The invention provides a control method of a detection
system, and the detection
system comprises an illumination module, a first detection device, and a light splitting module and a first power adjustment module between the illumination module and the first detection device. The first detection equipment is used for detecting a first to-be-detected surface to obtain a first detection
signal, the light splitting module is used for splitting the illumination
light beam to obtain a first sub-
light beam and a second sub-
light beam, the first detection equipment can be illuminated based on the first sub-light beam, and
optical power detection can be performed based on the second sub-light beam; therefore, illumination and
light detection can be both considered, when the actual light power exceeds the preset range, the light power of the light beam penetrating through the first power adjusting module is adjusted so as to adjust the intensity of the first detection
signal, and if the intensity of the first detection
signal meets the preset condition, the light beam is detected. And the adjustment of the
optical power of the light beam penetrating through the first power adjustment module is stopped, so that the accurate adjustment of the
optical power is realized.
