Information on applications for infrared and ultraviolet imaging systems tends to be scanty and widely dispersed.
This is because camera manufacturers tend focus on the products themselves, not applications. It is also because most textbooks on IR and UV technology are outdated and tend to emphasize the basics of radiometry and detection by single detectors, not imaging applications. Finally, industrial users of these cameras are often close-mouthed about what they are doing with them. <br/>
This course gives a non-technical overview of commercial infrared and ultraviolet camera systems, the "taxonomy" of infrared and ultraviolet wavebands, and the wide variety of applications for these wavebands. The course relies heavily on interesting imagery captured by the presenter over the last ten years and uses a SPIE monograph written by the author as a supplementary textbook. <br/>
The course will cover a wide range of IR and UV applications, including:
<ul>
<li> CCDs and CMOS detectors </li>
<li> Infrared focal plane arrays </li>
<li> Cooled and uncooled infrared sensors </li>
<li> Infrared Radiometry </li>
<li> Thermography </li>
<li> Industrial inspection </li>
<li> Research and Development applications </li>
<li> Corona detection and shortwave UV imaging </li>
</ul>
This course will enable the user to understand how an infrared camera system can be calibrated to measure radiance, radiant intensity and apparent temperatures of targets and scenes, and how the camera’s digital data is converted into radiometric data. The user will learn how to perform their own external, "by hand" calibrations on a science-grade infrared camera system using area or cavity blackbodies and an Excel spreadsheet provided by the instructor. The influences of lenses, ND and bandpass filters, windows, emissivity, reflections and atmospheric absorption on the system calibration will be covered. The instructor will use software to illustrate these concepts and will show how to measure emissivity using an infrared camera and how to predict system performance outside the calibration range.
From near-infrared security cameras above your front door, to thermal infrared camera accessories that mount to smartphones, infrared imaging technology is everywhere. But there is still confusion and misinformation about what it is and what it can and cannot do. This 2-hour, high-level introduction to the topic, with minimal math or physics knowledge required, is for the growing number of non-specialists who need to understand infrared imaging technology and its many applications. The presentation materials consist of infrared images from the instructor’s extensive library, the stories these images tell us, how they are made and how the technology and the phenomena it captures relates to the more familiar realm of visible-light cameras and human vision.
This course provides attendees with an overview of the diverse range of applications for NIR and SWIR imaging systems and how these systems are calibrated and characterized. The emphasis is on the capabilities of InGaAs and InSb sensors operating in the 0.7 to 3.0 micron NIR and SWIR bands with discussions of optics and tunable filter technology. Discussion will also include extended InGaAs and VisGaAs, a sensor material with both visible and NIR response.
This short course is a presentation of hundreds of images taken with electronic sensors that cover the spectrum from radio to gamma rays, along with discussions of the sensor technology used to make the images and its applications. The course is non-technical in nature, but will be of interest to imaging professionals and laypersons alike.
