Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0030] An ASE light source test system, such as figure 1 As shown, including ASE light source test integration equipment, spectrometer and test computer. ASE light source test integration equipment supplies power to the light source under test and collects optical power information through photodetectors, and at the same time converts the collected driving current and optical power of the light source under test into digital quantities through the RS232 serial port or Bluetooth communication interface and transmits them to the test computer . ASE light source test system software is installed in the test computer, and the test software is connected with ASE light source test integration equipment an...

Abstract

The invention relates to an ASE light source test system. The system comprises ASE light source test integrated equipment used for supplying power to a tested light source and acquiring light power and driving current information; and a test computer connected with the ASE light source test integrated equipment. The ASE light source test integrated equipment comprises a power supply module, a control circuit board and a plurality of detectors, wherein the power supply module is expanded to multi-path output through the control circuit board, and the detectors are connected with tail fibers ofa tested ASE light source. Eight light sources can be tested at the same time, each channel operates independently and does not interfere with each other, and the test capability is improved. Moreover, in hardware design, functions of a microprocessor are fully utilized, chips such as an external ADC are avoided, the design is simplified, and the development cost of test equipment is reduced.

Description

technical field [0001] The invention belongs to the technical field of ASE light sources, in particular to a multifunctional testing system for testing driving current, output power and spectrum of ASE light sources. Background technique [0002] ASE (Amplified Spontaneous Emission) light source is a wide-spectrum light source based on erbium-doped gain fiber amplified spontaneous emission. Because of its output with high stability of average wavelength, wide spectrum, high output power and other characteristics, it is widely used in fiber optic gyroscopes, fiber optic sensors, communication WDM System and DWDM system, spectral measurement, low-coherence optical imaging and other fields have been widely used. Especially in the interferometric fiber optic gyroscope, compared with the widely used SLD light source, the high output power of the erbium-doped fiber light source can further improve the signal-to-noise ratio of the gyroscope system, and the characteristics of wide s...
