S4：The regulation intensity of light source, projects with making laminated film complete display on microspur imaging device；
S5：The height of controllable register, makes baffle plate move down the part light source for gradually blocking and projecting on microspur imaging device, and
And intersection point is formed with the image in irradiation laminated film direct projection to microspur imaging device, depicted successively on image capturing system
These intersection points；
S6：Image capturing system depicts more point by the binary conversion treatment to projected image on image capturing system,
It is sequentially connected the plurality of point and obtains the contour curve after laminated film deformation；
S7：Image capturing system calculates the curvature of contour curve, and using the pressure in known sample cell, obtains in sample cell
Pressure and film deformation curvature between corresponding relation.
