摘　　要：介绍一种体积小、重量轻、图像清晰、功能多样的空间频谱演示仪。仪器中采用激光和白光双光源，使用对称移动的低通滤波器和ＣＣＤ探测器，既可演示激光空间频谱又可演示白光假彩色图像编码。The space frequency spectrum demonstration instrument on small volume、 light weigh、 distinct picture and diversified function was introduced in the paper. He Ne laser and white light were both adopted in the instrument, the low pass wave filter of symmetry shift and CCD detector were also applied, laser space frequency spectrum was not only demonstrated, white light pseudocolor image encoding was but also demonstrated in the apparatus.

关 键 词：空间频谱演示仪 傅立叶变换 图像假彩色编码
