Phase objects - continued
Describes how transparent objects may only retard light without diffracting it
Transform - diffraction - transform - image
Spatial information in the rear focal plane.
Zero order has no information
Spatial information is encoded in the diffracted rays.
Spatial deteil vs acceptance angle
Acceptance angle of objective must be wide enough to collect at least first order diffracted rays
Spatial filtering in the transform plane
Using a small aperture slider to remove diffracted orders in the transform plane eliminates detail in the image plane.
Object detail vs. acceptance angle
The finer the spatial detail in an object the wider the diffraction angle - easily seen with a laser pointer and a fine grating.
