Embodiment Construction
[0034] The principles and features of the present invention will be described below with reference to the accompanying drawings. The embodiments are only used to explain the present invention, but not to limit the scope of the present invention.
[0035] For the diffraction calculation of the light field transmitted along a straight line, the method of fast Fourier transform plus propagators can be directly used. For the diffraction transmission including the beam reflection process, the existing methods are difficult to directly apply.
[0036] like Figure 8 As shown, an exemplary schematic diagram of ray propagation for a single reflection is provided, and the calculation area grid is still constructed perpendicular to the initial ray according to the existing method. For the main ray, he is in the real space and can perform operations such as tracing rays, reflections, etc., but for the rays that are in the virtual space at the beginning, further processing is required.
