To the best of my knowledge, a thermal gradient is a gradient in temperature, is it not? You say the "changing thermal gradient" suits the idea of an IR detection device, natural fit. I am wondering if you are talking about measuring the gradient in temperature or something else.

My idea of a thermal gradient is the difference between the thermal energy levels of two pieces of matter.
Consider a waterfall, different energy potential between a rock at the top & one at the bottom.
A changing thermal gradient is like the "flow of the water" between those points.
