Surface fluorescence-enhanced two-dimensional microprobe sensing device and method and probe producing method

The invention discloses a surface fluorescence-enhanced two-dimensional microprobe sensing device, a surface fluorescence-enhanced two-dimensional microprobe sensing method and a probe producing method, belongs to the technical field of microscale measurement, and aims to solve the problems that the existing fiber probe has low optical coupling efficiency and a complex structure. The surface fluorescence-enhanced two-dimensional microprobe sensing method comprises the following steps: depositing a fluorescent substance on the end surface of a fiber to endow the end surface of the fiber with self-luminous emission capability, exciting the fluorescent substance to emit fluorescence by a wide-field illumination system, focusing the fluorescence through a lens, detecting the position of a focused spot by a CCD, and when a probe touches an object, driving the emergent end of the fiber to shift to cause shift of the position of the spot formed by focusing the fluorescence on the CCD so as tocomplete sensing.
