Abstract: A display has an image generator; a partially transmissive mirror having a curved surface; a beam splitter to reflect incident light toward the curved surface; and an optical image relay that defines a path to relay light to a curved focal surface of a partially transmissive mirror, the curved focal surface is between a curved reflective surface of the partial mirror and the beam splitter. A prism has a folding surface in the optical path for light from the image generator, wherein an aperture stop for the relay lies within the prism. A first plano-aspheric lens, against the prism input surface, guides light from the image generator toward the folding surface; a second plano-aspheric lens, in optical contact against the prism output surface, directs light to the curved focal surface. The relay, curved mirror, and beam splitter form an exit pupil for viewing the scene with a 2D image superimposed.

Abstract: An optical apparatus for imaging a sample has a scanning apparatus having a laser energizable to direct an input beam of a first wavelength to a reflective scanner that is rotatable about an axis and a toroidal mirror surface that is symmetric about said axis and is disposed to direct scanned laser light of the first wavelength toward the sample in an arcuate scan pattern. A compensator in the path of the input beam is formed to correct one or more aberrations of the toroidal mirror surface. Telecentric collector optics define a collection path that conveys, to a detector, scanned light of a second wavelength that is excited from the scanned sample.

Abstract: Systems and methods for heating a battery, which may be performed alone or in combination with charging or discharging a battery. In some implementations, heating involves applying an alternating current waveform, which may be sinusoidal, to a battery. In some implementations, the heating signal is applied at a frequency and/or current with little or no net charge to the battery.
