Embodiment Construction
[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0039] In this embodiment, the technical solution of the present invention provides a calculation method for the light-transmitting shielding of components containing metal mesh in a spacecraft. The method uses the smallest repeating unit to model the metal mesh in three dimensions, and obtains The light transmittance of the metal mesh and save the data as a table; use the triangular face to carry out three-dimensional modeling of the metal mesh member, first calculate the positional relationship between the triangular face and the incident light, and look up the table to get the transmittance of the triangular face Light rate, the light intensity of its projection area is reduced accordingly, and the area of the light-transmitting occlusion pattern caused by the metal mesh member is calculated.
[0040] In the present invention, the metal me...
