LIGHT SHUTTER ARRAY ELEMENT, DRIVING METHOD THEREOF, PLZT FOR LIGHT SHUTTER ARRAY ELEMENT, AND METHOD OF PREVENTING VARIANCE IN THE TRANSMISSION LIGHT INTENSITY USING SAID PLZT

摘要

There is multiple separate electrode to be formed parallel to each other and be to be provided a predetermined voltage independently of one another in two or more column for a kind of light shutter array element, and public electrode so extends respectively to be arranged about the electrode demarcated, the direction that the mode of this branch electrode portions branching extends is inserted in during separated electrode respectively arranges, the electro-optic crystal substrate formed on individual electrode and public electrode surface. Substantially it is present in this distance to be different, with defined than from the adjacent individual electrode branches electrode section common electrode in the left and right sides and the branch electrode part. This method drives the fundamental characteristics of light shutter array element, thus when closed between pulse voltage, short-time pulse voltage is applied to electrode, i.e. total degree, always becomes constant with short-time pulse voltage using the driving pulse voltage, each unit time. In addition, the PLZT light shutter array elements of PLZT are to form sintered article average particle size to have region of the average grain sectional area less than 1/150 less than 5 ν m, which forms.
