RISAnalysis and Modeling of Optical Elements and Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper a new generalized methodology to analyze optical elements and systems is introduced. The reflection and refraction laws are formulated in the form of a homogeneous transformation ...
Applications of D-H Notation in Machining and On-Line Measurement of Roller-Gear Cams on 5-Axis Machine Tools
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A kinematic model is presented to aid in the design of cam-profiles and determine the NC data equations using Denavit-Hartenberg (D-H) notation to produce and to measure the dimension accuracy ...
Modeling and Sensitivity Analysis of Laser Tracking Systems by Skew-Ray Tracing Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser tracking systems, such as the Leica LTD 500, are used for precision position measurement of large or distant objects, for example, the alignment of aircraft wings or bridge girders during ...
Camera Calibration Based on Snell’s Law
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper we present a camera calibration method using Snell’s Law. Traditional camera calibration is based on the pinhole model, which is an approximation algorithm using untrue geometrical ...
Laser Surface Height and Orientation Measurement System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a new optical measurement system that measures the surface height and orientation changes. Homogeneous transformation matrices are used to derive the sensor reading equations. ...
A New Model of Binocular Stereo Coordinate Measurement System Based on Skew Ray Tracing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two-CCD binocular stereo vision systems using pinhole model are attracting research interest in many important fields such as 3-D coordinate measurement. However, new system modeling is difficult ...
A New Method to Analyze Spatial Binary Mechanisms With Spherical Pairs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the most popular mathematical tools in the fields of robotics and mechanisms is the Denavit-Hartenberg (DH) notation ( and , 1955, J. Appl. Mech., 77, pp. 215–221). It is valid only ...
Analysis of Errors in Precision for Closed Loop Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An algorithm to analyze the relations of error components for closed loop mechanisms is introduced. The error components considered are errors in link dimensions and error motions due to joint ...
Dimension Inspection of Spatial Cams by CNC Coordinate Measuring Machines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problem of spatial cam inspection is still predominantly approached from simple gauging by manufacturers in today’s industry, despite the fact that Coordinate Measuring Machines (CMM) is both ...
Skew Ray Tracing and Sensitivity Analysis of Geometrical Optics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to improve upon the inconvenient and complicated contemporary analytic techniques employed for optical systems, this paper investigates two important optical topics: (1) the determination ...
