Abstract
An array of M.times.N electrodisplacive actuated mirrors for use in an optical projection system is assembled by way of: (a) preparing two identical ceramic wafers; (b) forming M identical trenches thereon; (c) interlocking and bonding together to form a ceramic block; (d) forming a composite ceramic structure from the ceramic block by polishing the top and bottom surfaces thereof; (e) providing M.times.N signal electrodes and M+1 bias electrodes; (f) mounting on an active matrix to thereby form an array of M.times.N actuators; (g) placing M+1 photoresistive segments; (h) preparing places for attaching platforms, to be formed thereon a light reflecting layer; (i) forming a light reflecting layer; (j) pattering the light reflecting layer, including the platform, into an array of M.times.N mirrors; and (k) removing the M+1 photoresistive segments to thereby form the array of M.times.N electrodisplacive actuated mirrors.
