Tempered Glass Flatness and Image Deformation Tester
1. Introduction
GDT-1 tempered glass flatness and image deformation tester has
obtained the national utility model patent certificate, patent
number: ZL202021001936.3. The instrument uses an optical
non-contact probe to scan the surface topography of glass, measure
the bow bending and waveform bending lines of glass, and calculate
the peak and valley value (PV value), light focus value (OP value),
edge warping of each wave. Through multi-line scanning, the 3D
surface topography of glass, as well as the transverse deformation
curve and parameters of glass are generated. The PV value is used
to evaluate the glass flatness, and the OP value is used to
evaluate the glass image deformation. Pareto diagram and histogram
are used to evaluate the glass flatness and image deformation.
The glass is placed vertically on the sample table in front of the
equipment, and the glass is kept at rest and free from external
force. The measurement system controls the sensor to move uniformly
in the horizontal direction (X axis) to measure the displacement of
the glass, and gradually increases the horizontal slide table to
scan the glass surface with different heights (Y axis) to complete
the scanning of the entire glass surface topography. Obtain the
following curve.

And the corresponding light focus (OP) curve and peak valley (PV) value curve
And the roller wave 3D, that is, the effect of flattening the bow bend
The 3D graph can be flipped up and down, left and right, which is
easy to observe the deformation of the glass. On the right side,
different colors represent the diopter values, so that users can
intuitively understand the deformation degree of the glass.
There is also a serious bow curve perpendicular to the glass
transmission direction. This often ignored deformation is an
important factor causing image distortion of the building curtain
wall. The instrument equally spaced deformation curve in this
direction.
The figure is annotated with the amount of deformation (mm) and the
degree of bending (‰) for each line.
The optical focus (OP) and peak valley (PV) values of each point of
the measured glass were obtained by calculation
