ZWP grating diffraction imaging instrument and its application in optics experimental courses teaching

Based on the spectral combination function of grating and the bi-grating diffraction imaging effect, ZWP Grating Diffraction Imaging Instrument has been designed and developed, and some new experiment courses about grating diffraction have been set up for college students using the instrument. The new grating experiments are aimed to help students understand the comprehensive knowledge of grating diffraction. Also, it is a good training to improve student’s hands-on abilities. The instrument has been used by more and more universities.
