“…A bolometer is a type of detector originally developed in 1878 by Samuel Pierpont Langley and used for measuring the incident energy of photons via thermal effects, and typically used in astronomical measurements [180]. Building on the work of Andrews and Strandberg [181] and von Gutfield et al [182] with thin-film superconductors, a thin-film NbN bolometer was developed by Bertin and Rose in 1968 [183]. The leap from bolometer to single-photon detector was made by Gol'tsman et al in 1991 when they realized that the resistive hotspot formed by the heating effect on an incident photon could lead to single-photon detection [184].…”

Articles you may be interested inOptical gas detection using metal film enhanced leaky mode spectroscopyIn the course of investigating radiant-energy detection by high-resistance superconducting films r ~ 10 Kfl/square (0)] an unexpected enhanced mode of detection was observed at microwave frequencies.This mode was observed in addition to and differed significantly from the expected thermal or bolometer mode of detection. Since that time detailed measurements have been made of the dependence of the enhanced-mode response on bias current, incident power, temperature, and sample resistance; these are reported here. Correlation of the characteristics of the enhanced mode with the nonlinear VI (voltagecurrent) characteristics of the film is shown. This suggests that the enhanced mode is the result of a nonlinear response to currents induced in the film by the incident radiation, which explains the short wavelength cutoff associated with the enhanced mode. Physical mechanisms which might cause this response are considered and fabrication techniques for these films are presented in detail. Since the initial report, enhanced-mode responses have been observed with a responsivity per square (r= 1()4 V /W) which is thousands of times greater than the peak bolometer responsivity. At the operating point, the film has a lower output impedance [

Reçu le 10 octobre 1973) Résumé. 2014 La valeur de l'atténuation apparente d'une onde hypersonore se propageant dans un substrat, mesurée avec un bolomètre est beaucoup plus grande que l'atténuation intrinsèque de ce substrat. Nous expliquons ce fait par le déphasage introduit par le bolomètre à chaque réflexion de l'onde. L'amplitude de tension détectée par le bolomètre est proportionnelle à la puissance hypersonore « moyenne » incidente. Nous calculons la puissance absorbée en introduisant un champ électrique induit dans la couche par la vibration mécanique. La comparaison des résultats théoriques et expérimentaux permet de déduire une valeur du potentiel de déformation de l'étain, compatible avec les valeurs publiées antérieurement. Abstract. 2014 The value of the apparent attenuation of a hypersonic wave moving in a substrate, measured with a bolometer, is much higher than the intrinsic attenuation of this substrate. We explain this fact by the phase shift introduced by the bolometer at each reflection of the wave. The amplitude of the pulse of tension detected by the bolometer is proportional to the « averaged » incident hypersound power. We calculate the absorbed power by introducing an electric field induced in the film by the mechanical vibration. The comparison between the theoretical and experimental results allows us to deduce a value of the deformation potential of tin consistent with previously published values.
