摘要 |
An imaging method comprises directing electromagnetic waves at a resistive surface 2 so as to induce currents within the surface and cause heating thereof. The resulting thermal image is observed by means of a thermal imager 3. Objects passing across the plane of these waves cause distortions in the thermal image from which the presence of an object 8 within an item of luggage 7 may be detected. A further embodiment (fig 3) invokes direct excitation of an object e.g. the ground (9) to detect the presence of objects (8) beneath its surface. <IMAGE> |
