A method for measuring the size of the dispersed spot of star sensor optical lens is presented. A measurement system consisting of a collimator, a rotary table and a CCD cameral was implemented to measure dispersed spot. After a image is acquired, a method of bibubic interpolation pixel subdivision is used to pick up the gray value of the image, and the size of dispersed spot is calculated by Rayleigh criterion.
