| 摘 要： | 傅里叶望远术是一种主动式的高分辨率成像技术,它使用激光发射阵列产生的干涉条纹场去照射目标,然后用探测器接收回波信号,再对回波信号作相应处理重构出目标图像.在实验室验证实验中,抽取目标频谱的干涉条纹不是由发射阵列产生的,而是通过改变光束位置的方式获得.对直线干涉条纹抽取目标频谱的原理进行了论述,并提出了一种新的光束移动方...

| Abstract: | Fourier telescopy(FT),an active high-resolution imaging technique,uses linear interference fringes with different spatial frequencies sweeping across a target.The resulting reflected temporal signal is collected by a large receiver of lower optical quality.Different spatial frequencies of interference fringes,which are essential to extract the target spectrum,are produced by changing position of beams many times in the laboratory.The theory about spectrum extraction is discussed,and a novel beam moving mode... |
