Abstract

The invention discloses a device based on a micro-nano fluid control reflection interference spectral imaging system and a realization method. The device comprises a micro fluid pump, a micro fluid control sample cell system, an optical microscope, a C-port optical path switcher, a CCD sensor, a spectrometer, a positioning light source, a detection light source, and a computer. The C-port optical path switcher is connected to the positioning light source, the CCD sensor, and the spectrometer through optical fibers; the CCD sensor and the spectrometer are both connected to the computer, and the computer software collects detection data and analyzes the results. According to the system, the object lens of the microscope is taken as the optical probe; compared with the conventional method that takes a detector as the probe, the system has the advantages that a fixing device for fixing a probe is not needed, the optical path integration degree of the system is improved; moreover, an imaging and positioning system is used to obtain the specific position of a sample, and thus the detection precision is improved. The morphology feature imaging of samples and reflection interference spectrum collection can be switched in real time, and thus the in-situ dynamic realtime detection of an analysis sample can be realized.

Description

technical field [0001] The invention relates to a device and a realization method based on a micro-nano fluidic reflection interference spectrum imaging system. Background technique [0002] A detection method based on micro-nanofluidic reflection interference spectroscopy imaging system is convenient, high-precision, non-contact and non-destructive detection of samples, and can directly observe and collect the surface morphology and reflection interference signals of trace samples. Among them, reflection interference spectroscopy does not require a coherent light source, which makes it simple in structure and stronger in anti-interference ability, and can be well applied to the detection of trace samples. Reflection interference spectroscopy imaging technology has more practical significance and practical value. For example, in the field of microbiology, the reflectance interference spectroscopy imaging system studies the type and quantity of microorganisms by detecting the...
