Abstract
A novel dispersion optical system based on at least one grating is provided. The pitches of the grating are linearly modulated so that the incident light is dispersed into different monochromatic light at different diffraction angles. In such a system, an order sorting filter is not required to separate the light of a selected order from the rest of unwanted overlapped order.
