Bolometru cu gama dinamica de detectare reacordata a radiatiei infrarosii

Inventia se refera la receptoarele cu racire pentru radiatia infrarosie si poate fi folosita in spectroscopie, radiometrie, geofizica si astrofizica.Bolometrul contine un cristal de heliu (1) in care este introdus un element sensibil (2) conectat la aparatajul de inregistrare (4) si un sistem (3) care permite a schimba si a controla temperatura lui de lucru. The invention relates to the cooled infra-red radiation detectors and may be used in spectroscopy, radiometry, geophysics and astrophysics.The bolometer contains a helium refrigerator (1), wherein it is installed a superconductive sensing element (2), to which it is connected a recording device (4). Novelty of the invention consists in that into the refrigerator (1) it is placed a temperature control (3), and the superconductive sensing element (2) is made of a semiconductor, for example, of lead tellurium doped with thallium Pb1-xTlxTe, where x = 0,01...0,0225.
