Abstract
Abstract Method and active media for controlled production of physical and refractive index inhomogenetics in a volume of a suspension medium by use of at least two intersecting beams of electromagnetic radiation matched to the excited state properties of molecules in the media. In addition, complex three-dimensional physical and chemical structures are produced by selective excitation of different types of molecules in the media and by employing transportive capabilities of liquid or gaseous support medium.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
76 words
A medium for forming a substantially persistent three-dimensional figure comprising: a substantially transparent dispersion medium capable of maintaining a relatively stable shape containable within a volume; and a first reactant substantially dispersed in said dispersion medium, said first reactant being responsive to energy level changes within said volume at selected locations therein, so as to produce a catalytic agent; and a reactive second component capable of producing said figure by the influence of said catalytic agent.
Claim 2
Independent Claim
76 words
A medium for forming a substantially persistent three-dimensional figure comprising: a substantially transparent dispersion medium capable of maintaining a relatively stable shape containable within a volume; and a first reactant substantially dispersed in said dispersion medium, said first reactant being responsive to energy level changes within said volume at selected locations therein, so as to produce a catalytic agent; and a reactive second component capable of producing said figure by the influence of said catalytic agent.
Claim 3
Dependent Claim
15 words
A medium as in claim 1, wherein said first reactant is an inactivated polymerization catalyst.
Claim 4
Dependent Claim
15 words
A medium as in claim 1, wherein said first reactant is a polymerization catalyst precursor.
Claim 5
Dependent Claim
23 words
A medium as in claim 1, wherein said first reactant is a system composed or crystal violet leuconitrile and a mild reducing agent.
