Time of flight sensing is somewhat new coming into the consumer market although the military and aerospace fields have been using it for decades.  The wikipedia article on it is a good introduction for people who are unfamiilair with it.  And a web search on "iphone time of flight" would probably we worthwhile for a lot of people.

But to your question, to put TOF through the lens, with a bumpout on the side of a camera like you described, the conventional solution would be to put a beam splitter in between the sensor and the lens.  Like the beam splitter in a Sony DSLT camera such as a Sony A99.   That beam splitter takes space and that goes against the trend to make lenses and short and light as possible.  That is one of the reasons mirrorless cameras are taking over from DSLRs (and DSLTs.)
