Claim Text:
1. An apparatus for the inspection of an object, especially with regard to its surface stature, said apparatus comprising: a. a transportable housing manually moveable over an object, the object comprising a surface segment to be inspected and defining an inspection plane thereof; b. exactly three light sources having operative illuminants, wherein the three light sources are aligned such that an optical beam axis of each said light source is at an angle relative to the surface segment to be inspected; c. wherein the light sources are arranged inside a housing and wherein a light aperture in the housing is operative to allow the surface segment to be illuminated with light from each of said light sources, each of whose optical paths are substantially parallelized; d. at least one light sensor for capturing reflected light from the surface segment; e. control and evaluation units for coupling the three light sources with the at least one light sensor; and f. one or more lenses placed between each said illuminant of each said light source and the surface segment to be inspected, thereby substantially parallelizing light radiated by each said illuminant as it passes through the lenses and is radiated upon the surface segment, g. wherein said optical beam axes are aligned in respective reference planes intersecting at a line of intersection that is substantially coaxial with an optical axis of the light sensor; and h. wherein each said reference plane is at approximately one hundred twenty degrees (120°) with respect to each other.
