Devices with micro-filters and micro-choppers for dynamic selection of colours and images

摘要

The radiation beam emitted by a polychromatic source of finite dimension is incident onto an array of microlenses which have the function of converging and dividing the beam into a plurality of microbeams directed towards a matrix containing coloured microfilters. Once the microfilters have been passed, the radiation reaches a matrix of microchoppers which can be selected independently from each other by a controller, for generating images.
