Description

technical field [0001] The invention relates to the field of optical fiber sensor packaging, in particular to a high-precision multi-dimensional adjustment alignment system and method for optical fiber sensor packaging. Background technique [0002] Semiconductor materials have absorption bands for the spectrum, and, as the temperature increases, the absorption spectrum bands red shift. With this principle, accurate temperature measurement can be realized. Optical fiber sensing and temperature measurement can be realized by precisely coupling the cut semiconductor wafer with the optical fiber and monitoring the shift of the absorption spectral band of the semiconductor material. The precise coupling of the semiconductor wafer and the end face of the optical fiber is a key process for the packaging of the optical fiber sensor. Since the core diameter of the optical fiber and the size of the dicing wafer are very small, it is difficult to precisely clamp the dicing wafer. In...
