Abstract
A note image acquiring system includes: a fiber laser, a fiber beam splitter, a fiber collimator, a laser beam expander, a lithium niobate intensity modulator array, a waveform generator, a signal amplifier, a polarization beam splitter, a quarter-wave plate, an imaging lens group, a line-array photosensitive chip, an image information processing module and an image combining module. The note image acquiring system can improve resolution of details of a note image without needing to increase the number of photosensitive chip units per unit length of a linear array image sensor.
