Abstract
This invention presents a method of clearing a sensor field of debris, including liquids, through the use of an air curtain. An embodiment of this invention addresses the problem of impurity buildup in the sensing field of an optical sorter. An air curtain is created which prevents film buildup between the light sensor and the light source by blowing material and impurities, which form the film as they fall off articles being sorted, out of the sensing field.
