Abstract:
The invention relates to an apparatus comprising: a measuring head (10) having a slot (18) for receiving a measurement cell (26) and means (28) for emitting electromagnetic radiation, and means (32, 36) for detecting radiation from said emission means (28) after it has passed through the measurement cell (26); means (16) for translatably driving and means (12, 14) for translatably guiding, allowing the substantially vertical longitudinal movement of the measurement head (10); at least two recesses (44) each intended for receiving a measurement cell (26) and arranged one above the other in a longitudinal direction, the recesses (44) as well as the driving means (16) and the guiding means (12, 14) being configured such that during the translational movement of the measurement head (10) along the nominal travel thereof each recess is placed inside the slot (18) of the measurement head (10).
Abstract:
This invention relates to a method and an apparatus for characterizing eggshells of eggs, the eggs being supported, comprising: —deforming the eggshell, —scanning the eggshell with a laser beam of a Self Mixing Laser Vibrometer (SMLV) with scanning signals, whereby a reflection light signal of reflection light is obtained, —processing scanning signal and the reflection signal with the SMLV, whereby a mixed signal with crack information is obtained, —during scanning moving the eggs relative to the SMLV, —comparing the signals with preset criteria and characteristics of such eggs, whereby comparative data are obtained, and —characterizing the eggshells on the basis of the comparative data.
Abstract:
Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zur optischen Charakterisierung einer Probe und/oder des/der Materials/ien derselben mit einer zur Beleuchtung eines Probenraumabschnitts, in den die Probe einbringbar ist, mit einfallendem Licht ausgerichteten oder ausrichtbaren Beleuchtungseinheit, einer zum Abbilden der in den Probenraumabschnitt eingebrachten Probe durch Empfang von durch die Probe zurückgeworfenem Licht ausgerichtete oder ausrichtbare Detektionseinheit, die zum Erfassen mindestens zweier unterschiedlicher, bevorzugt zweier orthogonaler, Polarisationsanteile im zurückgeworfenen Licht ausgebildet ist, und einer Auswerteeinheit, mit der in den von der Detektionseinheit aufgenommenen Abbildungsdaten diejenigen abgebildeten Oberflächenelemente (Reflexionselemente) der Probe identifizierbar sind, deren zurückgeworfenes, empfangenes Licht auf einer Reflexion des einfallenden Lichts an der Probe beruht, und mit der die erfassten unterschiedlichen Polarisationsanteile für diese Reflexionselemente zu der optischen Charakterisierung auswertbar sind.
Abstract:
A curved substrate bubble detection method includes: providing, by a first light source and a second light source, parallel light incident to a to-be-tested substrate in different incident directions; obtaining, by a linear array camera, a first image including image information of a first side edge of the to-be-tested substrate; determining location information of a defect region of the to-be-tested substrate according to the first image, and generating a second image including image information of the defect region; binarizing the second image, and determining that the to-be-tested substrate has a bubble defect if there are at least two bright spots in an obtained binarized image, and a distance between any two first bright spots of at least two first bright spots is less than a first preset value. A curved substrate bubble detection system is also disclosed.
