The per-pixel version of :func:csi_signal_simulate: every pixel of the
height_um map gets its own coherence envelope centred on its own height, on
a shared scan grid. The scan axis is FIRST — a stack is what a camera
streams while the objective moves, one frame per plane — which is the same
layout as a video (T, H, W) and not the (H, W, T) of a
:func:photoncount.dtof_cube_simulate histogram cube.
That resemblance to video is not cosmetic and it is measured, not assumed:
handing a translating-grating clip to :func:csi_height_map does not
raise, it returns a height map (see the type note in :mod:opsinterferometry
for the numbers). The registry therefore declares a separate zscan type.
height_um: 2-D (H, W) map of true surface heights, in the scan’s own
coordinate. Every height must lie inside the scan range.
reflectivity: optional (H, W) map of per-pixel fringe-amplitude scale
(>= 0). None = uniform 1. A pixel with reflectivity 0 has
no fringes at all and :func:csi_height_map will refuse it
rather than report the first plane.
(the remaining parameters are :func:csi_signal_simulate’s, applied to every
pixel; noise is sampled once for the whole stack from seed.)
Returns a float64 (n_planes, H, W) stack.
Ground truth: with noise=0, csi_height_map(stack, ..., mode="gaussian")
returns height_um with an RMS error of 2.08e-06 um over a tilted plane
spanning 5.0-7.0 um of a 0-12 um scan, and the per-pixel result is bit-for-bit
identical to running :func:csi_peak_position on each column separately
(both pinned in the tests). Widening the same plane to 2.0-10.0 um degrades
that to 7.06e-03 um — envelope truncation at the scan ends, not the
estimator.
Raises ValueError: everything :func:csi_signal_simulate raises, plus
a non-2-D / empty height_um, a reflectivity that is negative or a
different shape, any height outside the scan range, and a stack over
:data:MAX_STACK_ELEMENTS (n_planes*H*W grows fast — 241 planes of
256x256 is 1.9x the cap). The element cap is applied before the float64
promotion of height_um, not after.
