The measure of warship wake bubble is a base for developing an underwater sound and light wake detector. The distribution characteristics of the warship wake were studied, and the difficulties in the bubble image measured by the image method were analyzed. A new method of bubble measure is put forward by use of high speed photography based line lighting lamp-house. The system of bubble controlling is established through the air pump and chinaware. The bubble image of different size is gained, and characteristic of bubble is analyzed based numeric image disposal. The result shows the measure of bubble characteristic by use of high speed photography based line lighting lamp-house is a good way.
