Cool -- I've got an older gen TOF plus a little oled unit and an old (broken) rangefinder box from a press camera (all sitting in a plastic baggie) that I've been meaning to frankenstein together into a focus assist hybrid display for large-format cameras. Time is short, but I'll get round to it.

Curious how it looks for accuracy once you dig in -- probably less important in your application, but I need <5cm on the near end; much less demanding as distances get larger tho.

Sorry for not giving this earlier, but for opaque targets covering a large portion of the target zone, after throwing a Kalmin filter in, I've been typically getting within a half-centimeter pretty much the whole range (2cm - 4m). Reflective or transparent targets can be less good, with polycarbonate being either much noisier or being consistently a couple cm too far.

Big problem's where a zone is only has small objects very near -- sometimes this will 'just' be off by a centimeter or two more (seems most common in the center?), and sometimes it'll be way far by meters. That's been annoying for the display 'logic', since someone waving their hand at the virtual display is kinda a goal.

Dunno if it would be an issue for a more conventional rangefinder use, though the limited max range and wide field-of-view might exclude it regardless.
