摘要：
Measuring the three-dimensional point spread function (3D PSF) of imaging spectrometers is a challenging task since it requires a small, monochromatic and bright source. Here we introduce a powerful and practical new approach for 3D PSF measurement on the basis of a bright virtual monochromatic point-like source, which is formed by a collimated light beam and a convex spherical mirror. The effectiveness of the proposed methodology is demonstrated and discussed through 3D PSF measurements of an acousto-optic tunable filter based imaging spectrometer.
