| Abstract: | To characterize and evaluate the spatial resolution of SPRITE detector, it is needed to measure the modulation-transfer-function(MTF) .Some methods of the measurement are described in previous papers. In this paper these methods are analyzed, and a novel scheme of measurement based on the plane interference fringes is described. This method can eliminate some unfavourable effects on previous measurement, induced by elements, such as light sources, targets and optical lens, and make to measuremulti-spectral MTF measurementnt. |
