<ul><li>Researchers at Tampere University have discovered that complex light structures can cause deformations when reflected off flat surfaces.</li><li>The deformations reveal valuable information about the material properties of the reflecting object.</li><li>This phenomenon, known as 'topological aberration,' confirms a prediction made over a decade ago.</li><li>The discovery could lead to new methods for measuring material properties using structured light waves.</li></ul>
