F-JGSB1150 Laser Speckle Measurement of Transverse Minor Displacement
Experiment contents and related subjects: 1.Observe the laser speckle patterns, understand the reason and characteristics of speckle. 2.Grasp the measurement methods and principles of small displacement with double exposure. 3.Verify the relation formula between displacement and speckle image through actual measurement. Features of the instruments: 1.Using semiconductor laser (650nm, 4mW) as the light source. 2.Self arranging optical path to shoot the speckle patterns and to measure, analyse the speckle pattern. Complete set of equipment: Optical experiment guide, semiconductor laser, beam expander lens, collimating lens, dry plate rack, rack one-dimensional displacement, laser power indicator, frosted glass and etc..
