Title
(EN) OPTICAL REFLECTION SENSING ARRANGEMENT FOR SCANNING DEVICES
(FR) AGENCEMENT DE DETECTION DE REFLECTION OPTIQUE POUR DISPOSITIFS D'ANALYSE
Abstract
(EN)
The optical scanner uses a unique compound optical system for processing reflected radiation in a manner to reduce the variations caused by changing position of a scanned substrate in a guideway. Two sources of radiation are directed at similar angles to the surface to be screened and the radiation is distributed over a larger area. Changes in position of the substrate in the guideway change the actual area reflecting the radiation sensed by the sensor, but the size of the reflecting area does not appreciably change. Any change effects both radiation systems in a similar manner.

L'analyseur optique utilise un système optique à un composé pour traiter un rayonnement réfléchi de manière à réduire les variations provoquées par la position changeante d'un substrat analysé dans une voie de guidage. Deux sources de rayonnement sont orientées à des angles similaires par rapport à la surface à passer au crible et le rayonnement est réparti sur une surface plus grande. Les changements de position du substrat dans la voie de guidage changent la surface effective réfléchissant le rayonnement détecté par le détecteur, mais la taille de la surface réfléchissante ne change pas sensiblement. Tout changement affecte les deux systèmes de rayonnement de manière similaire.
