Three-dimensional Internal Information Acquisition System Based on Consecutive Precision Machining and Cross-sectional Observation – Development of the System and Its Applications –
An automated system was developed to acquire three-dimensional information from metallurgical and biological specimens. The system is based on consecutive precision machining and crosssectional image recording. In the system, face milling by a single crystal diamond tool is used for high precision machining, and an optical microscope is used for cross-sectional image recording. The system enabl...
متن کاملDirect observation and image-based simulation of three-dimensional tortuous crack evolution inside opaque materials.
We present a combined novel methodology to study the three-dimensional complex geometry of a tortuous crack and identify the essential features of the crack and its propagation inside a heterogeneous material. We find that some severe damage events occur unexpectedly below a local mode-I crack within the sample; we realize that the severe plastic zone of the local mode-I crack is shifted down b...
متن کاملObservation of Microorganism Galvanotaxis using High-speed Three-dimensional Tracking System
Our goal is to utilize microorganisms as micro-robots by using galvanotaxis (locomotor response to electrical stimulus). To reach this goal, observation of three-dimensional galvanotaxis must be achieved. Our group has proposed the technique for autofocusing cells by using the diffraction pattern that appears, which we call DepthFrom-Diffraction method. In this paper, we propose a novel three-d...
متن کاملObservation and Prediction of Three-Dimensional
8 Three-dimensional beach features such as crescentic sandbars and rip channels influence beach 9 response to, and recovery from, storm waves, as well as significantly affecting the safety and 10 amenity provided by the surf-zone for beach water-users. In this contribution temporal variations in 11 subtidal and intertidal beach three-dimensionality are observed at a high-energy macrotidal beach...
متن کاملThree-Dimensional Localisation using Cricket System
The Cricket system is a kind of wireless sensor networks used for indoor localisation, which is developed by MIT and Crossbow. It can be deployed to compute the location information for various devices, such as computer and cell phone. This report firstly describes the initialisation of Cricket and the additional resources. Then, a threedimensional localisation algorithm is designed based on th...
