Abstract

PURPOSE: To minimize damages of an electro-optic modulating plate even if electrical breakdown occurs in crystal and achieve the larger size and higher resolution of the modulating plate by arraying and fixing specific electro-optic crystals on a transparent substrate.
CONSTITUTION: A transparent electrode 14 is deposited and formed on one side of a transparent glass substrate 13. Over this are formed a glass solder layer 15, and further a NESA film 16 over the entire surface including the exposed portions of the layer 15 and electrode 14. Electro-optic crystals 18 of Bi12GeO20 of a size of about the picture element each having a transparent electrode 17 on one side are arrayed on the film 16, at an equal spacing, with the respective crystal bearings being aligned. These are then fixed by solder fusing. At the same time the electrode 17 are electrically connected to the electrode 14 via the film 16. Next, glass powder is filled in the spacing between each crystal 18 and with this glass powder as a mask, an Al vapor deposition metal mirror 19 is formed on the main surface of the crystals 18. The electro-optic modulating plate 12 having been removed of the glass powder and the electron beam scanning type electro-optic modulating plate 12 of reflection type are used for the electron beam scanning type electro-optical valve of reflection type
