Paper Abstract

Three different techniques for extending the depth of field of a low-power (4x) microscope objective system are examined experimentally: wavefront coding with a cubic phase mask, amplitude modulation with a large central obscuration, and added spherical aberration. Their relative merits are discussed and demonstrated with sample images.
