Abstract

The device has a microprocessor to read and process 8 bit gray code in both X and Y directions of an object, to achieve control of the object.

Description

Magnetisch interferentievrije meetinrichting voor gevoelige opstellingen c.q. machines welke middels een optische meting met 8 parallelle lichtsluisjes die een 8 bits graycode doorgeeft waarmee de directe positiebepaling van het tussen geschoven object kan worden uitgelezen.Magnetic interference-free measuring device for sensitive setups or machines which, by means of an optical measurement with 8 parallel light barriers, transmits an 8-bit burrow code with which the direct position determination of the object moved between objects can be read.

Oeze vinding kan met name toegepast worden op plaatsen - zoals bijvoorbeeld bij een MRI-scan - waar iedere vorm van metalen of (elektrische) draden een nadelige of desastreuze invloed heeft op het resultaat. De optische (fibre-optics) meetinrichting kan op een afstand van 10 meter omgezet worden in een elektrisch te verwerken 8 bits 10 graycode waarde welke vervolgens in een microprocessor tot een reële afstandswaarde verwerkt wordt en kan worden aangewend om de aansturing van het object te realiseren. Het dubbel uitvoeren van deze uitvinding geeft een positiebepaling in zowel de X- als de Y-richting met een resolutie van slechts de dikte van de lichtstraal.This finding can be applied in particular in places - such as an MRI scan - where any form of metal or (electrical) wires has an adverse or disastrous effect on the result. The optical (fiber-optics) measuring device can be converted at a distance of 10 meters into an electrically processable 8-bit graycode value which is subsequently processed in a microprocessor to a real distance value and can be used to realize the control of the object . The dual implementation of this invention provides a position determination in both the X and Y directions with a resolution of only the thickness of the light beam.
