Convergent
A special case of optical proximity sensing is ''Focused
Spot'' (aka. ''convergent'' or ''v''-axis) sensing. Here a small spot
of (usually visible) light is focused to a point an inch or so away.
This is useful for accurate edge detection and the detection of
small parts, marks or defects. If is effective at suppressing
interference from background light.
