Shearography - radiative transfer

I would appreciate some help on a specific shearographic problem :

I am trying to enhance the efficiency of our shearographic equipment by determining the best posible thermal load to apply to a given structure. i.e. I want to answer a question such as : is hallogene light or UV that is better suited to provoc the good strain in a composite plate ? To do so I need to find out about :
1 - the thermal properties of the material (aluminium, composite, honeycomb etc...) : emessivity, absorptivitye, ... as a function of wavelength and temperature
2 - the radiated incident spectrum: luminance(lambda, T)

Does anyone knows where to obtain such informations or alternatively is there someone who already solvced this problem (litterature ?)

Thanks in advance

Pierre MARTY
