Holographic optical system design

Is the aberration compensation. c. Recording system design can compensate for this aberration holographic lens to eliminate it in the records of the same principles with the use of the eccentric system. Proud of holographic lens in the system when the system must be slit beam expander optical recording, and recording the optical system itself also needs to correct aberration. This can make the holographic lens produced in the record as to the minimum base difference,[link widoczny dla zalogowanych], but to completely eliminate holographic lens aberration is simply impossible. d. Multiple holographic element of compensation. Production of a compensation component with the same interest,[link widoczny dla zalogowanych], it's like the difference with the other components of a holographic aberration in the opposite direction, you can achieve aberration compensation, this combination also need regular contributions to optical components target the poor. A more realistic approach is to group sets of several compensation applications. Comparing Taiwan to get reasonable optical system structure and satisfactory as the quality of results. 4. Calculation of non-coaxial optical system discussed above holographic aberration compensation optical system, using both the eccentricity and tilt meters have a greater optical system aberration, holographic optical system design is necessary methods. Calculation of the main points of this system is the coordinate transformation and solution of the coordinates of points of light projection. Figure 5 Schematic diagram of the eccentric system to calculate the coordinates. O. Y. Z plane for the first l coordinates, OYZ plane coordinate system for the first 1,[link widoczny dla zalogowanych], Z for the system reference axis, the angle between the axis of the two refractive surfaces 0, A, A, respectively, relative to baseline for the two surface vertices of the eccentric shaft. If I find QQ surface refraction of light through the direction of the light must first coordinate transformation. Coordinate translation to tX = Xl, Y = YI a (A a A) (5) Z, = Z, 5-D coordinate rotation circle; set the direction cosines of the axes are L-ML, N: L2, M2, N ? jL?, M, N. Coordinate transformation form a new axis. xYZ, I {XL1fMliNl new coordinate transformation is: X = LX + L2Y + L3Z) Y = MLX + M2Y + M3Z (6) Z: Nix + NzY + N. Zj Figure 5, the transformation is clockwise around the x-axis 180. First, the transformation matrix should be: * 35 * one by one glass (7) (8) rL,[link widoczny dla zalogowanych], fL, lj obtained in a plane of light projected point coordinates x, Y, z direction cosines of the hard light L, M , N we have the conditions for space ray tracing. 5. Holographic optical system to achieve automatic balancing design aberration holographic aberration correction optical system is based on the requirements of bad objects, by modifying the structure parameters, and ultimately meet the design requirements are a set of best parameter set units. Payment information to modify the optical system parameters △ Pi can be a radius, and asked caries, material, record parameters,[link widoczny dla zalogowanych], eccentricity, inclination angle. Choice because of its light is not symmetric system, must be set in the whole sample space as light. Optimal design method with poor balance as the number of garden design system for evaluation of F and Aberration 5y; a smell of the relationship; kF = Σa. (△ y) (110) i1 where weighting factor aj for the poor car design as nonlinear equations by successive approximation method to control the linear equation △ P-bit linear range, adding in the least squares method based on damping factor D, the damped least square method. New evaluation function is: NF = F + DΣ △ P; fl】) j = 1.36 'choice when the initial structure is not reasonable, so that by controlling the damping factor D relentless reduced to approximately linear within in order to avoid the solution of chromium appear meaningless. Specific design, like the difference is the weight coefficient can be given quite a spread, depending on variables like the delicate situation l {VII right to modify an aberration coefficient. In the optimal design parameters of the new system solutions, in addition to control and balance as a large number of poor, will also be given control of all the boundary conditions. This can reduce the computational process too much manual intervention and action to improve the design of the latch and the degree of accuracy, reduce design time. 'Conclusions discussed in the previous system of holographic optical system design methods, regardless of skew or holographic lens design system in the country are rare. 'We base interest rate according to diffraction theory, the derived surface holographic imaging and trace element formula, combined with an optical system skew ray tracing method, the design for the preparation of a general, skew and holographic optical system design, self-balancing program. 3OO with this program designed to benefit the whole surface of large diameter lens HUD, the diffusion angle of axis is 1.2 mrad, mrad off-axis aberration 3 results meet design requirements. After the holographic aberration compensation optical system to optimize the system structure and other issues, but also for more exploration into the study.
