Abstract: A surface measurement system is configured to measure a sample with a low reflectivity surface. The surface measurement system includes a condensation device and a measurement device. The condensation device is configured to form a liquid layer on the surface of the sample. The condensation device includes a chamber, a temperature controlling gas source, and a humidification gas source. The chamber is configured to accommodate the sample. The temperature controlling gas source is connected to the chamber to provide temperature controlling gases to the chamber, so as to control the temperature of the sample. The humidification gas source is connected to the chamber to provide water vapor to the chamber, so as to form the liquid layer on the surface of the sample. The measurement device includes a plate, a light source, and an image capturing device.

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.
