ABSTRACT:
The invention provides a system for recording a datum onto a pixel on a light-sensitive sheet. The system essentially includes a light-emitting device and an interfering device. The interfering device has a plurality of gratings. According to the datum, at least one grating is selected from the plurality of gratings. Before the datum is recorded, the selected grating and the light-emitting device are both moved so as to align with the pixel. Then, the light-emitting device is driven to emit a light through the selected grating. Thereby, the datum is recorded on the pixel.
