Abstract

An optical measurement device and an optical measurement method are provided. The optical measurement device includes a test backplane, a light emitter, a center point detector and a movement device. The movement device is provided on the test backplane, and configured to carry a to-be-tested sample. The light emitter is configured to display a first center point on the to-be-tested sample, and the first center point corresponds to a center point of the test backplane. The center point detector is configured to detect a second center point and display the second center point on the to-be-tested sample, and the second center point is a center point of the to-be-tested sample. The movement device is further configured to move the to-be-tested sample, such that the first center point and the second center point coincide with each other.
