Recognizing its importance is only the fist step to advocate invetion or innovation， and some effective measures should be taken for it. For one thing， our authority should continue to enlarge the recruit of graduate. For another， the conditions of

本文基于二维快速傅里叶方法的基本原理提出了一种新的相位解包算法——菱形种子算法¬ 。该算法通过识别一个种子点，然后依次向相邻四点扩展，再把这四个点作为第二批种子点，依次向各自的四点邻域扩展，以菱形轨迹遍历所有的有效信息点，以到达整幅图像的相位解包。- A new algorism of phase unwrapping for measuring the material object is proposed based on the FFT method——algorism of diamon
