Abstract:
1. A focal plane array package assembly, comprising: at least one active infrared detector pixel element; at least one infrared reference pixel element; an optically blocking structure disposed in spaced relationship with said at least one infrared reference pixel element to completely block infrared radiation from reaching said infrared reference pixel element; and a package assembly lid overlying said at least one active infrared detector pixel element and said at least one infrared reference pixel element; said package assembly lid comprising said optically blocking structure; wherein said at least one active infrared detector pixel element has thermal isolation legs; wherein said at least one infrared reference pixel element has thermal isolation legs; and wherein a length of said thermal isolation legs of said at least one infrared reference pixel element is substantially the same as the length of said thermal isolation legs of said at least one active infrared detector pixel element.
