Abstract


There are many advantages of free-form optical components , optical imaging system , not only can effectively correct system aberration , enhance image quality , and can also reduce the number and weight of the system unit . Used in the design of high-performance lighting system can effectively improve the utilization of solar energy design provides considerable freedom . Nevertheless , the optical free-form surface can not enter into the mainstream of modern optical systems , one of the problems is the high-precision , rapid detection technology . Optical freeform surface characteristics and describe methods of learning , summed up in the expression of the optical freeform optical design . Optical freeform detection methods and analysis comparison to elect a most advantageous method - the introduction of micro- lens array to produce multiple field interferogram detection of optical freeform optical interferometer . Around this detection method were analyzed and two optical elements : the microlens array and the finite conjugate optical interferometer to play a key role halo -type standard spherical lens group . Analysis of each of these two components , the first to study the characteristics of the traditional standard spherical lens group and works to analyze the characteristics and working principle of limited conjugate halo standard spherical lens group , through its basic aberration analysis determine viable optical structure optimization analysis , the final design of the two groups to meet the requirements of the standard spherical lens group are better than λ/20 PV value . Statistical analysis, and then the basic structure of the microlens array and parameters derived whose numerical aperture which orders of magnitude, and the existing laboratory microlens array analysis , design of the optical system increases the numerical aperture of microlens array experimental platform structures do theoretical work .
