Optical fiber detecting probe head for portable raman spectrometer

Abstract

The invention relates to an optical fiber detecting probe head, in particular to an optical fiber detecting probe head for a portable raman spectrometer. The optical fiber detecting probe head for the portable raman spectrometer is characterized by comprising a probe head component and a plurality of collecting optical fibers (9), wherein one ends of the collecting optical fibers (9) are simultaneously connected with the probe head component, and another ends of the collecting optical fibers (9) are simultaneously connected with an FC (fiber channel) probe head; and the optical fiber detecting probe head for the portable raman spectrometer further comprises an exciting optical fiber (10), wherein one end of the exciting optical fiber (10) is connected with the probe head component, and another end of the exciting optical fiber (10) is connected with an SMA905 interface. Therefore, the optical fiber detecting probe head has the advantages that the optical fiber detecting probe head is mini, efficient, and suitable for the clinic detection of the early digestive tract cancer, and the raman light collecting efficiency at the side wall of the upper digestive tract can be improved.

Description

Technical field [0001] The invention relates to an optical fiber detection probe, in particular to an optical fiber detection probe used in a portable Raman spectrometer. Background technique [0002] As a non-destructive and rapid analysis technique, Raman spectroscopy has been widely used in medical detection and clinical diagnosis. However, the detection of upper gastrointestinal cancer with a high incidence is still in the research stage of early diagnosis in vitro. The application of Raman spectroscopy in clinical medical diagnosis depends on an efficient and convenient collection of Raman light systems, and Raman fiber detection probes are an important part of this system. At present, the commercialized Raman fiber optic probes are all applied in the industrial field, and their large size is the biggest disadvantage that they cannot be used for in-situ detection in vivo. There are also reports of small-volume Raman fiber optic detection probes for in-situ Raman detection i...
