Abstract:
Errors in the focuser-generated image are studied that are due to the discrepancy between the assumed and actual intensity distributions of the illuminating beam. The distortions here considered are differences in width and shifts of the beam centre with respect to the focuser centre. The study is carried out by simulating a Gaussian beam focuser over a uniform distribution interval. An approach is proposed to improve focuser precision by decomposing the focuser into parts each of which focuses radiation over the entire focal curve.
