Abstract:
Methods and systems for designing electromagnetic wave filters and electromagnetic wave filters designed using the methods and systems are disclosed. In one method, functions are selected whose linear combination define the surface of a filter for producing a desired phase-encoded image. Free parameter values are selected for the function and are varied. The values of the free parameters are observed with regard to an optimization function. Final values of the free parameters are selected based on the optimization function having a specific value or range of values.
Abstract:
An optical imaging system having an aperture comprised of a plurality of concentric annuli. The outer radius of each annulus is proportional to the square root of the number of annuli. Each annulus also having an azimuthally linearly increasing phase profile comprising for a given light wavelength. The system also includes a birefringent plate and the aperture and birefringent plate are adapted to jointly encode the full spatial and polarimetric degrees of freedom of a point source.
