Examining wall paintings

From: Niccolo Caldararo <caldararo>

This is in answer to Dr. Konrad Zehnder's inquiry concerning a
complex building analysis problem.  I recommend you contact Dr. John
Asmus at the Institute for Pure and Applied Sciences at the
University of California in San Diego.  I contacted Dr. Asmus to
work on a project several years ago to help determine if a gigantic
painting by Jay DeFeo had been crushed by a shroud of plaster placed
over it.  John applied ultrasound and microwave to the problem.  I
can not think of a better person to consult with when applying sonic
and light-energy sensing systems to complex materials analysis. John
is an expert in laser technology and has considerable (30 years)
experience working with difficult and unique art problems,
especially regarding buildings.
