title: Improvement of pyroanalyzer sensitivity for infrared and far-infrared studies.
abstract: By using a [(signal) + (noise)] - (noise) digital averaging technique in order to reduce the offset drift, an improvement of about a factor 100 has been obtained in the sensitivity of a pyroelectric detector array (PDA). Different applications of the apparatus for measurement of infrared and far-infrared beam characteristics are also presented.
