The development of mechallical collimator

After a brief introduction of the mechanical collimator's structure and its performance characteristics,the theoretical explanation and experimental result of every development stage from geometry optics to physical optics,till Fourier optics are summarized since the beginning of mechanical collimator.Comparison between different theories is stated centered on collimating performance.Based on the analysis of mechanical collimator's theory,improvement from one dimensional to two dimensional of the formula derived from Fourier optics is made.Problems about the two dimensional Fourier optics model and methods to solve the problems are discussed.Finally,the possibility and ways to calculate the formula are evaluated,and it reaches a conclusion that the two dimensional Fourier optics model can be established.
