摘　　要：A technique of fast 360° spinning 3D measurement is realized.A laser diode used as light source produces 0.5 mm wide slit which is projected onto the surface of an object via a groupe of optical lenses.A CCD camera can grab the reflect curve line and its video output is processed by special hardware circuitries.Then the surface height value which the slit directs to will be directly obtained.The spinning table turns one degree each time and totally 360° 3D information acquisition need only 15 s.The result and conclusion are presented.ＦａｓｔＰｒｏｆｉｌｏｍｅｔｒｙｏｆ３６０°Ｓｐｉｎｎｉｎｇ３ＤＭｅａｓｕｒｅｍｅｎｔ①ＳＯＮＧＹｕａｎｈｅ，ＺＨＡＯＨｏｎｇ，ＣＨＥＮＷｅｎｙｉ，ＴＡＮＹｕｓｈａｎ（ＲｅｓｅａｒｃｈＩｎｓｔｉｔｕｔｅｆｏｒＬａｓｅｒ＆ＩｎｆｒａｒｅｄＡｐｐｌｉｃａ...
