ABSTRACT
We present an approach to the analysis of scalar wave focusing. A detailed study is made of an optical system where the basic idea is to define the geometry of the semiperiodic zones within the exit pupil, followed by a numerical integration on these zones. This approach clearly illustrates the nature of the phenomena involved and allows exact computations in focal regions. A practical illustration is presented by considering a meniscus lens system. The method may be readily adapted to a wide range of applications in confocal microscopy, or be used in the analysis of an optical instrument’s resolving power. © 2002 American Institute of Physics.
