Embodiment 1

[0042] As shown in 4 , the wide-spectrum light source system 1 includes a wide-spectrum light source 8 , a source converging mirror 9 , a converging light source pinhole 10 and a light source collimating mirror 11 . The working process of the wide-spectrum light source system 1 is as follows: the wide-spectrum light source 8 in the wide-spectrum light source system 1 emits a wide-spectrum light beam, which is then converged by the light source converging mirror 9 and passed through the light source pinhole 10 for filtering, and then collimated by the light source collimating mirror 11. The parallel wide-spectrum light beams are irradiated onto the color filter system 2 .

[0043] The parallel light beam passes through the color filter system 2 and is filtered to retain the required wavelength and then uniformly irradiates the target 12. The beam is modulated by the target 12 to generate the desired target shape. The target 12 is fixed on the target positioning mechanism and preci...

Embodiment 2

[0048] In this embodiment, the high-speed scanning system 6 adopts a two-dimensional galvanometer system, and the color filter system 2 can adopt a grating diffraction monochromator, such as Figure 5 shown.

[0049] The wide-spectrum light source 8 emits a wide-spectrum light beam, which is converged by the light source converging mirror 9 and passed through the light source pinhole 10 for filtering, and then collimated by the light source collimating mirror 11 into a parallel wide-spectrum light beam, which irradiates the monochromator cylinder of the color filter system 2 The converging mirror 20 is unidirectionally converged onto the first filter slit 21 of the monochromator, and the light beam passes through the first filter slit 21 of the monochromator and is reflected by the first flat mirror 22 of the monochromator to the parabolic collimating mirror 23 of the monochromator Above, after being collimated by the monochromator parabolic collimating mirror 23 into a parall...
