    • A radiation clinical thermometer for making no-contact measurements of the temperature of the eardrum, comprising a light receiving section (17) for receiving only infrared rays radiated directly from the eardrum and/or its vicinity, a signal processing means (4) for calculating the temperature from the output of the light receiving section, and an annunciation means (18) for annunciating the calculated temperature. Because the thermometer is not influenced by the heat radiation from other than the eardrum and/or its vicinity, the temperature variation of the probe (1) does not cause measurement errors and therefore an accurate temperature measurement can be made. When viewed at the cross section of the thermometer including the optical axis of the light collecting element, the infrared light receiving element is placed in a triangle formed by three lines connecting three points, and an intersection between the optical axis of the light collecting element and an optical path where a line drawn from the edge of the light collecting element in such a way as to be tangent to the inner wall of the probe on the same side as the edge of the light collecting element with respect to the optical axis extends from an imaginary end where the line intersects the end surface of the probe and passes through the edge of the light collecting element on the same side as the imaginary end point with respect to the optical axis to reach an image point of the imaginary end point by the light collecting element. The remaining two points are two image points of the light collecting element at the imaginary end point.
    • 一种辐射体温计,用于进行鼓膜温度的非接触式测量,它包括仅接收从鼓膜和/或其附近直接辐射的红外线的光接收部分(17);信号处理装置(4),用于计算 来自光接收部分的输出的温度,以及用于通知所计算的温度的报告装置(18)。 由于温度计不受鼓膜和/或其附近以外的热辐射的影响,所以探头(1)的温度变化不会引起测量误差,因此可以进行精确的温度测量。 当在包括聚光元件的光轴的温度计的横截面处观察时,红外光接收元件被置于由连接三个点的三条线形成的三角形中,并且聚光元件的光轴与 其中从集光元件的边缘以相对于光轴在与集光元件的边缘相同的一侧上与探头的内壁相切的方式画出的线从光路延伸的光路从 所述线与所述探针的端面相交并且穿过所述聚光元件的与所述虚拟端点相同侧的边缘相对于所述光轴的假想端,以通过所述虚拟端点到达所述虚拟端点的像点 集光元件。 剩下的两个点是在虚构端点处的光收集元件的两个图像点。
