摘要：

We have developed a photoacoustic spectrometer based on a fast responding Planckian radiator. This promising radiation source represents a matrix of 35 tiny resistors (0.500 mm x 0.357 mm) that emit their peak power in the mid-infrared wavelength region and that can be directly modulated via their current. It enables a simple, compact and robust detector for monitoring of trace gases like carbon dioxide (CO2). (C) 2002 Elsevier Science B.V. All rights reserved.
