High-resolution electrooptic surface prism waveguide Deflector: an analysis.
A surface waveguide electrooptic deflector as described in the literature is analyzed in terms of a simple 2-D prism model. The model is treated by geometric as well as physical optics, and the far-field interference pattern is calculated. The results of this analysis are used to predict an upper limit to the ultimate resolvability of such a device. The maximum number of resolvable spots per centimeter of beamwidth, assuming +/-500-V drive, 50-mum prism aperture, and diffraction-limited operation, is shown to be on the order of 10(3). It is also shown that this ultimate resolution can be obtained only if the far-field interference pattern generated by the periodicity of the deflector array is overcome.
