摘要：
High longitudinal selectivity of the shifting multiplexing with spherical reference wave is proposed and demonstrated. A simplified method based on wave optics is used for calculating the selectivity, and the result fits well the experimental measurement. Under the paraxial condition, a simple formula for the longitudinal selectivity is introduced. With use of an object lens with effective NA = 0.817, we obtain that an FWHM of selectivity is as small as 1 mum. (C) 2002 Elsevier Science Ltd. All rights reserved.
