Abstract

Fremgangsmåte og anordning for berøringsfri avsøkning av et objekt (1). Lys føres ved hjelp av et for-delingsorgan (11, 12, 13) til objektet og inntilllg-gende flater (2, 16). Et detektororgan (9) detekterer lysom reflekteres av objektet og flatene. Flatene har god refleksjonsevne og detekteringsorganet får det reflekterte lys med høy intensitet fra disse.Lys som treffer objektets kantparti spres ved reflek-sjonen, som medfører detektororganet for lys med lav intensitet. Derved blir intensiteten svært høy for flatene, men ved objektets kontur vil det være lavest. P.g.a. dette, kan signaler som er avhengig av den detekterte intensiteten behandles 1 en datamaskinen. Datamaskinen regner ut en avbildning av objektet, som kan anvendes for f.eks. beregning av objektets lengde, bredde, høyde eller volum.Method and device for non-contact scanning of an object (1). Light is supplied by means of a distribution means (11, 12, 13) to the object and adjacent surfaces (2, 16). A detector means (9) detects light reflected by the object and the surfaces. The surfaces have good reflectivity and the detection means receives the reflected light with high intensity from these. Light which hits the edge portion of the object is scattered by the reflection, which causes the detector means for light with low intensity. This makes the intensity very high for the surfaces, but at the contour of the object it will be lowest. Because of. this, signals that depend on the detected intensity can be processed in a computer. The computer calculates an image of the object, which can be used for e.g. calculation of the object's length, width, height or volume.
