Abstract: A system and a method for calibration of optical measurement devices are described. In one embodiment, the optical measurement device comprises an imaging lens, and the calibration system includes a projection light source, a lens module, and a projection element. The light emitted from the projection light source passes through the projection element and is projected by the lens module, and then captured by the imaging lens of the optical measurement device. The exit pupil of the lens module in the calibration system is coincident with the entrance pupil of the imaging lens of the optical measurement device, providing a compact and highly efficient optical calibration mechanism.

Abstract: A separate microscopy system, applied to observe a specimen positioned on a stage and further to image the specimen on an imaging device, includes an ocular-lens unit, an adjustment unit and an objective-lens unit. The ocular-lens unit has an ocular-lens optical axis, and is manipulated to make the ocular-lens optical axis perpendicular to the stage. The adjustment unit is assembled to a side of the ocular-lens unit close to the stage. The objective-lens unit has an objective-lens optical axis, and is assembled to a side of the adjustment unit close to the stage. The objective-lens unit is manipulated to be adjusted by the adjustment unit to make the ocular-lens optical axis, the objective-lens optical axis and the imaging device co-axially and perpendicular to the stage, such that the specimen can be imaged at an imaging center position of the imaging device. In addition, an adjusting method thereof is also provided.

Abstract: An automated optical measurement system and method for a near eye display are provided. A controller first controls the near eye display to display a specific pattern, then controls a displacement generation module to drive an image sensing module toward or away from an imaging module, and controls the image sensing module to capture the specific pattern to obtain focus images; and the controller performs focusing according to the focus images. Finally, the controller measures an optical characteristic of the near eye display. Accordingly, the focusing method used is to capture the specific pattern displayed by the near eye display while moving the image sensing module, and perform automatic focusing by comparing the capture results.
