  • Automated online measurement of glass part geometry
    Patent number: 7710558
    Abstract: An apparatus which measures a size and a shape of a transparent sheet includes a conveyor, a lighting apparatus, an imaging device and a process controller. The conveyor moves the transparent sheet. The lighting apparatus projects light onto the transparent sheet. The imaging device receives reflected light reflected from the transparent sheet. A thickness is input into the process controller. A sheet temperature from a sheet temperature sensor and/or a structure temperature from a structure temperature sensor are output to the process controller. An image is output from the imaging device to the process controller. The process controller outputs the size and the shape of the transparent sheet. The outputs from the process controller are used to adjust machine tools used to fabricate the transparent sheet.
