| Summary: | As the automotive industry always puts safety in focus, they want to develop systems that will facilitate the driver and in the future, eliminate the human factor. These systems require detailed tests and these tests use 3D car targets and other kinds of soft test targets. Unfortunately, there is no standard for when these test targets get too deteriorated for use. This means that there is a need to be able to measure the optical properties of these targets. This has resulted in this degree project being done. This report is the result of a project, which is done by two students at Luleå Technical University. It is done on behalf of RISE in Borås. The project is about how a 3D car target deteriorates when it is repeatedly hit. A literature study has been carried out and a portable measuring equipment has been put together and weatherproofed. When this was done, a test campaign was performed at AstaZero where a 3D car target was repeatedly hit and measurements were taken continuously. Measurement data was analyzed and it showed that the reflectance did not significantly deteriorate around the car, and that the RGB response and u'v’ values were not significantly impaired.
