Testing method and testing platform for light spot patterns of solar light condenser

The invention provides a testing method for light spot patterns of a solar light condenser. The testing method comprises the following steps: firstly, generating light rays which are vertically incident on a solar light condensing lens by utilizing simulation point light sources; then acquiring geometric information about the position and the shape of condensed light on a receiver by utilizing an image detecting technique, and reconstructing and recognizing on a computer; then moving the simulation point light sources fixed on a guide rail along the outer diameter of the solar light condensing lens in parallel by utilizing the electric guide rail with a servo stepping motor, reconstructing and storing the position and the shape of the condensed light after each moving, and automatically analyzing the shape and the position of a light spot on the receiver by testing software after the simulation point light sources move for a cycle, thereby obtaining the accurate light receiving patterns. The invention also provides a testing platform for light spot patterns of the solar light condenser. The testing method and the testing platform provided by the invention can directly measure the actual light spot size after light condensation, and moreover, the obtained light spot is high in size accuracy; additionally, the testing process is automatic, so that the testing efficiency is high.
