Abstract

The invention relates to an upper rectification phosphorescence immune chromatographic test paper testing system which comprises: the lighting system comprises an exciting light source and an optical fiber beam, a collimation lens, a dichroic mirror and a front mirror group on the output light path of the exciting light source, wherein the test paper is on the object plane of the front mirror group; the angle between the reflecting side of the dichroic mirror and the light shaft is 45 deg.; the imaging system is formed by a front mirror group with the same light shaft, a dichroic mirror, a light filter and a rear mirror group; the phosphorescence image receiver is CCD which is on the image plane of the rear mirror group; the output end of CCD is connected with the data collecting circuit which is connected with a control system.

Description

technical field [0001] The present invention relates to up-conversion phosphorescence labeling technology, in particular to an up-conversion phosphorescence immunochromatography test strip detection system. Qualitative and quantitative detection of various target objects such as illegal drugs. Background technique [0002] Up-conversion phosphorescence technology is a new type of labeling technology developed based on up-conversion phosphorescent materials. The conversion of long-wavelength radiation into short-wavelength radiation by special mechanisms is called upconversion. A special material having an up-converting phosphorescence phenomenon is called an up-converting phosphorescent material (Up-Converting Phosphor hereinafter referred to as UCP). When excited with infrared light, the material emits visible light at a wavelength much shorter than the excitation light. If the up-converting luminescent particles and bioactive molecules are connected by covalent bonds to...

AI Technical Summary

Problems solved by technology

[0007] 2. High requirements on the stability of the excitation light source

Since the signal acquisition is completed through long-term mechanical scanning, the acquisition of the signal on the test strip cannot be completed synchronously, so the instability of the output performance of the excitation light source will affect the detection results

[0008] 3. Signal reliability is affected

During the scanning process, the laser may vibrate due to mechanical movement, resulting in fluctuations in illumination intensity and affecting acquisition

[0009] 4. Complicated operation

In the process of data processing, manual intervention is required, which affects the speed and increases the complexity of the operation

[0010] 5. Waste of resources

Control and data processing through PC computer actually only utilizes a small part of the many functions of PC computer, while other functions cannot be used but still occupy processing time and resources, resulting in waste of time and power consumption

The operating speed is greatly limited, and due to the large power consumption, dry batteries cannot be used for power supply, so that the instrument cannot work independently
