Paper Abstract

A method for collimation test by utilizing various binary spiral gratings is developed in this paper. Detailed discussion has been focused on the means to improve sensitivity and the optimum tuning mode giving the extremum resolution is proposed. Experimental results indicate that this method is a feasible and promising one.
