A test unit for quantitative analysis of a contact pattern and a method for quantitative analysis are provided. The test unit comprises an optoelectronic sensor for capturing images of contact pattern paint on a tooth surface of a gear. Furthermore, the test unit comprises a control unit, which is configured for determining and storing a first distribution of an optical parameter of the contact pattern paint across the tooth surface, from the first image. This is captured prior to testing of the gear. After the tooth surface was exposed to a test load, a second image is captured and a second distribution of the optical parameter is determined. The control unit is configured to perform a quantitative analysis of a contact pattern on the tooth surface by determining a deviation between the first and the second distribution of the optical parameter. |
