Abstract: An optical apparatus for transmitting light having a spectrum of wavelengths is disclosed. The apparatus comprises a plurality of optical devices design and constructed to decompose the light into a plurality of portions, respectively corresponding to different sub-spectra of the spectrum, such that each portion of the light is transmitted within a different optical device.

Abstract: A binocular device for transmitting an image into the eyes is provided. The binocular device comprises a first monocular device, for providing one eye with a first asymmetric field-of-view, and a second monocular device for providing another eye with a second asymmetric field-of-view, where the first and second asymmetric field-of-views are mutually complementary to a combined field-of-view, wider than each individual asymmetric field-of-view.

Abstract: A diffractive optical element for guiding a light having a color spectrum characterized by a plurality of wavelengths longer than a shortest wavelength, &lgr;B, and shorter than a longest wavelength, &lgr;R, the light striking the diffractive optical element at an angle greater than a first field-of-view angle, &agr;−FOV, and smaller than a second field-of-view angle, &agr;+FOV. The diffractive optical element comprising a linear grating being formed in a light-transmissive substrate. The linear grating is characterized by a pitch, d, selected so as to allow total internal reflection of a light having wavelength of &lgr;B and a striking angle of &agr;−FOV. The light-transmissive substrate is characterized by an index of refraction, ns, larger than a minimal index of refraction, nMIN, which is selected so as to allow total internal reflection of a light having wavelength of &lgr;R and a striking angle of &agr;+FOV.
