    Abstract: An apparatus and method for validating a leak survey result obtained from an Optical Gas Imaging (OGI) device is proposed. The validation system is coupled to a gas detection infrared thermography camera that captures the infrared image of a scene which may or may not include a gas plume. The validation system performs operations to validate the leak survey result, which includes acquiring a background temperature of each pixel of the infrared image of the scene, acquiring a temperature of the gas plume or ambient air from a temperature sensor that is coupled to the validation system, calculating a temperature difference of said each pixel between the background temperature of said each pixel and the temperature of the gas plume or ambient air, comparing the temperature difference of said each pixel to a predetermined threshold value, and determining whether the leak survey result of the infrared thermography camera is valid based on the temperature difference of said each pixel.

    Abstract: Disclosed is a portable device for measuring temperature with infrared array sensor. This portable device includes: an infrared array sensor module for taking temperature values in a unit of pixel and including a plurality of infrared sensors arranged in an array of pixels; a controller for calculating a resultant temperature value of a subject with reference to the temperature values taken each by the sensors; a display for expressing the resultant temperature value calculated by the controller; and a view finder with an indicator defining a target point to be measured for temperature and having a profile corresponding to the whole or a local shape of the subject. The view finder is formed of a transparent plate on which the subject's shape is reflected. The transparent plate is formed of: a notch representing the indicator; and a lens at least provided in the indicator.
