中文摘要:

In this paper a millimeter-wave(MMW)squint indirect holographic method is presented,which is suitable for imaging with a large field-of-view.The proposed system employs the squint operation mode to remove the background and twinimage interferences,which achieves a similar effect to off-axis holography but leaves out the large-aperture quasi-optical component.The translational scanning manner enables a large field of view and ensures the image uniformity,which is difficult to realize in off-axis holography.In addition,a corresponding imaging algorithm for the presented scheme is developed to reconstruct the image from the recorded hologram.Some imaging results on typical objects,obtained with electromagnetic simulation,demonstrate good performance of the imaging scheme and validate the effectiveness of the image reconstruction algorithm.

英文摘要:

In this paper a millimeter-wave (MMW) squint indirect holographic method is presented, which is suitable for imaging with a large field-of-view. The proposed system employs the squint operation mode to remove the background and twin- image interferences, which achieves a similar effect to off-axis holography but leaves out the large-aperture quasi-optical component. The translational scanning manner enables a large field of view and ensures the image uniformity, which is difficult to realize in off-axis holography. In addition, a corresponding imaging algorithm for the presented scheme is developed to reconstruct the image from the recorded hologram. Some imaging results on typical objects, obtained with electromagnetic simulation, demonstrate good performance of the imaging scheme and validate the effectiveness of the image reconstruction algorithm.
