Problems solved by technology

[0006] Raman spectroscopy is very sensitive to test conditions. The acquisition lens of the existing optical probe has a fixed focal length, but in actual measurement, especially in live detection, it is often impossible to ensure that the light source is accurately focused on the measured sample, resulting in the accuracy of the measurement results , stability and repeatability are not ideal, and cannot meet the requirements of live detection, dynamic real-time monitoring, and rapid detection
[0007] In addition, the optical probes of existing blood glucose monitors are not designed and developed specifically for living body detection, especially for human body detection. They are not suitable for human body detection in terms of shape, specification, or operation, and cannot meet the needs of living body detection. Requirements for convenience and comfort
