摘　　要：在虚拟成像相位阵列光谱特性基础上,对激光频率梳同步定标的千万分辨率虚拟成像相位阵列光谱仪器进行了可行性研究,通过数值计算,给出了针对不同应用的两个方向设计思路;并采用一般的常见参数,模拟出了满足同步定标千万分辨率光谱仪的二维光谱图.最后,对该类装置几个代表性应用领域及应用中的主要性能进行了简要讨论.The feasibility of a 10-million-resolution virtually imaged phased-array spectrograph with a laser frequency comb as the calibration source is studied based on the virtually imaged phased-array dispersion characteristics.The numerical simulations propose two design schemes under extreme conditions with respective pros and cons.A simulated 2 D spectral image is provided that satifies the the resolution of 10 million with simultaneous calibration using general parameters.Finally,the performance of such spectroscopy in some foreseeable applications is discussed briefly.
