Dispersion modulation unit

摘要

In the present invention, there is disclosed a dispersion modulation unit consisting of a modulator (30) comprising at least one modulation filter (311), a modulation sensor (32), a modulation meter (320) and an output unit (80) connected by a signal line to said modulation sensor (32). The modulation filter (311) comprises as a first-degree dispersion modulator of the radiation components a modulated first-degree dispersion space (371) of solid or gaseous material. The modulated first-degree dispersion space (371) consisting of one or more dispersion subspaces (371a, 371b, 371c) has an input boundary (331) and an output boundary (341) connected by at least one dispersion curve (12) with a beam passing thereon. The modulator (30) is a modulator of the dispersion curve length (12) within the dispersion space (371). The modulation meter (320) is connected to both the input boundary (331) and output boundary (341) of the dispersion space (371). A modulation characteristic source (50) can be inserted between the modulation meter (320) and the output unit (80).
