ABSTRACT:
A method of observing information includes the steps of converting a radiation beam into a visible harmonic beam conforming to the information and observing the information by the harmonic beam. An apparatus for observing information therethrough includes a source for producing a radiation beam conforming to the information, and a converter for converting the radiation beam into a visible harmonic beam, with the information being observed with the aid of the harmonic beam. In addition, a head-up display apparatus includes a source for producing a radiation beam conforming to information to be displayed, a converter for converting the radiation beam into a visible harmonic beam, and a beam combiner for receiving the harmonic beam and directing it in a predetermined direction to effect the display of the information by the harmonic beam.
