peer agreement (net): +2(profile) projection system Explanation: Les projecteurs de profils sont des appareils de mesure optique projetant une image de profil d’une zone ou d’une caractéristique d’une pièce sur un écran. Ils existent en deux versions : horizontale ou verticale. La projection horizontale est utile lors d’un contrôle de composants cylindriques. La projection verticale est efficace lors de contrôle de petits composants. Le projecteur sert également dans la production de petits articles en métaux, plastique, caoutchouc ou électronique. https://www.blet-mesure.fr/mesures/projecteurs-de-profils.ht... Le projecteur de profil est un appareil de mesure optique utilisé en métrologie et dans le contrôle qualité. Cet appareil permet de projeter l'ombre d'une pièce à mesurer sur un écran. C'est cette ombre qui est ensuite utilisée par l'opérateur pour effectuer les mesures. https://www.plastiform.info/controle-dimension/projecteur-de... A profile projector is an optical measuring instrument used in metrology and quality control. This device allows the shadow of the part to be measured to be projected on a screen which is then used by the operator to perform the measurements.x It’s the principle of Chinese shadows, but it still works very well today https://www.plastiform.info/en/dimension-control/profile-pro... Profile projectors (optical comparators) are a type of optical measuring instrument. The measurement principle is similar to that of optical microscopes. The target is placed on the stage, and a light is shined [sic] on the target from underneath. This causes the target's profile, or shadow, to be projected on the screen. https://www.keyence.co.in/ss/products/measure-sys/measuremen... -------------------------------------------------- Note added at 29 mins (2024-02-22 15:50:14 GMT) -------------------------------------------------- Although this much can be seen on the site, "Projection head. The projections heads are optical instruments which make it possible to check, by comparison or by measurement, the precision of the shapes ..." the actual document cannot be accessed (404 Not Found Error) https://www.marcel-aubert-sa.ch/Specialties_watchmaking_en.h... Presumably your 1950s technology has continued through to this day in the shape of instruments such as this "optical comparator (profile projector" - https://www.keyence.com/products/measure-sys/image-measure/ -------------------------------------------------- Note added at 31 mins (2024-02-22 15:52:28 GMT) --------------------------------------------------  |
