Advances in Aerial IR Applications
to produce a report. Where aerial infrared thermography differs from aerial. visible photography is in the time of day when the survey occurs and the wavelength of the imagery that. the detector collects. IR thermography of ground objects is almost always performed at night. Thermography reveals sources...
Correct Use of IR Thermometer
in the bibliography. This manual focuses on the practical operations of noncontact temperature measurement devices and IR thermometry, and answers important questions that may arise. If you plan to use a noncontact temperature measurement device and require further advice, send us the completed...
Near IR Spectroscopy in Process Analysis
advantage of process NIR over IR is the ability to use. fiber optics to transmit light between the instrument and the sam-. Near-IR (NIR) is a spectroscopic method based upon the absorp-. ple over considerable distance. This permits the instrument, a. tion of light in the wavelength region between 700...
Looking Through Matter: Quantitative IR Imaging When Observing Through IR Windows
- the most obvious example. being the observation of objects from a certain distance in the atmosphere. Other examples are the use of IR. transparent windows/ports, film or even a specific gas or liquid in between an IR camera and the object under. study (Fig. 1). In this case, the recorded IR object...
Selecting a Flame Detector
Detectors. When a UV optical sensor is integrated with an IR sensor, a dual band detector is created that is. sensitive to the UV and IR radiation emitted by a flame. The combined UV/IR flame detector. offers increased immunity over the UV detector,, operates at moderate speeds of response...
Airborne Detection of Gas Leaks from Transmission Pipelines by Using a Laser System Operating in Visual, Near-IR, and Mid-IR Wavelength Bands
the ground surface; 2) spectrum-. sensitive passive IR systems which view the ground surface through gas plumes, and 3) passive IR. thermographic systems which monitor temperature variations temperature in leak sites. Systems of the first type become less efficient with squared distance, thus...

What kinds of temperature analysis and report. the future, FLIR has put together a list of 7 Things. generation will you need?. to know when selecting...
A Thermal IR Processing Technique for Detecting and Tracking Objects in Motion
in a complex background. Uncalibrated video-rate thermal imagery from a stationary FPA micro-bolometric IR imager is captured on 8- bit digital media. Frames are then differenced with an adaptive temporal background to remove stationary clutter, and thresholded to select pixels at the tail ends...
The Importance of Spatial Resolution in IR Thermography Temperature Measurement - Three Brief Case Studies
Many modern IR cameras have built-in cross-hairs that show the user the size of the spot being measured. One would think this would solve the problem of measurement error due to a target at too great a distance for its size and IR camera resolution. But in our haste as thermographers under pressure...
Infrared On-orbit RCC Inspection with the EVA IR Camera: Development of Flight Hardware from a COTS System
In November 2004, NASA's Space Shuttle Program approved the development of the Extravehicular (EVA) Infrared (IR) Camera to test the application of infrared thermography to on-orbit reinforced carboncarbon (RCC) damage detection. A multi-center team composed of members from NASA's Johnson Space...
