Okay, so handwriing analysis has a bit of a hinky reputation (can you really tell I have problems with my mother by the way I cross my T’s?) But a new method promises accurate interpretation of handwriting. “Their method employs holography. This technique makes three-dimensional images from the interference patterns of two laser beams used to scan an object—in this case a sample of handwriting. When the holographic information in an image is transferred to a computer, that image can be interpreted as a series of troughs of varying depths, denoting the pressure of the pen strokes used to make them.”
