[0004] However, this device has the disadvantage of needing to supply current to a single light source configured on a removable carrier
Moreover, the damage of such a single light source has to replace the entire carrier

Embodiment Construction

[0094] figure 1 is a schematic diagram of an apparatus 1 for optical property detection of a surface 10 according to the present invention. The device 1 has an optics 12, provides various measuring instruments and encloses a measuring space. In this case, the reference numeral 2 designates a light source, which emits light and emerges along the dotted line S1 through the opening 30 of the measurement volume onto the surface 10 (the linearly polarized light beam falls on the surface 10 ). A plurality of detector arrangements registers this light that is projected back (that is to say in particular scattered and / or reflected) by the surface 10 .

[0095] The reference numeral 4 thus designates a first detector arrangement 4 which registers radiation at an angle of arrival a1 , determined from the radiation direction S1 , and which is reflected and / or scattered by the surface 10 . The reference numeral 6 designates a second detector arrangement 6 which records the light rays sc...

Abstract

The invention relates to an apparatus for the investigation of surface properties with a housing, a light source which directs light through an opening in the housing onto a surface to be investigated, with a first detector device which is arranged inside at a first pre-set angle with respect to the light beam radiated onto the surface by the light source, with a second detector device which is arranged at a second pre-set angle with respect to the light beam radiated onto the surface by the light source and with a third detector device which is arranged inside the housing at a third pre-set angle with respect to the light beam radiated onto the surface by the light source. According to the invention the apparatus has at least two filter elements with optical properties which are different from each other which are arranged on a common carrier movable with respect to the light source, in such a way that each of these filter elements is optionally capable of being brought into a beam path between the light source and the surface.

Description

technical field [0001] The present invention relates to a device and method for detecting surface properties, in particular to detecting optical surface properties such as especially but not limited to color, colourprogression, surface smoothness and the like. Background technique [0002] Such devices have long been known from the prior art. High-quality surfaces, such as in particular body paints, often have a variety of widely different optical properties. Under certain conditions, it is helpful to objectively determine these optical properties, or to measure how they behave under different lighting conditions. For this reason, it is known from the prior art that these surface properties can be determined by means of various devices and methods. In this way, US 2007 / 0206195 describes, for example, a device for determining surface properties which has a plurality of detector elements which are able to detect scattered radiation from the surface to be tested. Various fil...
