Windshield Glass Reflections - How to Remove Them

by Bernie Lyon, Gary Orlove, and Jason Gagnon
"I do a lot of windshield defrost testing at different temps. And I wonder is there any way that can keep from having the camera and myself reflected back into the images."
Glass is about 15% reflective in the 8-12 micrometer waveband. If you are directly facing the windshield, you will inevitably get a reflection of yourself and the camera. I'm sure you have seen this.
One option is to change the angle at which you are observing the windshield, see the image below. If you are at point A, you and the camera will be reflected. If you are at point B, the camera will reflect whatever is above the vehicle, represented by C.

Cost Avoidance/Energy Savings for IR Thermography

"Has anyone documented Cost Avoidance Or Potential energy savings using Thermography. Ex. Downtime, Labor, Materials. I would be interested in understanding how you determined final cost or energy savings."
This is the $64,000 question, how to justify the cost and benefits of an IR program. The methods used vary depending on your situation, what downtime costs in your facility, overtime and rush ordering to get new parts, lost production cost, your energy cost, etc.
I have selected several white papers that illustrate how different organizations have calculated their costs. Use them as examples of what can be done, and how they are presented.   Right click each image to download the white papers in pdf format.
