    Abstract: A simple yet versatile noncontact optical inspection instrument and method for inspection of magnetic disk surfaces for surface defects. The instrument is also capable of discriminating between surface defects and surface contaminants. The instrument is comprised of two identical optical sensors (12) which are located on opposite sides of the disk (16). A carriage (14) supports and translates these sensors (12) along the disk radius while a spindle rotates the disk (16). Both surfaces of the disk (16) are therefore simultaneously scanned in a spiral fashion. The sensor's illumination optics produce a monochromatic focused spot of light which is normally incident upon the disk surface. The sensor uses two collection optics channels which simultaneously detect both the specular reflected light and the diffuse scattered light produced by the disk (16) surface. Both the angle and power of the specular reflected light are measured, while just the power of the diffuse scattered light is measured.

    Abstract: A light beam (16) such as a laser beam is used to scan the surface of an egg for flaws such as pin holes, cracks, thinned shell regions, etc. The light beam is vibrated with a rocking/rotating movement to describe a closed curve (52) such as a circle, ellipse or an ellipse so narrow that it is effectively a straight line. The utilisation of such a light beam allows identification of types of flaws due to the character of the progression of light emanating from the egg. The invention includes apparatus for rotating the egg about its longitudinal axis in the path of the beam or beams. The apparatus also includes means for forming the vibrating beam such as mirrors (18) vibrated by out of phase electro-magnetic vibration, piezoelectric actuators (20) or other means.

    Abstract: A cylindrical mirror or lens (12) is used to focus an input collimated beam of light onto a line (20) on the surface to be inspected, where the line is substantially in the plane of incidence of the focused beam. An image of the beam is projected onto an array of CCD (32) parallel to the line for detecting anomalies and/or features of the surface, where the array is outside the plane of incidence of the focused beam. For inspecting surface with a pattern thereon, the light from the surface is first passed through a spatial filter (106) before it is imaged onto the CCD. The spatial filter may be replaced by reflective strips that selectively reflects scattered radiation to the detector, where the reflective strips also shift in synchronism with the relative motion.

    Abstract: A cylindrical mirror or lens is used to focus an input collimated beam of light onto a line on the surface to be inspected, where the line is substantially in the plane of incidence of the focused beam. An image of the beam is projected onto an array of charge-coupled devices parallel to the line for detecting anomalies and/or features of the surface, where the array is outside the plane of incidence of the focused beam. For inspecting surface with a pattern thereon, the light from the surface is first passed through a spatial filter before it is imaged onto the charge-coupled devices. The spatial filter includes stripes of scattering regions that shift in synchronism with relative motion between the beam and the surface to block Fourier components from the pattern. The spatial filter may be replaced by reflective strips that selectively reflects scattered radiation to the detector, where the reflective strips also shifts in synchronism with the relative motion.
