摘要: 利用虚像相位阵列 (VIPA) 的强色散能力发展而来的 VIPA 光谱仪是一种新型的高性能光谱测量装置, 兼具宽光谱覆盖范围、高时间分辨率及高光谱分辨率等优点。基于 60 GHz 自由光谱区 (FSR) 的石英 VIPA, 研 制了一台可用于红光波段光谱测量的 VIPA 光谱仪, 并测量了 633 nm 多模激光器的出射光谱。在 100 µs 的时 间分辨率下, 获得了单次 3.1 nm 测量谱宽、2.0 pm (1.5 GHz) 的高光谱分辨率, 连续 4 h 运行显示光谱漂移小于 0.50 pm。通过采用衍射光栅扫描装置、更短曝光速度的面阵 CCD 和更大 FSR 的 VIPA , 有望进一步提高光谱 仪性能。

Abstract: VIPA spectrometer, based on the strong dispersion capability of the virtually imaged phased array (VIPA), is a new type of high-performance spectral measurement technology, which has the advantages of wide spectral coverage, high time resolution, and high spectral resolution. Based on a quartz VIPA in 60 GHz free spectral region (FSR), a VIPA spectrometer for spectrum measurement in the red light band is developed, and the output spectrum of a 633 nm multi-mode laser is measured. At a time resolution of 100 µs, the output spectrum with a single measurement of 3.1 nm spectral width and 2.0 pm (1.5 GHz) high spectral resolution is obtained. And the continuous operation for 4 h shows that the spectral drift is less than 0.5 pm. The performance of the spectrometer can be further improved by using diffraction grating scanning device, area CCD with shorter exposure speed, and VIPA with larger FSR.

Key words: spectroscopy, spectrometer, virtually imaged phased array, high spectral resolution
