Are the Dyson rings around pulsars detectable?

In the previous paper
\citep{ring} (henceforth Paper-I) we have extended the idea of Freeman
Dyson and have shown that a supercivilization has to use ring-like
megastructures around pulsars instead of a spherical shell. In this work
we reexamine the same problem in the observational context and we show
that facilities of modern IR telescopes (VLTI and WISE) might
efficiently monitor the nearby zone of the solar system and search for
the IR Dyson-rings up to distances of the order of 0.2kpc, corresponding
to the current highest achievable angular resolution, 0.001mas. In this
case the total number of pulsars in the observationally reachable area
is about 64±21. We show that pulsars from the distance of the order of
∼1kpc are still visible for WISE as point-like sources but in order to
confirm that the object is the neutron star, one has to use the UV
telescopes, which at this moment cannot provide enough sensitivity.
