More Information
Summary:A detection apparatus includes: a laser configured to emit laser light towards an object to be detected; a Raman spectrometer configured to receive a Raman light signal from the object; a light sensor configured to receive portions of the laser light reflected and scattered by the object under irradiation of the laser light, and to determine power of the received portions of the laser light; and a controller configured to control an operation of the detection apparatus based on the power determined by the light sensor. Further, there is provided a detection method using the above detection apparatus.
