A system for inspecting a slab of material may include an optical fiber, a broadband light source configured to emit light having wavelengths of 780-1800 nanometers over the optical fiber, a beam-forming assembly configured to receive the light over the optical fiber and direct the light toward a slab of material, the beam-forming assembly may be configured to maintain the position of one or more elements within the beam-forming assembly despite changes in environmental temperature; a computer-controlled etalon filter configured to receive the light over the optical fiber, filter the light, and direct the light over the optical fiber; and a computer-controlled spectrometer configured to receive the light over the optical fiber after the light has been filtered by the etalon filter and after the light has been reflected from or transmitted through the slab of material and spectrally analyze the light.

It is therefore an objective to provide an object multi-perspective inspection apparatus and a method therefor. The apparatus includes an image capture device; an inspection site and at least two reflection devices, being arranged for reflecting simultaneously to the image capture device at least two different side views of the object located in the inspection site; wherein: the image capture device has a field of view including the at least two different side views of the reflection. By introducing reflection devices into the inspection apparatus to enable the image capture device to see the part from multiple views at once, multiple surfaces can be inspected at once, in one image frame, without having the need to reposition the reflection device, the camera and/or the object for every single surface. There are more than one reflection devices placed in the camera's field of view to assist the inspection process by exploiting otherwise hidden surfaces of any given solid object. The effort inspecting every single part form multiple sides is reduced. Therefore, the period of the inspection cycle time can be reduced and inspection on the level of multi-surfaces becomes possible increasing overall quality.

A glass inspection equipment includes a first transfer rail extending in a first direction, where a glass including first sides and second sides extending in a direction intersecting the first sides reciprocates in the first direction, a rotation part on the first transfer rail to rotate the glass, an edge inspection part on the first transfer rail to inspect the first and second sides of the glass, and a surface inspection part which inspects a surface of the glass, the edge inspection part inspects the first sides when the glass with the first sides arranged parallel to the first direction is transferred under the edge inspection part, and the edge inspection part inspects the second sides when the glass transferred through the edge inspection part is rotated by the rotation part and the glass with the second sides parallel to the first direction is transferred under the edge inspection part.

A device for inspecting a foil-type transparent object. The device has a camera and at least one light source. The light source is arranged such that the electromagnetic radiation emitted by the light source illuminates a line-shaped area of a first surface of the object from above or a second surface of the object from below. The illumination is at a predetermined angle (?) to the respective illuminated surface. The camera is arranged to detect the intensity of the back-reflected electromagnetic radiation in at least a portion of the line-shaped area. The predetermined angle (?) is less than or equal to 15? and the electromagnetic radiation emitted by the light source (20) is predominantly linear and s-polarized. Also a method of inspection.

A device to detect and analyze defects in magnified scale images of a surface of a finished product illuminated with a blue light source and viewed by multiple image-capturing devices each focused on their own spot includes a supporting mechanism, a transmitting mechanism, a detecting mechanism, and a processor. The transmitting mechanism carries and transmits the product. The detecting mechanism includes a detecting frame, a blue light source assembly. The processor is used to connect to a camera assembly, and preprocess the image of the front of the product to obtain a detection and analysis of any defects of the front of the product.

Methods, systems, and apparatus for detection of a condition in a hole defined by a transparent material that is at least partially enclosed by one or more substantially opaque materials. The method may include positioning a light source in a first hole in the transparent material, directing light from the positioned light source through the transparent material and toward a second hole that is adjacent to the first hole. A prism may be positioned so that the light transmitted from the light source through the machined inner surface of the second hole is visible through a viewing face of the prism. By observing the transmitted light, a surface condition of the machined inner surface of the second hole may be determined.
