if you split a laser then let a beam pass
thro a semitransparent 10m chamber felt with
stuff and bul****, but not changing the origianal
color,

then tha other beam you
guide by mirrors thro empty air, then again
you mix them again and point to a
target 10m from source

now, according to basic homodyne physics, there
will be speed differences when subtracting emitter
speed from tha detected speed

now, if small speed differences than there will be
som phase shifts

now even more,
if much larger speed differences, then there will
still be only phase shifts, becus you cant tell
which phase shift is which, becus no matter how
short pulse you send, there will always be a lot
of periods, accordingly you cant tell how many
periods are jumped over

therefore you only can detect at best single period
doppler shift

xxein: A 'patterned pulse' would allow you to break that barrier you
put up for yourself.

how is that patterned pulse looking like

how short is tha pulse

how many periods are in such a pulse
