plot_gram

lenstest.ronchi.plot_gram(D, RoC, lpm, z_offset, conic=0, phi=0, on_grid=False, invert=False)[source]

Plot cross-sections on projection screen at a distance of RoC.

Parameters:

  • D – diameter of mirror [mm]

  • RoC – radius of curvature of mirror [mm]

  • lpm – line pairs per mm [1/mm]

  • conic – conic or Schwartzchild constant [-]

  • phi – CCW rotation of Ronchi ruling from vertical [radians]

  • on_grid – if False generate points on a grid

  • invert – set to True to invert ruling

Returns:

Nothing.
