The invention puts forward equipment for scanning facial
porosity of rock and belongs to the field of
chronology. Pores of rock are filled with a fluorescent material. The equipment comprises an object stage, an objective lens, a polariscope, a focusing lens, a
laser scanning unit, a
fluorescence incident pore-plate, a photoelectric
signal amplifier and a control
processing unit. The object stage can move up and down along the vertical direction. The objective lens, the polariscope and the focusing lens are successively arranged from bottom to top above the object stage. The
laser scanning unit is arranged at one side of the polariscope and can move. The
fluorescence incident pore-plate and the photoelectric
signal amplifier are successively arranged from bottom to top above the focusing lens. The photoelectric
signal amplifier can receive a
fluorescence signal from a
laser-activated fluorescent material and convert the fluorescence signal to an electrical signal. The control
processing unit can control up-down movement of the object stage, control operation of the
laser scanning unit and receive and process the electrical signal from the photoelectric
signal amplifier. The invention also puts forward a corresponding method. According to the equipment and the method, facial
porosity of rock can be observed accurately and conveniently.
