Abstract
A system for detecting radiation using an array of cells containing a metastable material together with sensing apparatus and display apparatus.
Claims12
A method of changing the state of polarization in a metastable material comprising:
- providing a metastable material in a cell in an array in a first state of polarization;
- polarizing the metastable material to a second state of polarization;
- subjecting the metastable material in the second state to an opposite polarization without causing the metastable material to return to the first state of polarization;
- and
- subjecting the metastable material to a source of radiation causing at least some of the metastable material in the cell to return to the first state of polarization.
