摘　　要：虚像相位阵列(VIPA)具有色散角度大、结构简单、成本较低等优势,对波分复用、色散补偿、脉冲整形等领域产生了重大影响。虚像相位阵列与衍射光栅结合解决了光谱混叠现象,使其在光滤波器、光谱成像、光谱处理等领域的应用成为可能。基于虚像相位阵列的光谱仪具有采集时间短、频谱测量范围宽、光谱分辨率高等优点,能应用于气体检测、分子科学、微生物学等领域,因此成为研究热点。基于ZEMAX光学软件对VIPA二维成像进行了仿真,分析了VIPA的厚度和入射角对其衍射、损耗、光谱分辨率和空间分辨率的影响,讨论了VIPA用于成像时的最佳厚度和角度,最后阐述了基于VIPA的布里渊和光频梳光谱仪,论述了不同类型光谱仪的性能和应用,并对未来进行了展望。The virtually imaged phased array （VIPA） has a significant impact on many areas such as wavelength division multiplexing （WDM）, dispersion compensating and pulse shaping due to its advantages including large angular dispersion, simple structure and low cost. Combined with diffraction grating, the spectral aliasing phenomenon is solved by VIPA to make it possible to be used in optical filter, spectral imaging and processing. The spectrometer based on VIPA has been a research topic due to its superiorities such as quick acquisition time, wide range of spectral measurement and high spectral resolution and can be applied in many areas such as gas detection, molecular science and microbiology. Based on ZEMAX optical software, VIPA 2-D imaging is simulated, the effects of the thickness and the incident angle of the VIPA on diffraction, loss, spectral and spatial resolutions are analyzed and the best imaging thickness and angle of the VIPA are discussed. Brillouin and optical frequency comb spectrometers based on VIPA are introduced. The performances and applications of spectrometers are proposed and the future development is forecasted.
