Instroduction Information optics is a new discipline developed in recent years. It has penetrated into every field of science and technology, and has become an important branch of information science. It has been applied more and more widely. This experiment has a strong practical and technical nature, and it is a group of experiments， which are equal to the theory and practice. It helps the students understand related theories in spatial frequency spectrum, optical Fourier transform, and holography. This experiment kit also helps students enhance their experimental skills. Experiments 1. Holographic photography 2. Holographic grating fabrication 3. Abbe imaging and spatial light filtering 4. Theta modulation Specifications|
