tof_multipath_phase — OPTICS light_transport op

使い方

Continuous-wave time-of-flight depth when several light paths reach one pixel: the phase of the phasor sum, and its bias against the direct path.

Path k with amplitude a_k and round-trip length L_k (metres) contributes a_k e^{i 2π f L_k / c}; the sensor reports the phase of the sum and converts it to depth c φ / (4π f) (modulo the ambiguity range c / (2f)). Path 0 is the direct one (true depth L_0 / 2). With two paths the bias is atan2(r sin Δ, 1 + r cos Δ) · c/(4π f) (r = a_1/a_0, Δ = the extra phase), positive while 0 < Δ < π.

amplitudes and path_lengths are (K, ...) (paths first) and broadcast against each other.

Returns a dict (a table): phase ([0, 2π)), depth, true_depth, bias (depth units, from the wrapped phase difference), amplitude and ambiguity_range.

Raises ValueError: non-finite values, fewer than one path, a negative amplitude or a zero direct amplitude, a non-positive path length, shapes that do not broadcast, modulation_hz outside (0, 1e10].
