    • There is provided a photothermal conversion measuring instrument which can measure change in property caused by thermal effect in a sample with high sensitivity and high accuracy by a simple structure. The instrument includes a current control circuit for sequentially switching output light of a plurality of excitation light sources each outputting excitation light having a different wavelength band so that one of the output light is irradiated to the sample, a light detector for interfering measurement light transmitted through the sample with reference light and detecting the intensity of the interference light, and a signal processor for extracting the same cycle components as the switching cycle of the output light switched by the current control circuit from a signal of the interference light intensity obtained from the light detector and for obtaining a difference of signal values corresponding to each of the excitation light based on the extracted signals.

    • A vein authentication apparatus registers vein data and vein characteristic amounts, determines comparison order at vein data identification time by sorting records in descending order of degree of similarity on the basis of vein characteristic amounts for comparison and the registered vein characteristic amounts, and makes vein data comparison in accordance with the comparison order. The vein authentication apparatus uses 32 frequencies obtained by performing a Fourier transform, 12 angles obtained by performing a Fourier transform, curvature directions in 36 angle areas, segment directions in 18 angle areas, and a vein amount as the vein characteristic amounts. By doing so, the accuracy of comparison order is improved and a comparison using a record for which a degree of similarity is low can be omitted. As a result, the speed of a comparison process and the maximum number of pieces of living body information which can be registered can be increased.
    • 静脉认证装置记录静脉数据和静脉特征量,通过基于用于比较的静脉特征量和登记的静脉特征量的相似度的降序对记录进行排序来确定静脉数据识别时间的比较顺序,并使静脉数据 按照比较顺序进行比较。 静脉认证装置使用通过执行傅里叶变换获得的32个频率,通过傅里叶变换获得的12个角度,36个角度区域中的曲率方向,18个角度区域中的分段方向,以及作为静脉特征量的静脉量。 通过这样做,可以提高比较顺序的精度,并且可以省略使用相似度低的记录的比较。 结果,可以增加比较处理的速度和可以登记的最大生物体信息数量。
