Abstract: A measuring device used to measure a surface of an object is provided. The measuring system includes an air-flow generator, a light emitting device, and a light sensor. The airflow generator is located above the object, and is configured to inject a vapor flow onto the surface of the object and generates a condensing layer on the surface of the object. The light emitting device is located above the object and faces the condensing layer, and is configured to project a light towards the condensing layer. The light sensor is located above the object, and is configured to receive the light scattered by the condensing layer.

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 condensing system is used to generate a condensing layer on a surface of a test object. The condensing system includes airflow generating device and a passage device. The airflow generating device is used to generate condensing airflow. The condensing airflow has a dew point higher than a temperature of the surface of the test object. The passage device is connected to the airflow generating device, and the condensing airflow flows from the airflow generating device into the passage device. The passage device includes a flow-uniforming module. The flow-uniforming module includes at least one uniforming board. Each of the at least one uniforming board has at least a first hole.

Abstract: A method for inspecting a solar cell and configured to inspect a peeling state of a three-dimensional pattern of the solar cell includes obliquely illuminating the three-dimensional pattern of the solar cell using a light beam. An image of the solar cell is normally captured. An intensity of the light beam is increased to increase a contrast between the three-dimensional pattern and a shadow of the three-dimensional pattern in the image and increase a contrast between an ink pattern of the solar cell and the shadow in the image to overexpose the ink pattern in the image. Determine if the three-dimensional pattern is peeling according to the shadow of the three-dimensional pattern in the image.
