Abstract: Atom optics has seen fast development and vast achievements, and has wide application prospects. The basic principles of the manipulation and control of cold atoms using magnetic and laser fields are briefly introduced, followed by a detailed review of recent progress of geometric and wave atom optics as well as potential applications and the development of atom optics devices Topics include the reflection of atom beams and mirrors, the deflection (refraction) and focusing of atom beams and lenses, the diffraction of atom matter waves and gratings, atom interferometers, and atomic holography.
