<p>PURPOSE: To easily analyze distribution of function characteristic and surface structure with high contrast by exposing a layer or layer structure to be analyzed to a polarized light to excite a waveguide mode, and regenerating the horizontal difference of electrochemical characteristic of a sample by a load modulated electric field. CONSTITUTION: A gold electrode 2 is evaporated on the base bottom surface of a 90 deg. glass prism 1 functioning as a waveguide coupler, a nonlinear electrooptical active thin layer (for example, polymer film) 3 is formed thereon by spin coating followed by drying, and top electrodes 4A, 4B are evaporated thereon. A dc modulated electric field 9 of 100 V/μm at 110 deg.C higher than glass transition point Tg is loaded on a polarizing band 5 to polarize the light. A bang B is set as non-polarized contrast area, both bands A, B are photographed by a TV camera 6, the reflected light from a laser 7 is recorded as the function of incident angle, and the photographed 6 image is recorded on a magnetic tape. The modulated electric field 9 is loaded between the electrodes 2, 4 in this way, whereby the distribution of electroopitical effect of the band A can be observed.</p> |
