摘要
The present invention relates to methods for the contactless and non-destructive determination of the layer thicknesses (d) of paint layers of vehicle parts (12), comprising the following steps: - Providing a vehicle part (12) with a first paint layer (26) applied to the vehicle part (12) has a first layer thickness (d1) and at least one further lacquer layer (28, 32, 36) applied to the first lacquer layer (26), which has a further layer thickness (d2, d3, d4), at least the further lacquer layer (28, 32 , 36) or one of the further lacquer layers (28, 32, 36) is optically opaque, - determining the layer thickness (d2, d3, d4) at least the further lacquer layer (28, 32, 36) by means of a device (10) which is used for Performing an optical coherence tomography, the device (10) has at least one radiation source (14) for providing electromagnetic radiation and the electromagnetic radiation has a wavelength provides lengths (λ) of 100 to 15 * 10 sup 3 /sup nm and in particular 380 to 800 nm. The invention also relates to a device (10) for the contactless and non-destructive determination of the layer thicknesses of lacquer layers (26, 28, 32, 36) of vehicle parts (12) which is set up to carry out such a method.
