    • This invention relates to a device (1) for detecting energy generated by non-radiative decay generated in a substance (2) on irradiation with electromagnetic radiation. The device (1) comprises a radiation source (6) adapted to generate a series of pulses of electromagnetic radiation, a transducer (3) having a pyroelectric or piezoelectric element and electrodes (4, 5) which is capable of transducing the energy generated by the substance (2) into an electrical signal, and a detector (7) which is capable of detecting the electrical signal generated by the transducer (3). The detector (7) is adapted to determine the time delay between each pulse of electromagnetic radiation from the radiation source (6) and the generation of the electric signal. The device (1) has a wide applicability in the fields of assays and monitoring.
    • 本发明涉及一种用于在用电磁辐射照射时检测在物质(2)中产生的非辐射衰减产生的能量的装置(1)。 设备(1)包括适于产生一系列电磁辐射脉冲的辐射源(6),具有热电或压电元件的换能器(3)和能够传导由 物质(2)变成电信号,以及能够检测由换能器(3)产生的电信号的检测器(7)。 检测器(7)适于确定来自辐射源(6)的电磁辐射的每个脉冲与电信号的产生之间的时间延迟。 装置(1)在测定和监测领域具有广泛的适用性。
