The utility model discloses a device for real-time monitoring a sol-gel solidification process. The device comprises an amplified spontaneous emission (ASE) light source, a spectrograph, an optical circulator and a fiber bragg grating (FBG) probe, wherein the output end of the ASE optical source is connected with the first port of the optical circulator; the second port of the optical circulator is connected with the connecting part of the FBG probe; the third port of the optical circulator is connected with the input end of the spectrograph; when the sol-gel solidification process is subjected to real-time monitoring, the probing part of the FBG probe is completely immersed in a to-be-tested solution. The device has the advantages that due to the facts that the ASE light source, the spectrograph, the optical circulator and the FBG probe are arranged for testing and the probing part of the FBG probe is completely immersed in the to-be-tested solution when the sol-gel solidification process is monitored in rea
