| 中文摘要 | by properly designing a phase pupil mask to modulate or encode the optical images and then digitally restoring them, one can greatly extend the depth of field and improve image quality. the original works done by dowski and cathey introduce the use of a cubic phase pupil mask to extend the depth of field. the theoretical and experimental researches all verified its effectiveness. in this paper, we suggest the use of an exponential phase pupil mask to extend the depth of field. this phase mask has two variable parameters for designing to control the shape of the mask so as to modulate the wave-front more flexible. we employ an optimization procedure based on the fisher information metric to obtain the optimum values of the parameters for the exponential and the cubic masks, respectively. a series of performance comparisons between these two optimized phase masks in extending the depth of field are then done. the results show that the exponential phase mask provide slight advantage to the cubic one in several aspects.
