Abstract

The invention provides an optical module and an optoelectronic demodulation module for a fluorescence optical fiber temperature-control system. The problem that impurities easily enter an existing optoelectronic demodulation module, consequently, the fluorescence optical fiber temperature-measuring efficiency and precision are affected is solved. The optical module comprises a mounting seat and further comprises a light-emitting diode, a lens, an optical fiber connector, a first filter and a second filter which are arranged in the mounting seat; three layers of step through holes penetrating through the rear surface are formed in the front surface of the mounting seat, and the three layers of step through holes are the first through hole, the second through hole and the third through hole,wherein the diameters of the first through hole, the second through hole and the third through hole are sequentially decreased; one end of the optical fiber connector is mounted in the first throughhole, one end of the lens is mounted in the second through hole, and the light-emitting diode is mounted in the third through hole; a first strip-shaped hole, a second strip-shaped hole and a fourth through hole which penetrate through the lower surface and communicate with one another are formed in the upper surface of the mounting seat; the first filter is mounted in the first strip-shaped hole,the second filter is mounted in the second strip-shaped hole, the fourth through hole is used for mounting of a PD, and the second filter is located between the first filter and the PD.

Description

technical field [0001] The invention belongs to the field of fluorescent optical fiber temperature control, in particular to an optical module and a photoelectric demodulation module used in a fluorescent optical fiber temperature control system. Background technique [0002] At present, the fluorescent optical fiber temperature control system is composed of a temperature demodulator, a penetrator, and an optical fiber of a temperature measuring probe containing a rare earth fluorescent substance. One end of the rare earth fluorescent substance. One end of both ends of the optical fiber is connected to the temperature demodulator, and the other end including the temperature measuring probe is placed at the measured point. The excitation light source in the temperature demodulator excites the phosphor in the probe through optical fiber transmission. At different temperatures, the phosphor emits different optical signals back to the demodulator, and then demodulates the emitt...
