Electro-Optical Sensing Apparatus And Method For Characterizing Free-Space Electromagnetic Radiation

View page
US Patent:
59528184, Sep 14, 1999
Filed:
Oct 25, 1996
Appl. No.:
8/739099
Inventors:
Louis Francis Libelo - Bethesda MD
Qi Wu - Troy NY
Assignee:
Rensselaer Polytechnic Institute - Troy NY
International Classification:
G01R 3100
US Classification:
324 96
Abstract:
Apparatus and methods for characterizing free-space electromagnetic energy, and in particular, apparatus/method suitable for real-time two-dimensional far-infrared imaging applications are presented. The sensing technique is based on a non-linear coupling between a low-frequency electric field and a laser beam in an electro-optic crystal. In addition to a pratical counter-propagating sensing technique, a co-linear approach is described which provides longer radiated field--optical beam interaction length, thereby making imaging applications practical.
