Claim 15:
16. A method according to claim 15, further comprising:
projecting polychromatic light with the first pattern into one of a first pair of in-coupling diffractive optical elements with a first repeated diffraction spacing corresponding to the first wavelength and into one of a second pair of in-coupling diffractive optical elements with a second repeated diffraction spacing corresponding to the second wavelength;
projecting polychromatic light with the second pattern into the other of the first pair of in-coupling diffractive optical elements with the first repeated diffraction spacing and into the other of the second pair of in-coupling diffractive optical elements with the second repeated diffraction spacing;
transmitting the first pattern of light from said one of the first pair of in-coupling diffractive optical elements to the first region of the first out-coupling diffractive optical element and from said one of the second pair of in-coupling diffractive optical elements to the second region of the second out-coupling diffractive optical element; and
transmitting the second pattern of light from said other of the first pair of in-coupling diffractive optical elements to the first region of the second out-coupling diffractive optical element and from said other of the second pair of in-coupling diffractive optical elements to the second region of the first out-coupling diffractive optical element.
