🧵 interferometers - working

how do they make rays coincide in heterodyne interferometers
i have been thinking about this since some time and i cant come to an understanding of how they can make this happen
in my imagination, centering of the rays is vital for proper interference to occur. so it is an important question to ask, how do they do it
btw, sorry for the absence of question marks. shift button isnt working.
