    • A noncontact infrared tympanic thermometer which does not require environmental stabilization or waveguide temperature control because it utilizes an optically stabilized infrared detector for detecting the infrared energy emitted by the tympanic membrane. The optical stabilization renders the instrument insensitive to ambient temperature effects and allows it to read true tympanic membrane temperatures unaffected by the temperature of the side walls of the detector package. This selectivity is accomplished by locating a neutral density filter over half of the optical aperture of the detector package such that the neutral density filter "shadows" only one of two thermopile channels for detecting the infrared energy emitted by the tympanic membrane. The two thermopile channels are connected in series opposition such that any optical signal equally present in both channels will yield a zero net output. Since the infrared energy emitted by the walls of the detector package reach each detector equally, the effects of these emissions on the temperature measurement are eliminated. The neutral density filter prevents the energy from the tympanic membrane from falling equally on the two thermopile detectors and similarly cancelling. Instead, the resulting differential signal may be processed along with the ambient temperature signal to determine the temperature of the tympanic membrane. The infrared detector of the invention may also be incorporated into an otoscope.
    • 一种非接触红外鼓膜温度计,其不需要环境稳定或波导温度控制,因为它使用光学稳定的红外检测器来检测由鼓膜发射的红外能量。 光学稳定化使仪器对环境温度的影响不敏感,并允许其读取不受检测器封装侧壁温度影响的真实鼓膜温度。 这种选择性是通过将中性密度滤光片定位在检测器封装的光学孔径的一半上来实现的,使得中性密度滤光器仅“阴影”两个热电堆通道中的一个,用于检测由鼓膜发射的红外能量。 两个热电堆通道串联连接,使得两个通道中同样存在的任何光信号将产生零净输出。 由于检测器组件的壁发射的红外能量均匀地到达每个检测器,所以消除了这些排放对温度测量的影响。 中性密度过滤器防止鼓膜的能量均匀地下降到两个热电堆检测器上并且类似地消除。 相反,所得到的差分信号可以与环境温度信号一起被处理以确定鼓膜的温度。 本发明的红外检测器也可以结合到耳镜中。
