Abstract
The polychromatic or monochromatic radiation beam emitted by a light source strikes an array of micro-filters which partially or totally transmit the light beam towards an array of micro-mirrors. The partially reflected beam comes back towards the first array of micro-filters and passes again through it until it reaches a viewer or a recording system or a screen. A relative movement between the two arrays of micro-filters and micro-mirrors enables static or animated images or colour strips selectable according to the needs to be generated.
