Summary of the invention
The object of the invention provides a kind of recording method of low noise small aberration holographic grating, the light wave recording holographic grating that can utilize simple lens to produce, both to have guaranteed to write down the grating aberration little, reduced the influence of parasitic light and ghost image in the register system again, reduced the noise of record grating.
For achieving the above object, the technical solution used in the present invention is: a kind of recording method of low noise small aberration holographic grating comprises the following steps:
(1) make with reference to grating: adopt the method for holographic recording, utilize the parallel light tube of two little aberrations to write down with reference to grating, and will reset with reference to grating, each described parallel light tube is made up of corrective lens (eye protection) and simple lens;

Embodiment
Below in conjunction with drawings and Examples the present invention is further described:
Embodiment one: shown in accompanying drawing 1 to 3, a kind of utilization with reference to grating regulated the method that the aberration holographic recording optical path is arranged, and comprises the following steps:
(1) make with reference to grating: as shown in Figure 1, adopt the method for holographic recording, utilize the parallel light tube of two little aberrations to write down with reference to grating, and will reset with reference to grating, each described parallel light tube is made up of corrective lens (eye protection) and simple lens;
(2) as shown in Figure 2, corrective lens (eye protection) is removed, and the asterism of recording light is placed near the signal-lens focus, make the light field of the mutual school of the recording light wave component aberration that two simple lenses are formed;
(3) in the reproduction light field of reference grating, the light beam of observing by one of them simple lens 1 outgoing 1 passes through with reference to the zero level transmitted light beam 4 of grating and the interference fringe of light beam 2 by forming with reference to the diffracted beam behind the grating diffration 3 of another simple lens 2 outgoing;
Referring to accompanying drawing 2, this interference fringe has been represented the aberration correction information between two lens;
(4) bend as interference fringe or not equidistant, show that the aberration between two lens is not proofreaied and correct fully mutually, regulate one of them signal-lens rotational orientation and/or asterism position this moment, make interference fringe equidistant, straight, thereby realize that aberration is proofreaied and correct mutually between light beam 1 and the light beam 2, finish the adjustment process of aberration;
(5) take off with reference to grating, as shown in Figure 3, place grating substrate to be recorded, and maintenance is consistent with the dimensional orientation of former reference light grid base sheet;
(6) light field of the mutual school aberration that forms of two light beams that utilize two simple lenses to produce is exposed, and finishes the recording process of holographic grating.
The reference grating light path of present embodiment is adjusted principle and is discussed below:
Reproduce principle according to holographic recording, thing light and the reference light COMPLEX AMPLITUDE on record surface can be expressed as:
The superimposed later intensity of reference light and thing light is:
The zero level transmitted light position of reproducing light path thing light distributes mutually:
The negative first-order diffraction light position of reproducing the light path reference light distributes mutually:
The zero order light of thing light and the negative first-order diffraction interference of light PHASE DISTRIBUTION of reference light can be expressed as in the light path of reproducing:
Therefore the relevant light beam of in the reproduction process two can not do requirement to the refractive index homogeneity of grating substrate by same grating substrate.
If the wave aberration of reference grating of record is zero, promptly the phase factor of (4) formula correspondence is zero, and then the phase factor in (7) formula has characterized the wave aberration information of current interference optical field, and it has determined the wave aberration of the grating that will write down.
See Fig. 4 with reference to relation between grating transmission diffraction light wave and the substrate face shape, as seen from the figure,
The optical path difference that is caused by face shape can be expressed as:
OPD＝AC+OB
＝h?cos(α)-h?cos(β)
For the system of symmetry record, α=β, therefore:
OPD＝0
Can think that thus in transmission diffraction one-level light field, grating substrate face shape can not exert an influence to the one-level transmission diffraction, this also is a big advantage of this control method.
From above analysis as can be known, although be not very desirable with reference to grating reflection diffraction face shape, its transmission light field can not be subjected to the influence of the unilateral shape of reference light grid base, and the aberration of transmission light field is only relevant with the aberration of record light field.
In order to verify the feasibility of this method, write down the grating of 200 * 400mm, the empty of grating is 14801p/mm frequently.The first order reflection diffraction aberration of grating is 0.21 λ (detecting wavelength 632.8nm).
