Abstract

The invention provides a probe with image transmission and chemical sensing functions, a manufacturing method of the probe and an optical system comprising the probe. The probe with image transmission and chemical sensing functions comprises an image transmission optical fiber bundle and a self-focusing lens which is arranged on the end part of the image transmission optical fiber bundle, whereinthe surface of the self-focusing lens is plated with a sensitive film. The probe with image transmission and chemical sensing functions which can be used for measuring the concentration of chemical ions and observing the physical shape of the inner surface of a cavity, has high flexibility, can be directly inserted into a human body or cells, is difficult to fracture and has a wide range of application, and the manufacturing method of the probe and the optical system comprising the probe are provided.

Description

Technical field [0001] The invention belongs to the field of optical detection, and relates to a sensing probe and an optical system based on the probe, in particular to a probe that combines image transmission and chemical sensing, a manufacturing method of the probe, and an optical system containing the probe. Background technique [0002] Bio-optical sensors are generally composed of biometric components, optical conversion components, mechanical components and electrical components. Among many types of optical biosensors, optical fiber sensors occupy an important position due to their anti-electromagnetic radiation, anti-electromagnetic interference, and anti-corrosion characteristics. The optical fiber sensor is also a highly miniaturized device, and miniaturization is very necessary for interventional monitoring. At the same time, very few samples are required for detection. Another feature of the fiber optic sensor is that it can be used for long-distance sensing, coupled...

Problems solved by technology

Among them are NewPort Green, FluoZin-1, FluoZin-3, ZnAFs, Zinpyr, Zinquin, etc., but the prices of these fluorescent indicators are very expensive

On the other hand, most of the existing zinc ion sensors use absorption spectroscopy, which limits the application range of detection.

For example, the detection of zinc ions in some remote locations such as internal organs of the human body cannot be achieved by absorption spectroscopy
