
realizations were performed, The recording material was dichromated g
elatin because of its outstanding performance related to diffraction e
fficiency. A fair agreement between the theoretical previsions and the
experimental results was achieved.
