【Abstract】 The characteristics and structures of a simple Fabry-Perot and multi-half-wave optic filters were compared.The weaknesses in transmission property of a Fabry-Perot optic filter,such as low peak transmittance.wide band pass,narrow cutoff band,etc. , can be considerably overcome wjth a properly designed multi-half-wave optic filter. Besides, there is much room for improvement or optimization of the new filter.The flowchart used in design optimization of the multi-half-wave filter is also discussed.更多还原
