From August to October 2022, the company's product team went to Ceyear Technologies Co., Ltd. to carry out preliminary debugging, final debugging and delivery of a near-field imaging system based on a six-module vector network analyzer. The system achieves full-band real-time near-field imaging and spectroscopy from 0.11 to 1.1 THz, with real-time imaging of intensity and phase at single frequency points, and all six modules can work simultaneously — greatly reducing the time required to acquire near-field spectra.
The photos show the company's R&D personnel debugging the optical path in the Ceyear laboratory. A total of four systems were debugged, achieving simultaneous imaging with six modules. We also carried out multiple rounds of optimization on the overall optical path, and the final test results met the acceptance requirements. The last four photos show part of the test results, achieving both broadband spectroscopy and single-frequency imaging.
