- Instrument Introduction
Computer-based 3D measurement and imaging technology is a key application within the field of information technology. The Moire contour method, also known as the Moire contour line method, is a non-contact method for measuring the surface topography of three-dimensional objects. By projecting three-dimensional contour lines, the external shape characteristics of an object can be measured. This experimental system utilizes a projection-type Moire contour measurement system to project the image of a reference grating onto the surface of the object under test via an optical system, forming a distorted grating modulated by the surface elevation of the object.
- Product Features
· A CCD captures the image of the distorted stripes on the object’s surface and transfers it to a computer, where the Moire contour stripes on the object’s surface are automatically processed using the phase-shifting method.
