Laser velocimeter developed to measure flow of air in vicinity of one of blades of helicopter rotor. Image-rotating optic transforms laser beams to rotating reference frame. Transformed beams stationary with respect to rotor blade; enabling continuous monitoring of velocity of flow at some point in reference frame attached to blade, provided that blade did not vibrate.
