Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung (01, 17) zur Untersuchung eines Gegenstandes, insbesondere hinsichtlich dessen Oberflächengestalt, - mit einem transportablen Gehäuse (02), das über dem zu untersuchenden Oberflächensegment des Gegenstandes insbesondere von Hand positioniert werden kann, - mit zumindest drei Lichtquellen (06), die mit ihren optischen Strahlachsen (07) im schrägen Einfallswinkel relativ zum zu untersuchenden Oberflächensegment ausgerichtet sind, - wobei die Lichtquellen (07) innerhalb des Gehäuses angeordnet sind und das zu untersuchende Oberflächensegment durch eine Beleuchtungsöffnung (08) im Gehäuse (02) beleuchten können, - mit zumindest einem Lichtsensor (09) zur Erfassung des am zu untersuchenden Oberflächensegment reflektierten Lichts, - mit einer Steuer- und Auswerteeinheit, die mit den Lichtquellen (06) und dem Lichtsensor (09) verbunden ist. Die Lichtquellen (06) sind dabei derart angeordnet, dass ihre optischen Strahlachsen (07) in jeweils unterschiedlichen, nicht parallelen Bezugsebenen verlaufen.
