Thank you for the reply.
Yes. And the sensitivity of the two systems. I'll be producing mean/rms of the pixel shift and drho/dx, drho/dy but how do I then link it to schlieren images for comparison?
hi
I have two sets of images, one schlieren and the other BOS. I need some ideas to explain the flow and see which one gives better flow properties. The flow is just a jet out of a heat gun. Any help is much appreciated
