Abstract: The present invention relates to a volcanic ash detection method using an infrared channel and a method of deriving a characteristic value of a volcanic ash for detecting the volcanic ash using an infrared channel observation data of a satellite while deriving the characteristic value of the volcanic ash. The volcanic ash detection method using an infrared channel and the method of deriving a characteristic value of a volcanic ash according to the present invention convert the radiation observation data, which is observed from a detection sensor of a satellite, to a brightness temperature and reflectance of each channel, determine as an volcanic ash pixel when a condition of a brightness temperature difference of an infrared channel, in which a wavelength range is 11μm, 12μm, and the condition of the brightness temperature difference of the infrared channel, in which a wavelength range is 11μm, 12μm, 3.7μm, in an image pixel of a satellite image is simultaneously satisfied after a cloud pixel and a sand dust pixel are removed, determine an elevation of the volcanic ash using weather analysis data, create a theoretical amount of radiation according to a characteristic of the volcanic ash in the form of a table by using public volcanic ash model data and derive an optical thickness and a size of a volcanic ash particle by comparing the finally determined brightness temperature value of the volcanic ash pixel to the table. According to the present invention, a volcanic ash component in the atmosphere can be automatically detected in near-real-time from night and day by using the satellite, so the volcanic ash can be more accurately detected by minimizing interference from the sand dust component such as yellow dust, and the elevation of the volcanic ash, the optical thickness of the volcanic ash and the particle size (effective radius) of the volcanic ash can be simultaneously analyzed.

Abstract: The present invention relates to an optical alignment device of a LIDAR system including a telescope, a laser, a beam separator, a pin hole, a collimating lens, and an oil film reflector. The telescope includes first and second mirrors and is installed in the lower side of a frame. The laser is installed on the rear side of the telescope and irradiates the telescope with laser light. The beam separator is installed on the front side of the telescope and divides the laser light into two beams. The pin hole is installed between the bema separator and the telescope and forms a focus of the laser light. The collimating lens is installed between the pin hole and the beam separator and makes the laser light passing through the pin hole with parallel light and collects the laser light returned. The oil film reflector reflects the laser light passing through the beam separator. According to the composition, an optical system is easily accurately aligned without a disassembly work of the optical system for inspecting the optical alignment during observation or when the optical system for the atmospheric observation is installed. Accurate optical alignment between channels can be formed in a short time regardless of the number of channels of an optical reception terminal.
