    • The present invention is an electrostatic levitation furnace which is provided with a vacuum chamber, main electrodes opposed to each other within the vacuum chamber, an auxiliary electrode moving a sample levitated by an electrostatic field generated between the main electrodes, and a laser irradiator irradiating a laser beam on a sample displaced at a predetermined position, wherein a plurality of the main electrodes are arranged at proper intervals in a vertical direction to form electrostatic field generating interspaces between the adjacent the main electrodes respectively, auxiliary electrodes are arranged to correspond to each of the electrostatic field generating interspaces, the laser irradiators are arranged both of above the main electrode positioned uppermost and under the main electrode positioned lowest so as to be opposed to each other coaxially, and the main electrode positioned midway between the uppermost one and the lowest one has a through-hole on optical path of laser beam which a sample can be passed through. The electrostatic levitation furnace, for example, when two species of samples are fused together, regardless of whether or not the samples are conductors, has the function of melting the samples being levitated individually and fusing them together while maintaining each of the temperatures of the samples, and consequently this enables to actualize a fusion in a state excluded external interference.

    • The present invention is an image pickup device provided with a CMOS camera which is provided with a telecentric lens to photograph a sample put in a levitation state at the center inside an electrostatic levitation furnace, a metal halide light source which is positioned on the opposite side of the sample from the CMOS camera to irradiate light with a wavelength of 400 to 450 nm toward the sample, and a digital signal processor which performs image processing for enhancing an edge of an image captured by the CMOS camera in real time to output a position of center of gravity of the sample put in the levitation state, where a blue filter is attached to the CMOS camera. Even if the sample becomes incandescent due to a high temperature, contrast of the sample against a background can be obtained by the image pickup device. In addition, position information required for levitation control of a sample with a complicated shape is outputted by the image pickup device so that an instant at which the sample with a complicated shape changes to a spherical shape one can be specified visually.
    • 本发明是一种摄像装置,其具备CMOS摄像机,该CMOS摄像机设置有远心镜头,以在静电悬浮炉内的中心拍摄悬浮状态的样品,位于相对侧的金属卤化物光源 来自CMOS摄像机的样品朝向样品照射波长为400至450nm的光;以及数字信号处理器,其执行图像处理,以实时增强由CMOS摄像机拍摄的图像的边缘,以输出位置 的样品置于悬浮状态,其中蓝色滤光片附着在CMOS相机上。 即使样品由于高温而变成白炽灯,也可以通过图像拾取装置获得样品与背景的对比度。 此外,由图像拾取装置输出具有复杂形状的样本的悬浮控制所需的位置信息,使得具有复杂形状的样本变为球形的样本的时刻可以被目视指定。
