Abstract
Abstract A thermal imaging device includes an array of pyroelectric infra-red detector pixels. An array of pillars carries electrical signals between each detector pixel and a respective signal processing circuit formed on a semiconducting substrate. Each circuit is connected to an individual display device carried by the substrate.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
62 words
A thermal imaging device comprising an array of pyroelectric detector elements, means effective to transfer electrical signals between each detector element and a respective circuit means formed on a semiconducting substrate, and an array of display pixels, each display pixel being carried on a major surface of said substrate and connected to the output of a respective one of said circuit means.
Claim 2
Dependent Claim
62 words
A thermal imaging device comprising an array of pyroelectric detector elements, means effective to transfer electrical signals between each detector element and a respective circuit means formed on a semiconducting substrate, and an array of display pixels, each display pixel being carried on a major surface of said substrate and connected to the output of a respective one of said circuit means.
Claim 3
Dependent Claim
15 words
A device according to claim 1 in which the display pixels comprise light emitting diodes.
Claim 4
Dependent Claim
15 words
A device according to claim 1 in which the display pixels comprise liquid crystal devices.
Claim 5
Dependent Claim
28 words
A device according to claim 1 in which the means for transferring electrical signals comprises an array of pillars which also supports the array of pyroelectric detector elements.
Claim 6
Dependent Claim
23 words
A device according to claim 4 in which each pillar is connected to a pyroelectric detector element by an elongate electrically conductive strip.
Claim 7
Dependent Claim
38 words
A device according to claim 1 in which the array of pyroelectric detector elements is disposed adjacent a first major surface of the substrate, and the display pixels are carried on the opposing major surface of the substrate.
Claim 8
Dependent Claim
27 words
A device according to claim 1 in which the array of pyroelectric detector elements are disposed adjacent the major surface of the substrate carrying the display pixels.
Claim 9
Dependent Claim
42 words
A device according to claim 7 in which the substrate includes at least regions which are infra-red transparent, incident infra-red radiation is arranged to be directed onto the opposing major surface of the substrate to the major surface carrying the display pixels.
Claim 10
Dependent Claim
56 words
A device according to claim 7 which a dichroic mirror is disposed between the source of incident infra-red radiation and the array of pyroelectric detector elements, the mirror being effective to direct incident infra-red radiation onto the array of pyroelectric detector elements, and to direct visible light from the array of display pixels towards a detector.
