Title: Ti Hemi boombox experiment

Previous deformation experiments in which IR imaging was used pointed to a correlation in between IR signature in areas where heat was expected to be. The surface is not uniform during deformation experiments which cause cracks in the image in areas with increased temperature. To measure temperature under dynamic conditions, simultaneous reflectivity and radiance measurement under events of interest is needed. To measure a temperature measurement, a Reflectance measurement taken by framing camera at the edge of the camera sensitivity (700nm). Allows relative measurement at this wavelength. At reasonable temperatures the spectral radiance should peak near 2u and be 3-4 orders of magnitude higher than at 700 nm.
