Flynn discontinuity algorithm code
WebMar 1, 2005 · The phase is unwrapped by Flynn's discontinuity algorithm to produce an image of the variation of the optical distance of the illuminating wave. Objects with indices of refraction that are higher and lower than the mounting liquid are detected as regions in which the phase is increased and decreased, respectively. WebMay 8, 2024 · The angle and discontinuity is determined by gamma. Since the unwrap function applies to column wise, and for cases with angles (other than 0) the discontinuity appears in gamma degrees (so for 30, it would …
