Angle errors of different position deviations of the point light source from the centre of the pinhole within an angle measurement range of ±10 mrad with h = 500 mm. (a) Vertical position deviations from −1 to +1 mm of the point light source from the centre of the pinhole. (b) Horizontal position deviations from 0.1 mm to 1 mm of the point light source from the centre of the pinhole. |
