Generalized grating imaging using an extended monochromatic light source
It is a well-known fact that one grating can act as an imaging element for another grating when the first is illuminated with an extended monochromatic light source.

| Zusammenfassung: | It is a well-known fact that one grating can act as an imaging element for another grating when the first is illuminated with an extended monochromatic light source. The conditions for image formation in such a system are studied when the finite size and position of the broad light source are considered. From the presented analysis, expressions for the location and the depth of focus of such images can be derived. |
