14. A virtual image system comprising:
-
a tracking unit generating positional data responsive to a position of a passive optical unit, said positional data indicating the position of said passive optical unit relative to said tracking unit, said passive optical unit adapted to fit around portions of a user'"'"'s head;
a control unit generating control signals responsive to said positional data; and
an optical projection unit detached from said passive optical unit, and directing a retinal scanning beam into lenses of said passive optical unit responsive to said control signals when said passive optical unit is detached from said optical projection unit. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A passive optical apparatus comprising:
-
a pair of lenses positioned to refract scanning beam into a user'"'"'s retinas; and
three or more target points positioned at fixed points on or adjacent to said pair of lenses to reflect a signal from a tracking unit, said reflected signal containing positional data identifying a position of said pair of lenses. - View Dependent Claims (30, 31, 32, 33)
