    Abstract

    A novel digital laser lithographic system has been fabricated for storing optical information on the diffractive optical variable image device (DOVID). The digital input patterns on spatial light modulator (SLM) are imaged into the micro-images in the recording plane by a two tele-centric optical projection system with large reduction ratio. The micro-images are modulated by the interferential fringes with the spatial frequency range from 500~1200 lp/mm, which are generated by a grating interferential optical head in the lithographic system. The experimental results recorded on the photoresist plate show that the information storage density can be achieved over 3.7 Mbit/cm2 in one direction storage. The angle rotating multiplexing optical storage can be automatically realized by inputting multiple patterns needed to be stored, at the meantime, changing the direction and spatial frequency of interferential fringes. The optical storage lithographic system is useful in the fields of optical security and fabrication of diffraction optical variable image devices.
