High Speed Infrared Cameras Enable Demanding Thermal
Imaging Applications
Recent developments in cooled mercury cadmium
telluride (MCT or HgCdTe) infrared detector technology
have made possible the development of high performance
infrared cameras for use in a wide variety of demanding
thermal imaging applications. These infrared cameras
are now available with spectral sensitivity in a wide
range of bands. Camera features now include high frame
rate imaging, adjustable exposure time and event triggering
enabling the capture of temporal thermal events. These
performance capabilities and camera features enable a
wide range of thermal imaging applications that were
previously not possible.

Advanced Techniques for Measuring Temperature
or Radiance of Thermally Dynamic Events
Many applications require the collection
of radiometric data of targets with large temperature
differences within the scene or of experiments during
which dynamic temperature changes occur over a short
period of time. This paper introduces new proprietary
techniques that enable the collection of radiometric
data under dynamic conditions.

High-performance MCT Sensors for Demanding
Applications
Recent MCT Technology Enhancements Yield
Improved Long-wave Infrared Imaging Performance for R&D
Applications. There are a growing number of infrared
photovoltaic 2D focal plane array (FPA) detectors commercially
available for integration into high performance infrared
cameras. Proper selection of sensor technology depends
on the application and systems requirements.

High-speed IR Camera Captures Images
without Blur: Results Show Benefits of LWIR Spectral
Band
Infrared (IR) cameras can image fast-moving
objects and measure the temperature of any point on an
object without the errors associated with motion blur.
One application is in the study of the thermal characteristics
of tires in motion. Using a high-speed IR camera to observe
tires running on a dynamometer at speeds in excess of
150 mph, researchers can capture detailed temperature
data during dynamic testing to simulate turning and braking
loads.

Measuring Cold Object Temperatures
Using Infrared Cameras
For cold targets a LWIR or VLWIR camera
is superior to MWIR. Data and calculations in support
of this position are given in this paper.

Understanding Infrared Camera Thermal
Image Quality
This paper’s objective is to help
you simplify your understanding of how image quality
is determined. Covered are three topics that directly
influence thermal image quality: pixel resolution, thermal
sensitivity, and non-uniformity correction. A number
of related topics are discussed as well.
