Abstract: One aspect is a scanning light detection and ranging (LiDAR) having an optical structure which shares a transmitting and receiving lens. In one embodiment, the LiDAR includes a hole mirror disposed to have a first angle with respect to a horizontal surface and including a hole and a reflecting surface and a beam source configured to output a pulsed laser beam from one side of the hole mirror toward the hole. The LiDAR also includes a transmitting and receiving lens configured to generate a collimated beam to move the pulsed laser beam which passed through the hole toward a measurement target, receive a beam reflected from the measurement target, and transmit the reflected beam to the hole mirror. The LiDAR further includes a beam detector disposed to face the reflecting surface of the hole mirror and configured to receive the beam reflected from the hole mirror and convert the reflected beam into an electronic signal.

Abstract: An ultraviolet-ray (UV) sensor is disclosed. In one embodiment, the UV sensor includes a piezoelectric material, a sensing film arranged on the piezoelectric material and senses ultraviolet rays, an elastic wave input unit arranged on one end of the sensing film on the piezoelectric material and provides the sensing film with an elastic wave generated based on an electrical signal and an elastic wave output unit arranged on the other end of the sensing film on the piezoelectric material and senses a change in frequency of the electrical signal generated based on the provided elastic wave. The UV sensor improves sensitivity of the sensor by enabling the particles having large surface areas due to their characteristics to react with a larger amount of ultraviolet rays. the UV sensor can secure price competitiveness since the UV sensor measures a change in frequency of the elastic wave using zinc oxide (ZnO) nanoparticles.

Abstract: The present invention relates to a photosensitive coating composition, a conductive coating film using the photosensitive coating composition, and a method for forming the conductive coating film. The present invention provides photosensitive coating composition for forming a conductive coating film, the composition containing a conductive nanomaterial and a photosensitive material. Further, the present invention provides a conductive coating film formed on a substrate, the conductive coating film formed using a photosensitive coating liquid. Here, after the photosensitive coating liquid is coated on the substrate, an exposed region and a non-exposed region are formed by exposure and washing, wherein the non-exposed region has at least two times the conductivity of the exposed region.
