1. A holographic optical element, comprising:

  • first holographic means for transmitting without diffraction a first component of incident light and diffracting a second component of the incident light by a selected angle in a selected plane;

    second holographic means for transmitting without diffraction the first component of the incident light transmitted by said first holographic optical element and diffracting the second component of the incident light diffracted by said first holographic optical element by a selected angle in said selected plane; and

    means for maintaining said first and second holographic means in optical contact so that the second component of incident light diffracted by said first holographic means is transmitted into said second holographic means substantially without refraction.
