    Abstract: A solid surface wettability determination method is disclosed. A liquid is sprayed on a surface of an object. A light beam is projected toward the surface, wherein the light beam is reflected by the liquid on the surface to generate a reflected light. The reflected light is received by an optical detector, and the optical detector outputs a determining signal related to a wettability of the surface according to the reflected light. A corresponding signal-angle relation is selected from a database according to type of the liquid and material of the object. The contact angle of the liquid on the surface is obtained by applying the determining signal to the corresponding signal-angle relation.

    Abstract: A textile detection module is suitable for detecting a test specimen. The textile detection module includes a height sensor, an excitation light source, an optical detector, and a focuser. The height sensor is suitable for measuring a height of the test specimen to generate a height signal. The excitation light source provides an excitation light beam. The optical detector is disposed on a transmission path of the excitation light beam and is suitable for receiving the excitation light beam and emitting the excitation light beam along the optical axis and receiving a detection light beam to generate a detection result. The focuser is disposed on the transmission path of the excitation light beam emitted by the optical detector. The focuser includes a focus lens suitable for converting the excitation light beam into a focused excitation light beam. The focused excitation light beam is transmitted from the focuser to the test specimen to generate the detection light beam, wherein the focuser adjusts a position of the focus lens according to the height signal. The height sensor measures the height of the test specimen at a first position of the conveying path, the optical detector performs optical detection on the test specimen at a second position of the conveying path, and the test specimen moves from the first position to the second position along the conveying path.

    Abstract: A tapered optical needle includes a tapered light-transmissive needle and a surface plasmon wave transport layer. The tapered light-transmissive needle has a first tip, a bottom, and a curved surface connecting the first tip and the bottom. The surface plasmon wave transport layer is disposed on the curved surface and covers the first tip, wherein the surface plasmon wave transport layer has a curved slit structure. The curved slit structure includes a plurality of curved portions arranged from the first tip to an edge of the bottom and located between the first tip and the edge of the bottom, and extending directions of the curved portions are different to a direction from the first tip to the edge of the bottom.
