Paper Abstract

We develop a theory for brightfield direct-view microscopy using finite-sized, multiple pinhole arrays in the source and detector planes. We show that the array geometry can be decoupled mathematically from the remainder of the optical system. In particular, we present an expression for the response to a point object and to plane reflector. While the theory applies to an arbitrary distribution of pinholes we consider in detail the case of square, hexagonal and interleaving Archimedean spiral arrays. We also consider the implications of the array configuration on both the optical sectioning strength and the light budget.
