Περίληψη
Η παρούσα εργασία, με τίτλο Λήψη δεδομένων φασματογράφου υψηλής διακριτικής ικανότητας έχει ως αντικείμενο μελέτης της την φασματοσκοπική ανάλυση και τις δυνατότητες εξέλιξής της.
Πιο συγκεκριμένα, η μελέτη έγκειται στη φασματοσκοπική συσκευή ανάλυσης που διαθέτει το Τμήμα Ηλεκτρολογίας του Ανώτατου Τεχνολογικού Ιδρύματος Ηρακλείου. Πρόκειται για ένα σύστημα υψηλής διακριτικής ικανότητας το οποίο διαθέτει έναν φασματογράφο, έναν φωτοπολλαπλασιαστή και μια πολυκάναλη κάρτα συλλογής δεδομένων. Πρόθεσή μας είναι, η κάρτα που περιέχεται στην υπό μελέτη συσκευή φασματοσκοπικής ανάλυσης, με την κατάλληλη προσαρμογή σε υπολογιστή, να κινεί το βηματικό κινητήρα μεταβολής του μήκους κύματος του φασματογράφου, μέσω του ήδη υπάρχοντος ελεγκτή, έτσι ώστε στη συνέχεια να “συλλαμβάνει”, να απεικονίζει αλλά και να αποθηκεύει το ηλεκτρικό σήμα εξόδου του φωτοπολλαπλασιαστή. Επιπλέον, θα παρέχεται η δυνατότητα για αυτόματη εξαγωγή της φασματικής απόκρισης αναφορικά με την υπό μέτρηση φωτεινή πηγή. Η πραγμάτωση των στόχων μας θα επιτευχθεί διαμέσου της υλοποίησης μιας συσκευής η οποία να μπορεί να ανιχνεύει το σημείο όπου η εναλλασσόμενη τάση του δικτύου περνάει από το μηδέν.
The subject of this study is spectroscopic analysis and its evolutional capabilities. More specifically, we dealt with the spectroscopic-analysis device which lies in the ''Laboratory power Electronics'' in the department of Electricians of the Technological Institute of Crete. It comes to a high-distinctive-ability system which has a monochromator that analyses incoming light into individual wavelengths, a photomultiplier which is useful in the conversion of analyzed radiation into electronic signal, visual arrangements for the controlled light-path by the light source being under study, low and high voltage suppliers, as well as a multitrack data collection card. Our concern in this project was to make feasible that when adjusted to a computer suitably, the card included in the spectroscopic analysis device being under study, should be able to move the spectrograph's wave-length-metabolic stepper motor, through an already existent controller, so that the former can conceive controllably, depict but also store the photomultiplier’s electrical signal. An additional objective in this study was the ability of instant export of spectral response, with respect to the light source being under measurement. Moreover there was a particular focus on the detailed data storage in a spreadsheet archive, which includes pictures, diagrammes and the parameters of the conduction, as well as comments to each measurement. The processes followed with respect to the accomplishment of the aims this paper set, were performed using the Labview programming language : a suitable programming code was implemented through focused work-interventions, so that the results recorded while studying the data would be the greatest possible.
