Abstract: A method of designing an element for the manipulation of waves, comprises: accessing a computer readable medium storing a machine learning procedure, having a plurality of learnable weight parameters. A first plurality of the weight parameters corresponds to the element, and a second plurality of the weight parameters correspond to an image processing. The method comprises accessing a computer readable medium storing training imaging data, and training the machine learning procedure on the training imaging data, so as to obtain values for at least the first plurality of the weight parameters.

Abstract: A method of processing an image is disclosed. The method comprises decomposing the image into a plurality of channels, each being characterized by a different depth-of-field, and accessing a computer readable medium storing an in-focus dictionary defined over a plurality of dictionary atoms, and an out-of-focus dictionary defined over a plurality of sets of dictionary atoms, each set corresponding to a different out-of-focus condition. The method also comprises computing one or more sparse representations of the decomposed image over the dictionaries.

Abstract: An optical element is disclosed. The optical element comprises: a first phase shift mask formed on a first optical material and constituted to generate a positive phase shift, and a second phase shift mask formed on a second optical material and constituted to generate a negative phase shift, wherein the phase shift masks are arranged serially on an optical axis, and wherein a refractive index of at least one of the first and second optical materials varies with the temperature at a rate of at least 50×10−6 per degree Kelvin.
