Patent number: 10962419Abstract: A method for testing a tire by interferometry in a pressure chamber of a tire testing device includes capturing phase images at different pressures in the pressure chamber, generating partial phase difference images between successive phase images, and summing the partial phase difference images to form an overall phase difference image. The pressure in the pressure chamber is changed in a first direction during a first measurement phase and the pressure is changed in the opposite direction during a second measurement phase, wherein at least one partial phase difference image from the first measurement phase and at least one partial phase difference image from the second measurement phase are included in the summation.Type: GrantFiled: April 9, 2019Date of Patent: March 30, 2021Assignee: Carl Zeiss Optotechnik GmbHInventors: Junli Sun, Xu Sun
