Abstract

PURPOSE: To achieve the improvement in performance by additionally providing a micro-channel plate having light amplifying action to the incident side of light information.
CONSTITUTION: The micro-channel plate enclosed by the light transmittable glass case 8 having been coated with the micro-channel group 6 formed by arraying the channels comprising providing high resistance layers on the inside surface of glass pipes or ceramic pipes and deposited with the material emitting photo electrons when radiated with light such as of Ge, Al2O3, etc, on the portions where the secondary electrons of the inside surface arrive, is additionally provided to the transparent electrode 1, on the side where input light information 9 enters, of the space lignt modulating element. Then, as the light imformation 9 enters, the micro-channel group 6 releases photo electrons, by which a fluorescent surface 7 is selectively emitted of light and this light enters a photo transfer layer 3 and is stored in an electro-optic effect layer 4. Hence, even when the sensitivity of the space light modulating element is low or when the light information 9 is slight, the sure writing and reading-out of information is made possible.
