The one-dimensional thermal quadrupole method is used to evaluate a pulsed thermography measurement at delaminations in a glass-fiber reinforced plastic plate quantitatively. The large-scale delaminations have been induced by tension overload and are air-filled and are usually located at the same depth as the notch bottom of a notch on the rear side. While classical evaluation methods like pulsed phase thermography and thermal signal reconstruction are focused on the delamination depth only, the thermal quadrupole method determines spatially resolved two parameters for delaminations, delamination depth and local thermal resistance. Interestingly, lateral heat flows do not disturb this kind of depth evaluation.

一维热四极杆方法用于定量评估玻璃纤维增​​强塑料板中分层时的脉冲热成像测量。大规模分层是由张力过载引起的，并且充满空气，并且通常位于与后侧凹口底部相同的深度。虽然经典的评估方法（例如脉冲相位热成像和热信号重建）仅关注分层深度，但热四极杆方法确定了分层的空间分辨两个参数，即分层深度和局部热阻。有趣的是，横向热流不会干扰这种深度评估。
