    • An approach for sterilizing microorganisms at a target object employs a flashlamp system including means for generating pulses of light, and for deactivating microorganisms within the target object by illuminating the target object with the pulses of light having been generated; a photo-sensitive detector positioned so as to receive a portion of each of the pulses of light as a measure of an amount of light illuminating the target object, for generating an output signal in response thereto; and a control system, coupled to the flashlamp system and the photo-sensitive detector, for determining, in response to the output signal, whether the pulses of light are sufficient to effect a prescribed level of deactivation of microorganisms in the target object. In accordance with this approach sterilizing microorganisms involves steps of generating a pulse of light; deactivating microorganisms at the target object by directing the pulse of light having been generated at the target object; receiving a portion of the pulse of light as a measure of an amount of the pulse of light illuminating the target object; generating an output signal in response to the receiving of the portion of the pulse of light; and determining; in response to the generating of the output signal, whether the pulse of light is sufficient to effect a prescribed level of deactivation of microorganisms in the target object.
    • 用于在目标物体上灭菌微生物的方法采用闪光灯系统,其包括用于产生光脉冲的装置,以及通过用已产生的光脉冲照射目标物体来使目标物体内的微生物失活; 光敏检测器,其被定位成接收每个所述脉冲的一部分作为照射所述目标物体的光量的量度,以响应于此产生输出信号; 以及耦合到所述闪光灯系统和所述光敏检测器的控制系统,用于响应于所述输出信号确定所述光脉冲是否足以影响所述目标对象中微生物的规定水平的失活。 根据这种方法,消毒微生物包括产生光脉冲的步骤; 通过引导已经在目标物体处产生的光的脉冲来使目标物体上的微生物失活; 接收光脉冲的一部分作为照射目标物体的光的脉冲量的量度; 响应于所述部分所述光脉冲的接收而产生输出信号; 并确定; 响应于输出信号的产生,光的脉冲是否足以影响目标对象中的微生物的规定的失活水平。
