Abstract
An IR imaging device includes an optical element receiving infrared radiation from a scene, a filter blocking IR radiation outside of a particular range of wavelengths, an array of sensor pixels to capture an image of the scene based on infrared radiation received through the optical element and filter, the array of sensor pixels comprising a first array of sensor pixels to image gas in within a first spectral bandwidth, and a second array of sensor pixel to sense IR radiation in a second spectral bandwidth where gas is not detected, a read-out integrated circuit (ROIC) and logic circuitry to generate a first image sensed by the first array and a second image sensed by the second array, and gas detection logic to detect the presence of gas in the first image.
