Abstract

A detection apparatus, including: a laser configured to emit laser light towards an object to be detected; a Raman spectrometer configured to receive Raman light from the object; an imaging device configured to obtain an image of the object; a light sensor configured to receive light reflected and scattered by the object under irradiation of the laser light, and to determine the power of the received light; and a controller configured to control an operation of the detection apparatus based on the image obtained by the imaging device and the power determined by the light sensor. A detection method using the detection apparatus.
