Abstract: ABSTRACT SYSTEMS AND METHODS FOR PREDICTING VOLUME SOLIDS MEASUREMENT OF PAINTS BASED ON NON-INVASIVE PHOTOACOUSTIC SENSING Volume solids (VS) is considered to be a very important and critical property of paint in paint related industries. Conventional methods for VS measurement are usually cumbersome, time-consuming and laborious. The present disclosure re-solves the problems of the conventional approaches by providing a system and method for predicting volume solids measurement of paints based on non-invasive photoacoustic sensing. The present disclosure provides a non-invasive and compact photoacoustic (PA) sensing method with artificial intelligence (AI) model to predict volume solid measurements of paint samples. In the method of the present disclosure, a time domain photoacoustic (PA) signal obtained from the paint is used to predict the volume solids measurements. A temporal shift of the time domain PA signal is used as a feature and a regression based prediction model is trained to predict volume solids measurements of the paint samples. [
