Abstract
Method and media are provided for producing three-dimensional sensible objects by the intersection of radiation beams, whereby an active region is produced as a result of the intersection of said beams raising a molecule in the active region to its excited state. Particularly, non-radiation emissive active regions are formed which generate the sensible object.
Claims15
A medium for forming a substantially persistent three-dimensional sensible object comprising:
- a substantially transparent dispersion fluid capable of maintaining a relatively stable shape containable within a volume;
- and
- a photo-reactant substantially dispersed in said dispersion fluid, a molecule of said photo-reactant being responsive to a first photon of optical radiation emitted in a first selected spectral region to excite an electron to an excited state, said molecule being further responsive to a second photon of optical radiation emitted in a second selected spectral region to generate a mono-molecular chemical reaction at a single reaction site for rapidly forming said sensible object without migration of molecular reactants.
A medium for forming a substantially persistent three-dimensional sensible object substantially opaque to optical radiation within a selected spectral region comprising:
- a substantially optically transparent, morphically stable dispersion fluid containable within a volume;
- and
- a photo-reactant substantially dispersed in said dispersion fluid, substantially each molecule of which photoreactant being responsive to the simultaneous confluence of photons of at least two beams of optical radiation of substantially identical wavelength, and wherein said wavelength is matched to the spectral region of maximum optical absorption to generate a mono-molecular reaction characterized by an excited molecular state at a single reaction site such that the energy difference between said excited state and a ground state is greater than the energy of the excitation photon but less than twice the energy of said excitation photon for rapidly forming said sensible object without migration of reactants.
A medium for forming a substantially persistent three-dimensional sensible object substantially opaque to optical radiation within a selected spectral region comprising:
- a substantially transparent morphically stable dispersion fluid containable within the volume;
- and
- a photo-reactant substantially dispersed in said fluid, substantially each molecule of said photo-reactant being responsive to the simultaneous effect of at least two optical beams of different wavelengths and matched to a characteristic spectral absorption region of said photo-reactant such that the wavelength of a first optical beam (hv.sub.1) and the second optical beam (hv.sub.2) and the energy difference (E) between a selected excited state and a ground state satisfy the following criteria:
- E .ltoreq. (hv.sub.1) + (hv.sub.2)
- (hv,) >
- (hv.sub.2) ;
- and
- E >
- 2(hv.sub.2) ;
- in order to generate a mono-molecular reaction at a single reaction site for rapidly forming said sensible object without migration of reactants.
