The DeltaTherm system is based on thermoelasticity. Simply stated...when a solid body is stressed it gets slightly hotter or slightly colder. Hotter when it's in compression and colder when it's in tension. That's Thermoelasticity! With DeltaTherm, very sensitive infrared cameras are mated with special high-speed digital electronics to measure the slight temperature perturbations. The result is a full-field stress map in just seconds!
