Claims (11)
1) Een spectraal beeldregistratiesysteem om verontreiniging te meten door gebruik te maken van optische methodes bestaande uit: a) Een lichtbron die licht afgeeft in het spectrum van UV tot Near Infrared; b) Detectie middelen voor het van het gemeten object terugkaatsende licht te detecteren; c) Ten minste één spectraal filter element dat selectief een vooraf vastgestelde golflengte van licht doorlaat; d) Een 'vision module' die focust op het te meten object en om ruimtelijke en spectrale data vast te leggen; e) Controle middelen om het te meten object in een of meerdere geselecteerde golflengtes te scannen; f) Een referentie database die de spectrale eigenschappen van vervuilende substanties verzameld; en, g) Analyse middelen om gevonden afwijkingen te analyseren en te vergelijken met de referentie database om zo vast te stellen welke soort vervuiling aanwezig is op het gemeten object.
2) Een spectraal meetsysteem om verontreiniging te meten volgens claim 1 waar de oppervlakte van het te meten object ofwel biologisch ofwel niet-biologisch is.
3) Een spectraal meetsysteem om verontreiniging te meten zoals beschreven in claim 2 waar het gemeten gereflecteerde licht de auto-fluorescerende emissie is van het gemeten object.
4) Een spectraal meetsysteem om verontreiniging te meten volgens claim 1 waar de detectiemiddelen bestaan uit danwel een hyperspectraal camera, danwel een multispectraal camera danwel een imaging spectrometer.
5) Een spectraal meetsysteem om verontreiniging te meten zoals beschreven in claim 3 waar het registreren van het beeld en de analyse van de contaminatie gebeurt in real time.
6) Een spectraal meetsysteem om verontreiniging te meten zoals beschreven in claim 5 waar de gehele oppervlakte van het te meten object in één keer wordt gemeten.
7) Een spectraal meetsysteem om verontreiniging te meten zoals beschreven in claim 6 waarbij de verontreiniging bestaat uit een bacteriële verontreiniging.
8) Een spectraal meetsysteem om verontreiniging te meten zoals beschreven in claim 7 waarbij het domein en de subklasse van de bacterie tot op het niveau van het serotype wordt vastgesteld.
9) Een methode om microbiologische verontreiniging vast stellen met gebruik van een systeem zoals beschreven in claim 1, bestaande uit de volgende fases: a) Het maken van een spectraal beeld van het te meten object; b) Het analyseren van het beeld om vast te stellen of er afwijkende of ongewenste substantie op het gemeten object aanwezig is; c) Het detecteren van de aanwezigheid van typische moleculen die kenmerkend zijn voor bepaalde micro organismes; d) Het vaststellen of deze micro organismes nog levend zijn of al dood; e) Het vaststellen welk type micro organisme aanwezig is, waarin onderscheid gemaakt wordt tussen prokaryoten en eukaryoten; f) Binnen het detecteren van prokaryoten en specifiek bacteriën het onderscheiden tussen de verschillende domeinen om elk 'phylum' vast te stellen en daarbinnen elke klasse en subklasse; en, g) Het binnen de subklasse vaststellen van het serotype om pathogene bacteriën te detecteren.
10) Een methode zoals omschreven in claim 9, die niet gebruik maakt van markers voor het optisch detecteren van verontreiniging.
11) Het gebruik van de methode zoals omschreven in claim 9, gebruikmakend van een systeem zoals beschreven in claim 1, in: a) land- en tuinbouw b) de voedsel- en warenindustrie c) de farmacie d) het medische werkveld e) de bouw f) het forensische werkveld g) de wetenschap h) vervoerders of transport i) eventuele restgebieden die niet onder specificatie a t/m h vallen.
