Glass chart. A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.
A line-scan camera is a system for producing two-dimensional images using a single sensor element. They normally consist of a rapidly rotating mirror or prism placed in front of the sensor to provide scanning in one direction while the movement of the recording material, often photographic film , provides scanning in the second direction.
Stacks of compact disc jewel cases. Optical disc packaging is the packaging that accompanies CDs, DVDs, and other formats of optical discs.Most packaging is rigid or semi-rigid and designed to protect the media from scratches and other types of exposure damage.
Laser scanning is the controlled deflection of laser beams, visible or invisible. [1] Scanned laser beams are used in some 3-D printers, in rapid prototyping, in machines for material processing, in laser engraving machines, in ophthalmological laser systems for the treatment of presbyopia, in confocal microscopy, in laser printers, in laser shows, in Laser TV, and in barcode scanners.
Data storage is the recording (storing) of information in a storage medium. Handwriting, phonographic recording, magnetic tape, and optical discs are all examples of storage media.
