LASER DETECTOR FOR SURFACE DEFECTS Patent no /2012-Egyptian Patent Office HEBATALRAHMAN AHMED –EGYPT Hebatalrahman11@yahoo.com
**Summary Summary** Summary Device for the detection of surface defects of materials. It is nondestructive method depends mainly on the optical properties of laser beams. The device is in the form of sphere, the laser beams in visible range are distributed on the external surface of the unit. At least one laser entrance in face of each surface of the examined specimen or the selected surface for examination. The inner surface of the device was covered by sensitive films which affected by reflected raysand compare it with standard sample. The examined sample is hinged at the central plane of the sphere center by fixation elements.
*New Topics* Using the optical properties of a laser beam to detect surface defects Laser detection works with plastics and ceramic materials and alloys and depends on the surface properties of the examined body Economic and non destrtuctive way does not affect the product's properties Detection is done on all sides at the same time with the possibility of keeping pictures on the film or digital screen
**Applications** Detection of surface defects in castings Detection surface welding defects Detect surface defects in the manufacturing of plastics Quality control processes (inspection) in factories products Control over the food products and pharmaceutical industries.
