英文摘要：

2D spectral imaging based on a virtually -imaged phased array has important potential use in fabricate optical filter with high resolution and high signal noise ratio, making complicate 2D spectral processing and 2D spectral imaging. In this paper the basic theory of virtually - imaged phased array and its application in 2D spectral imaging were studied analytically and tested by numerical simulation. An experiment system was setup to achieve 2D spectral imaging. For the first time the input condition, multiple diffraction orders and the loss of virtually - imaged phased array was analyzed systematically. Ttle spectral resolution of virtually - imaged phased array and space resolution of the 2D spectral imaging are discussed, too.
