Special optical devices such as diffraction gratings and metamaterial surfaces can bear some of the computational burden in computational sensing and imaging, thereby reducing digital processing or pixel count and thus reducing overall electrical power dissipation.

We present a new concept for the design of optical elements. By specifying a general material with tailored anisotropic refractive index, we design refractive lenses that focus light with diffraction-limited resolution and reduced aberrations.

We report on diffraction-free space-time pulsed light sheets with a control over the beam profile at the pulse center. We demonstrate diffraction-free propagation up to 25 mm of a light sheet with a central peak having a FWHM of 7 µm.

Talbot effect was shown to produce ‘self-healed’ periodic images from aperiodic objects. We experimentally demonstrate that the quality of such images can be enhanced through the recently demonstrated process of passive Talbot amplification.

We demonstrate a generalization of the concept of self-imaging, that allows to create diffraction-induced self-images of a periodic two-dimensional waveform with arbitrary and independent control of the image periods along the x and y dimensions.

Polarization interferometry was employed to make two kinds of Fourier imaging spectrometers; in one case, by temporal scanning of optical path delay through a liquid-crystal cell, and in the other, with relative motion between scene and detector to spatially scan the optical path delay through a position-dependent wave plate.
