lockin_phase — OPTICS lockin op

使い方

Phase map phi (radians, (-pi, pi]) of the part of every pixel that follows the reference -> (H, W) image.

The phase is unaffected by a multiplicative change of the whole pixel signal (reflectance, emissivity, a non-uniform heating or illumination level): it reads where the response is late, not how strong it is. A pixel with zero amplitude has no phase and reads 0.
