Title:
特性測定装置
Document Type and Number:
Japanese Patent JP7051207
Kind Code:
B2
Abstract:
To provide a characteristic measuring apparatus allowing the reduction in measurement time of an object and the improvement of measurement accuracy.SOLUTION: The characteristic measuring apparatus includes: a storage unit storing a conversion curve or conversion table showing the correspondence between the amount of an object and a time change amount of an output signal of an elastic surface wave sensor 5; and a detection unit 6 for calculating the time change amount of at least one of the phase and amplitude at a predetermined time interval from the measurement start of the object. On the basis of the calculation result of the time change amount, the characteristic of the object is determined using the conversion curve or conversion table.SELECTED DRAWING: Figure 1
