Embodiment
Below in conjunction with accompanying drawing, further illustrate technical scheme of the present invention by specific embodiment.
With reference to figure 1, one aspect of the present invention proposes a kind of light channel structure, comprise LASER Light Source 33, also comprise collimating element 34, diffraction element 35 and the speculum 36 placed successively along optical propagation direction, described collimating element 34 is collimating lens or the optical element with diffraction structure.
LASER Light Source 33 can be the LASER Light Source of conventional semiconductor laser, semiconductor edge-emitting laser (edgeemittinglaser), vertical cavity surface-emitting laser (VCSEL) or other kind.Semiconductor laser is as LASER Light Source, and volume is little, cost is lower, is convenient to be integrated in miniaturized electronics.
The laser of described LASER Light Source 33 outgoing is non-collimated light, after described collimating element 34, the light of outgoing is collimated light, described diffraction element 35 receives the collimated light from the outgoing of described collimating element 34, the multiple diffracted beam of outgoing, and described speculum 36 reflects described diffracted beam.
In image information processing device, need that collimation is carried out to light beam become preferably collimated light, then allow collimated light, through diffraction element 36, diffraction occurs to form loose some light.
In the present invention, when described collimating element (34) is for collimating lens, described collimating lens is planoconvex spotlight, and the light entrance face of described planoconvex spotlight is plane, and light-emitting face is non-spherical surface, and curved surface formula is:
With aspheric summit for initial point, the optical axis of collimating lens is abscissa x, and y represents ordinate, A, B, C, D, E are high-order term coefficient, generally the value of high-order term coefficient is 0, and wherein, c is the vertex curvature of rotational symmetric aspheric, the mirror vertex curvature radius of rotational symmetric aspheric is R, R and c is reciprocal each other, and k is conic constant, preferably, k is-57, R is 86.133mm.The center thickness of collimating lens is preferably 1.356mm, and refractive index is preferably 1.54, and aperture radius is preferably 2.54mm.
There is the optical element of diffraction structure, its substrate can be lens, speculum, flat board or other Traditional optics, namely have the diffraction structure of certain bits Entropy density deviation in the preparation of the surface of lens, speculum, flat board or other Traditional optics, such as etching produces the embossment structure of two or more step depth.
The diffraction structure of diffraction optical element is the transmittance function of trying to achieve diffraction screen according to incident field and required outgoing light field, generates the phase place wavestrip diffraction structure on surface.
In other words, the diffraction structure of diffraction optical element adopts inverse method for designing to obtain, and the light distribution on known input and output face, asks the phase mehtod on input and output face.
The optical wavelength of the emergent light of LASER Light Source is less than the characteristic size of diffraction element 35 in the present invention, design process is the inversion process of diffraction process, be such as collimation laser according to incident light, after diffraction optical element, emergent light is the laser forming setting pattern, the known light field that will obtain at Fu Lang and fraunhofer-diffraction region is f (x, y), then to f (x, y) carry out inverse operation, solve FT
-1{ f (x, y) }, due to FT
-1what { f (x, y) } obtained is continuous distribution function, so the PHASE DISTRIBUTION of reality also needs to be debugged by the thickness of diffraction element, formula is:
In formula, h is diffraction element thickness, and λ is the optical wavelength of incident light, and φ is PHASE DISTRIBUTION, and n is constant; Phase place can not be made to reach continuous distribution when actual fabrication diffraction element, need scalar quantization be adopted, but scalar quantization can bring error into, in actual fabrication process, computational accuracy, less error can be improved by optimized algorithm.
In the present invention, when collimating element 34 is for having the optical element of diffraction structure, it is dull and stereotyped DOE (DiffractiveOpticalElement that collimating element 34 is preferably substrate, DOE), this DOE has the diffraction structure of the embossment of certain bits Entropy density deviation, and cross section is have two or more concavo-convex step embossment structure, the thickness of substrate is roughly 1.0 μm, μm represent micron, the height of each step of thickness of substrate is uneven, is 0.7 μm-0.9 μm.

Collimate non-collimated light with collimating lens, when the Thickness Ratio of collimating lens is thinner, focal length is longer, cause light path to extend, and when the focal length of collimating lens is shorter, Thickness Ratio is thicker, suitably can shorten light path.
Compared with collimating lens, the thickness of DOE is thinner, and when collimating non-collimated light, its placement location is any, not by the impact of focal length, DOE can near the light-emitting window of LASER Light Source, and diffraction element 35 also can near DOE, speculum 36 also near DOE, thus can shorten light path effectively; The thickness of DOE can be very thin in addition, shorten light path further, and DOE can not produce aberration.
Diffraction element 35 of the present invention is for having the optical element of diffraction structure, being preferably substrate is dull and stereotyped DOE (DiffractiveOpticalElement, DOE), this DOE has the diffraction structure of the embossment of certain bits Entropy density deviation, and cross section is have two or more concavo-convex step embossment structure.
The diffraction structure of diffraction element 35 is the phase place wavestrip diffraction structure that the transmittance function that calculates according to the light field of described non-collimated light and the light field of described collimated light is corresponding, namely the concrete diffraction structure of diffraction element 36 is the transmittance functions of being tried to achieve diffraction screen by given incident non-aligned light field and required outgoing collimated light field, generate the phase place wavestrip diffraction structure on surface, thus obtain the diffracting surface structure of diffraction element 36.
