Abstract

A nondestructive method for measuring local weight density has been developed which utilizes ahybrid sensorsystem, i. e., a contactor and an optical sensor. The accuracy of this system as defined by the correlationcoefficient between light intensity and the local weight density is demonstrated to be above 90%.
