Abstract
The invention pertains to a device for signature adaptation, comprising at least one surface element (100; 300; 500) arranged to assume a determined thermal distribution, wherein said surface element comprises at least one temperature generating element (150; 450a, 450b, 450c) arranged to generate at least one predetermined temperature gradient to a portion of said at least one surface element. Said surface element (100; 300; 500) comprising at least one display surface (50), wherein said display surface (50) is arranged to radiate at least one predetermined spectrum. The invention also pertains to a method for signature adaptation and an object such as a craft provided with the device according to the invention.
Claims21
A device for signature adaptation, comprising:
- at least one surface element arranged to assume a determined thermal distribution,
- wherein said surface element comprises at least one temperature generating element arranged to generate at least one predetermined temperature gradient to a portion of said at least one surface element,
- said at least one surface element comprises at least one display surface,
- said at least one display surface is arranged to radiate at least one predetermined spectrum,
- said at least one display surface is arranged to radiate at least one spectrum in a plurality of directions, and said at least one predetermined spectrum is directionally dependent, and
- the display surface comprises an obstructing layer arranged to obstruct incident light of selected angles of incidence.
Method for signature adaptation comprising the step of:
- providing a determined thermal distribution to a surface element based on generating a predetermined temperature gradient to a portion of a surface element using a temperature generating element;
- and
- radiating at least one predetermined spectrum from at least one display surface arranged on said surface element,
- wherein said at least one display surface is arranged to radiate at least one spectrum in a plurality of directions, and said at least one predetermined spectrum is directionally dependent, and
- the display surface comprises an obstructing layer arranged to obstruct incident light of selected angles of incidence.
