And demonstration.
3. conventional observation method, cannot realize the modification as matter and information Store to the interference pattern for being formed.
4. traditional observation and measuring method, human eye is inevasible will for a long time to face strong illumination, or even cannot keep away
Exempt from the damage caused to human eye.
5. traditional observation and measuring method are realized by micro eyepiece.Student one observation when, eyes are necessary
Moment is close to micro eyepiece, it is impossible to while completing the conciliation to other parts of imaging system.
