A diagnostic optical microscope according to the present embodiment includes at least one laser light source (11) configured to generate laser light for illuminating a sample (40) containing a light absorbing material, a lens configured to focus the laser light to be focused on the sample (40), scanning means for changing a focusing position of the laser light on the sample (40), and a light detector (31) configured to detect laser light transmitted through the sample (40) as signal light. A laser light intensity is changed to obtain a nonlinear region in which the laser light intensity and a signal light intensity have a nonlinear relation due to occurrence of saturation of absorption in the light absorbing material when the laser light intensity is maximized. An image is generated based on a nonlinear component of the signal light based on the saturation of absorption in the light absorbing material.

The application discloses a kind of gas powder slurry collaborative control method based on multi-source data fusion, it is related to industrial process control technical field, it is difficult to solve the technical problem of depth fusion visual image and physical sensor data to carry out gas-powder-slurry three-phase collaborative optimization control;Including the following steps: collecting the visual image and physical sensor data of gas-powder-slurry three-phase mixed state;With visual image as input, build visual evaluation model, output splash degree score value, dispersion uniformity score value and wetting integrity score value;Build proportion decision model, with the fusion feature vector of fusion quality evaluation index and physical sensor data as the input of multilayer perception machine, and output gas flow correction amount, powder rate correction amount and slurry flow correction amount in parallel, when three-way correction amount adjustment direction conflict, with gas carrying capacity constraint and slurry absorption saturation constraint as arbitration basis;The correction amount is output to corresponding actuator to form closed loop control.
