Embodiment 1
Fig. 1 is the structural schematic diagram of grating inclination of wave front dispersion compensation device embodiment 1 of the present invention, with Fig. 1, Fig. 3 and Fig. 4
Illustrate application method of the present invention in inclination of wave front acquisition technology.As seen from the figure, grating inclination of wave front dispersion compensation of the present invention
Device, including the first balzed grating, 1, Offner optical system and the second balzed grating, 4, the Offner optical system is by recessed
Face reflecting mirror 2 and convex reflecting mirror 3 are constituted, the grating constant phase of the grating constant of the second balzed grating, 4 and the first balzed grating, 1
Deng the radius of curvature of the concave mirror 2 is 2 times of the radius of curvature of the convex reflecting mirror 3, and the concave surface
The center of curvature of reflecting mirror 2 and the center of curvature of the convex reflecting mirror 3 coincide with 1: 200；Incident light 110 is through described
After first balzed grating, 1 diffraction, the first diffraction light 120 of the first balzed grating, 1 output is incident on the concave mirror 2,
The convex reflecting mirror 3 is incident on after 2 first reflection of concave mirror, through 3 second secondary reflection of convex reflecting mirror
The third time reflected light 130 through the concave mirror 2 reaches the first balzed grating, 1, the third secondary reflection again afterwards
Formation second diffraction light 140 of the light 130 after 1 diffraction of the first balzed grating, second diffraction light 140 is along the incident light
110 opposite directions are emitted to second balzed grating, 4, and third diffraction light is formed after 4 diffraction of the second balzed grating,
150, it is working face 5 along 150 direction of third diffraction light, the working face 5 is parallel with the grating face of second balzed grating, 4；
The incident light 110 is incident upon the incidence angle 401 of the first balzed grating, 1 and the second diffraction light 140 is incident upon
The incidence angle 402 of two balzed grating,s 4 is equal；The vertical range of the working face 5 and the second balzed grating, 4 is first to glare
Twice of vertical range between 3 center point of curvature 200 of grid 1 and the convex reflecting mirror.The concave surface in this embodiment
Reflecting mirror and convex reflecting mirror are spherical reflector.
Incident beam 110, central wavelength λ0, spectral width is Δ λ, no inclination of wave front.Second diffracted beam 140 obtains
Time domain and spatial dispersion precompensation.The light beam pass through the second balzed grating, diffraction, at working face 5 become non-dispersive (time and
Space is without broadening) third diffracted beam 150, third diffracted beam 150 has certain inclination of wave front.
Beam center light is chosen below carries out grating dispersion analytic explanation the working principle of the invention:
As shown in figure 3, incident beam central ray 110 contains all wavelengths ingredient in the spectral region of tested light beam, with
The incidence angle 401 of first time diffraction is incident from the point 201 on the first balzed grating, after the first balzed grating, diffraction, middle cardiac wave
Long λ0Light 120 is emitted at an angle, and the light 121 for deviateing central wavelength d λ is emitted at different angles, they are through recessed
The Offner optical system of face reflecting mirror and convex reflecting mirror composition, central wavelength light 130 are again incident at a certain angle
It is transmitted after first balzed grating, along 140 directions, the light 131 for deviateing central wavelength is again incident on the first glittering with different angle
It is transmitted after grating along 141 directions.According to Offner optical system characteristics, light 120 is parallel with 130, and light 121 is parallel with 131,
According to grating formula, light 140 and 141 is parallel with light 110 respectively, and is spatially separating.According to geometrical relationship and optical grating diffraction
Characteristic calculates separately 140 λ of light0With 141 (λ0+ d λ) time bias and spatial offset amount.
Time bias, i.e., 141 opposite 140 beam Propagation direction time delay, with wavelength variation relation such as
Following formula:
Wherein, c is the light velocity, d1It is the grating constant of the first balzed grating, Lgg’It is anti-for the first balzed grating, and the convex surface
Twice for penetrating the vertical range 301 between mirror curvature central point 200, γ are the incidence angles 401 of first time diffraction, and t is second to spread out
Penetrate the time needed for light group is transferred to some section vertical with the direction of propagation.As can be seen that the pulse propagation that wavelength is longer
It obtains faster.
Spatial offset amount, i.e., 141 is as follows with respect to the relationship of 140 distance and wavelength:
Wherein, Div is the distance that light deviates incident ray 110.As can be seen that pulse and incident ray that wavelength is longer
Apart from smaller.
The diffraction of Fig. 4 expression parallelism of raster pair light beam.Space pre-compensates for light beam with the incidence angle 402 of third time diffraction
Incident second balzed grating, 4, according to light path principle, the different wave length light group issued from point 203, central wavelength lambda0Light
150 are propagated with certain incident angles to the second balzed grating, 4, diffracted ray along 140 ' directions, deviate central wavelength d λ's
Light 151 is with different incident angles to the second balzed grating, and second of diffracted ray is propagated along 141 ' directions, due to 140 '
It is consistent with the 141 ' directions of propagation.According to geometrical relationship and diffraction properties, these incident ray groups pass through the second balzed grating, 4
After diffraction, spatial offset occurs between different wave length light, i.e., 141 ' opposite 140 ' distance is as follows with the relationship of wavelength:
Wherein, d2It is grating constant, LgcIt is the vertical wheelbase in working face position 5 and the second balzed grating, face from 302, Div ' be
The distance between emergent ray and the 203 to the second balzed grating, upright projection position 204 of point, γ ' is the incidence of third time diffraction
Angle 402.As can be seen that from the light group that point 203 is launched after 4 diffraction of the second balzed grating, the longer pulse of wavelength and 204
The distance of point is bigger.
The relationship of time delay and wavelength of the light group after the second balzed grating, 4 is calculated according to the following formula simultaneously:
Wherein, t ' is to be transferred to from 203 points and the time needed for some vertical plane of 140 ' transmission directions.As can be seen that from
The light group that point 203 is launched after the second balzed grating, diffraction, transmit slower by the longer pulse of wavelength.
According to light path principle, the light group that will obtain space-time precompensation converges in a little 203, and the time is without exhibition
Width allows 140 and 140 ' light simultaneously, 141 be overlapped on the space-time of 141 ' light, need to meet following relationship:
From the above equation, we can see that the formula establishment condition is unrelated with light incoming position, so expanding to entire incident beam bore
Interior, remaining non-central light is all satisfied relation above, i.e., is zero in the time-space dispersive of working face.It is simultaneously guarantee LgcNot with wavelength
Change and change, then there must be d1=d2, and γ=γ ', the i.e. grating constant when 1 constant of the first grating and the second balzed grating, 4
It is identical, when the incidence angle 401 of first time diffraction and the equal incidence angle 402 of third time diffraction, Lgc=Lgg'.It is i.e. each in light beam
The all wavelengths ingredient of light on working face 5 only by the same point, without the time difference between different wave length, in this way, from
Fundamentally eliminate influence of the Grating angular spectral dispersion effect to inclination of wave front technical application effect.
