摘要： A diffractive optical element (10) for guiding a light having a color spectrum characterized by a plurality of wavelengths longer than a shortest wavelength, λ B , and shorter than a longest wavelength λ R , the light striking the diffractive optical element (10) at an angle greater than a first field-of-view angle, α - FOV , and smaller than a second field-of-view angle, α + FOV . The diffractive optical element comprising a linear grating (12) being formed in a light-transmissive substrate (14). The linear grating (12) is characterized by a pitch, d, selected so as to allow total internal reflection of a light having wavelength λ B and a striking angle of α - FOV . The light-transmissive substrate is characterized by an index of refraction, η S , larger than a minimal index of refraction, η min , which is selected so as to allow total internal reflection of a light having wavelength of λ R and a striking angle of α + FOV.

摘要： An optical device for enlarging an eye box (20), the optical device comprising: (a) a first optical expander (22) being carried by, or formed in, a first light-transmissive substrate (24) engaging a first plane; and (b) a second optical expander (26) being carried by, or formed in, a second light-transmissive substrate (28) engaging a second plane being spaced apart from the first plane. The first and the second optical expanders designed and configured such that light passing through the first optical expander is expanded in a first dimension, enters the second light-transmissive substrate through the second optical expander, and exits from the second light-transmissive substrate, expanded in a second dimension, hence enlarging an eye box of the optical device in both the first and the second dimensions.

摘要： A diffractive optical element for guiding a light having a color spectrum characterized by a plurality of wavelengths longer than a shortest wavelength, lambda B, and shorter than a longest wavelength, lambda R, the light striking the diffractive optical element at an angle greater than a first field-of-view angle, alpha FOV, and smaller than a second field-of-view angle, alpha 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 lambda B and a striking angle of alpha 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 lambda R and a striking angle of alpha FOV.
