Abstract

Αποκαλύπτονται μέθοδοι και συσκευή δια την κατασκευή οπτικά σταθεροποιημένων υπερύθρων καπνογράφων χωρίς φωτοφράκτη. Οι καπνογράφοι της παρούσης εφευρέσεως δίδουν την απόλυτο περιεκτικότητα των συστατικών του συστατικού αερίου ρεύματος ενός ασθενούς χωρίς προβλήματα θερμικής μεταθέσεως που κανονικά παρουσιάζονται σε θερμοφίλους ανιχνευτάς και έτσι δίδεται μια διάταξη με μεγάλο βαθμό ακριβείας. Η παρούσα εφεύρεσις εξαλείφει την ανάγκη δια μηχανικό διάφραγμα δια να διαμορφώνουμε την προσπίπτουσα υπέρυθρο δέσμη και την ανάγκη μιας διαμορφωμένης πηγής αυξάνοντας τοιουτοτρόπως την αξιοπιστία και τον χρόνο ανταποκρίσεως των αποκαλυπτομένων διατάξεων. Οι καπνογράφοι οι οποίοι ουσιαστικά δεν επηρεάζονται από μεταβολές της θερμοκρασίας περιβάλλοντος υπό την οποίαν αυτοί λειτουργούν, δίδονται δια συνδέσεως ζευγών οπτικά διηθημένων θερμοφίλων εν σειρά και δια επεξεργασίας του προκύπτοντος διαφορικού ζεύγους. ω
