Paper Abstract

The optical sectioning property of confocal imaging systems is perhaps a more important feature than the enhanced lateral resolution which these systems possess. This property permits the in-focus imaging of sections of a thick object. The introduction of axial scanning leads to the ability to produce high resolution images with arbitrary, tunable, depth of field. It is also possible to operate the system as a non contacting surface profilometer. The optical arrangement is shown in the figure and the principle of the depth discrimination is shown by the dashed lines.
