Meanings of diffusive regime in inglés

Compared with the conventional amplitude method, the acoustic spectral method provides greater quantification accuracy in the optical diffusive regime.

Photoacoustic (PA) microscopy (PAM) can image optical absorption contrast with ultrasonic spatial resolution in the optical diffusive regime.

In varying the sample thickness, l(s) is determined, the coherent and diffusive regime are distinguished, and the transition from one to the other is followed.
