Abstract
Operations related to error reduction in measurement of samples of materials may include operations in which a first distance measurement may be obtained between a first probe and a first surface of a sample at a first time mark. Additionally, the operations may include obtaining a second distance measurement between a second probe and a second surface of the sample at a second time mark. Operations may further include obtaining a third distance measurement between the first probe and the first surface of a sample at a third time mark, and determining a fourth distance measurement between the first probe and the first surface of the sample at the second time mark. In addition, the operations may include determining a thickness of the sample, including an error term due to vibration of the sample. The error term may be discounted from the thickness of the sample.
