Abstract
Novel measurement techniques based on moiré techniques and optical frequency conversion. For example, in the IR realm, the configuration can be any moiré configuration, the detector is an IR detector, and the light source can be at any wavelength. The optical configuration, the detector, and the type of light source depend on the physical properties of object/scene and the parameter(s) to be measured.
