ISO-FLUCS: homogeneous laser scanning for an even time-averaged temperature distribution on the sample while still inducing net thermoviscous flows.

Caption

A) Simulated temperature distribution produced by repeatedly scanning an IR laser along a single line. The highly localized heating entails a relatively substantial temperature increase along the track. B) A two-step scan pattern heats the entire ROI uniformly: forward followed by backward scans aim to cancel net flows everywhere except on the ‘flow line’ (middle line), where scans point in the same direction, and their effects are reinforced.
