  •   Objective  In order to reduce the space needed on a satellite, this paper proposes a design method for a free-form reflector for collimating illumination of integrating spherical light sources. By using this method, a square irradiance distribution with small diameter can be achieved.
      Method  Firstly, the mathematical model of off-axis reflection lighting of free-form surface is established through the point light source model, then the free-form surface is discretized by Chebyshev points, and the free-form surface model that satisfies the point light source illumination is solved. Finally, the light source characteristics of the integrating sphere are analyzed. The method of free-form surface energy distribution completes the transformation from the point light source illumination model to the integrating sphere illumination model
      Result   The analysis shows that when the illumination area is set at 140 mm*140 mm, the irradiance non-uniformity of the target surface is less than 0.02.
      Conclusion  This method can meet the requirements of light weight, short light path and simple structure for spaceborne calibration.
