An imaging light guide, comprising: a waveguide formed as a substrate including a first surface having a first surface coating and a second surface, disposed opposite the first surface, having a second surface coating; a first in-coupling diffractive optic (110 BG) formed along the first surface coating and oriented to direct a first beam of diffracted light of a first wavelength range into the waveguide along a first direction; a second in-coupling diffractive optic (110 R) formed along the second surface coating and oriented to direct a second beam of diffracted light of a second wavelength range into the waveguide along a second different direction; a first dichroic patch (210 BG) located between the first surface of the substrate and the first surface coating and formed to: (i) transmit light of the first wavelength range, (ii) transmit light of the second wavelength range through a limited range of incidence angles, and (iii) reflect light of the second wavelength range through a higher range of incidence angles; a second dichroic patch (210 R) located between the second surface of the substrate and the second surface coating and formed to transmit light of the second wavelength range and reflect light of the first wavelength range; a first out-coupling diffractive optic (120 BG) arranged along the waveguide and operable to couple the first beam of diffracted light out of the waveguide, and a second out-coupling diffractive optic (120 R) arranged along the waveguide and operable to couple the second beam of diffracted light out of the waveguide; a first turning diffractive optic arranged along a path in the first direction and disposed to redirect the first beam of diffracted light toward the first out-coupling diffractive optic (120 BG); a second turning diffractive optic arranged along a path in the second direction and disposed to redirect the second beam of diffracted light toward the second out-coupling diffractive optic (120 R). a waveguide formed as a substrate including a first surface having a first surface coating and a second surface, disposed opposite the first surface, having a second surface coating; a first in-coupling diffractive optic (110 BG) formed along the first surface coating and oriented to direct a first beam of diffracted light of a first wavelength range into the waveguide along a first direction; a second in-coupling diffractive optic (110 R) formed along the second surface coating and oriented to direct a second beam of diffracted light of a second wavelength range into the waveguide along a second different direction; a first dichroic patch (210 BG) located between the first surface of the substrate and the first surface coating and formed to: (i) transmit light of the first wavelength range, (ii) transmit light of the second wavelength range through a limited range of incidence angles, and (iii) reflect light of the second wavelength range through a higher range of incidence angles; (i) transmit light of the first wavelength range, (ii) transmit light of the second wavelength range through a limited range of incidence angles, and (iii) reflect light of the second wavelength range through a higher range of incidence angles; a second dichroic patch (210 R) located between the second surface of the substrate and the second surface coating and formed to transmit light of the second wavelength range and reflect light of the first wavelength range; a first out-coupling diffractive optic (120 BG) arranged along the waveguide and operable to couple the first beam of diffracted light out of the waveguide, and a second out-coupling diffractive optic (120 R) arranged along the waveguide and operable to couple the second beam of diffracted light out of the waveguide; a first turning diffractive optic arranged along a path in the first direction and disposed to redirect the first beam of diffracted light toward the first out-coupling diffractive optic (120 BG); a second turning diffractive optic arranged along a path in the second direction and disposed to redirect the second beam of diffracted light toward the second out-coupling diffractive optic (120 R).
