This invention relates to a super-short optical pulse measurement device based on the SPIDER technology, which applies a pulse dispersimeter with adjustable dispersion composed of two isosceles right-angle prisms of same size to generate chirp pulses, so that, this invention can test photo-pulses from several femtoseconds to several hundreds of femtoseconds, and the pulse dispersimeter is polarized and no light to incident photo-pulses and its dimension is not limited by the spectrum width of photo-pulses.
