Abstract :
A converter-display device for optoelectronic imaging is considered in this work. The image scanning is carried out by modulated elastic waves traveling on a one-dimensional matrix of micromechanical strip waveguides. Waveguides are formed by dividing a silicon membrane on parallel strips, which are attached to a supporting silicon frame by their ends. When individual excitating of all waveguides using the appropriate piezoelectric transducers, the surface of the display device will contain N times M relief elements, where N - number of waveguides, M-number of separated bending deformations.
