Measurement of the Bio-part by the non-contact surface texture examination

软度和粘弹性的测量方法和测试设备尚未建立。建立了果冻、琼脂等加工食品和猪、烧、鸟肝等易腐烂食品的表面质构检测方法，并对功能设备的研制提出了要求。本研究利用空气喷射技术在被测物体表面形成凹痕。凹痕的形状是在二维激光束中测量的。通过测量被测物体上凹坑的直径和深度，提出了柔软度的测量方法。并提出了用凹坑深度的时程来检验粘弹性的方法。研制了基于它们的功能测试设备，并对柔性物件进行了测量。因此，可以显示单位载荷的表面积的柔软度。还清楚地获得了凹坑深度的蠕变和蠕变恢复。因此，这种测量方法对软测量对象的测量是可能的，并有可能证实其性能和优势。

A measuring method and a test equipment for the softness and the viscoelasticity property have not yet been established. The testing method which could measure the surface texture of measured object for processed food such as jelly and agar and perishable foodstuff such as pig roast and bird liver is established and the development of the functional equipment is desired. In this study, the dents was made to arise using air jet on the surface of measured object. The shape of the dents is measured in the two-dimensional laser beam. The measuring method of the softness was proposed by the measurement of diameter and depth of the dents which arose to the measured object. And the method for examining the viscoelasticity property by time course of the dents depth was proposed. The functional testing equipment based on them was manufactured and the flexible thing was measured. As a result, it was possible to show the softness at the surface area per unit load. Creep and creep recovery for the depth of the dents were clearly also obtained. Therefore, the measurement of soft measured object was possible for this measuring method, and it was possible to confirm the performance and the advantage.
