F-ST1060 modulation experiment Feartures of the instruments : θ modulation technique is a clever application of Abbe imaging theory it will transfer the orginal image into grating modulation image distributed at a certain angle insert the modulation image into the potical and pursue appropriate spatial flitering treatment with white light illumination to achieve pseedo-color coding and then color output image is obtained , commplete set of equipment optical experiment guide light source, lens fourier lens θ films, the spectrum holder , frosted glass and so on ,
