Sunlight on mirrors

Mirrors, mirrors on the wall…the ubiquitous multiple reflection error.

Participants decided when somebody, Janine, could see their face in a horizontal row of adjacent mirrors mounted flat on the same wall. They saw real mirrors and a shop-dummy representing Janine. Such coplanar mirrors reflect different, non-overlapping areas of a scene. However, almost everybody made an unexpected error: they claimed that Janine would see her face reflected in multiple mirrors ...

On time reversal mirrors

The concept of time reversal (TR) of scalar wave is reexamined from basic principles. Five different time reversal mirrors (TRM) are introduced and their relations are analyzed. For the boundary behavior, it is shown that for paraxial wave only the monopole TR scheme satisfies the exact boundary condition while for the spherical wave only the MD-mode TR scheme satisfies the exact boundary condi...

1 Notes on moving mirrors

The Davies-Fulling (DF) model describes the scattering of a massless field by a non-inertial mirror in two dimensions. In this paper, we generalize this model in two different ways. First, we consider partially reflecting mirrors. We show that the Bogoliubov coefficients relating inertial modes can be expressed in terms of the frequency dependent reflection factor which is specified in the rest...

Interactive comment on “Rugged optical mirrors

I think this work is very important for the future operations of TCCON and NDACC stations in remote and harsh environments. This paper has the potential to be referenced numerous times by both TCCON and NDACC networks. However, as reviewer #1 already stated, the authors need to deepen the paper a bit more, specifically on the characterization of the results using the new mirrors. I recommend th...
