Claim Text:
1. A calibration and verification system for a gas imaging camera, comprising: a background board maintaining a uniform temperature; a target cell filled with a target compound at a given concentration in an inert reference gas and disposed in front of the background board; a reference cell filled with an inert reference gas and disposed in front of the background board; and an analyzer coupled to the camera that captures images of the target cell and the reference cell, the analyzer including a machine readable storage medium that provides instructions that cause a machine apparatus to perform operations to verify the camera's performance, the operations comprising: detecting an average intensity of rays passing through the target cell; detecting an average intensity of rays passing through the reference cell; acquiring an intensity difference between the average intensity of rays passing through the target cell and the average intensity of rays passing through the reference cell; and acquiring a temperature difference between a temperature of the background board and a temperature of the target cell.
