Clarification of Gate Terminology
LightField uses the term "gate" for historical reasons related to PI-MAX cameras, which
truly have a gate capability. IsoPlane 81 cameras are not gateable, so the "gate" signal is
merely a timing signal available for the convenience of the user. In experiments with no
background signal, if the "gate signal" triggers a laser probe, for example, then results
similar to a gated experiment can be achieved. If, however, there is a background signal,
the IsoPlane 81 camera will integrate it over the whole exposure time.
