Comments on "The quasi-linear intensity interferometer"

It is pointed out that the sense in which "linearity" obtains in the proposed "quasi-line" intensity interferometer" is not that its response is linear with respect to the observed source flux; in fact, it is quadratic in this sense, as is the conventional intensity interferometer. Also, a reinterpretation of the operation of the quasi-linear intensity interferometer is given, and a mode of operation equivalent to a current very-long-baseline technique is suggested.
