运用微扰理论证明了热波成像在一定条件下具有线性平移不变性。
Abstract In the approximation of pertubation,the thermal wave imaging was proved to be linear shift invariant under some conditions.Based on this fact ,the signal formation mechanism of such a system was interpreted when used in nondestructive evaluation of opaque materials.
