Aberrations in shift-invariant linear optical imaging systems using partially coherent fields

Mario A. Beltran, Marcus J. Kitchen, T. Petersen +1

Here the role and influence of aberrations in optical imaging systems employing partially coherent complex scalar fields is studied. Imaging systems require aberrations to yield co…

Bloch Sphere Catastrophes

Samuel A. Eastwood, David M. Paganin, Timothy C. Petersen +1

Caustics are optical phenomena which occur when a family of rays creates an envelope of divergent intensity. Here we show that caustic surfaces also appear when a real or complex f…
