1. A scanning display for producing an image for viewing by an eye, the image including a plurality of image sectors, comprising:

  • a first beam set modulated according to a first of the image sectors;

    a second beam set modulated according to a second of the image sectors, the second sector being different from the first sector;

    a biaxial scanning device receiving the first beam set and second beam set, the scanning device scanning light in parallel from the first beam set and the second beam set along two axes in a manner which reduces system bandwidth, wherein light from the first beam set is directed toward a first region of a display field to produce the first image sector and light from the second beam set is directed toward a second region of the display field to produce the second image sector, wherein the first region and second region are different regions of the display field;

    a lensing system receiving light generated by the first beam set and light generated by the second beam set, the lensing system defining a first optical path from an input toward an output, the lensing system output adapted for transmitting light to and receiving light from the viewer'"'"'s eye, wherein the light transmitted to the viewer'"'"'s eye forms the image;

    an optical detector receiving a portion of light reflected from the viewer'"'"'s eye;

    means for indicating from the detected received portion of light a position of the viewer'"'"'s eye; and

    means for altering the image as a function of the indicated position of the viewer'"'"'s eye.
