Alexander Murray and Richard Morse invented and patented the first analog color scanner at Eastman Kodak in 1937. Intended for color separation at printing presses, their machine was an analog drum scanner that imaged a color transparency mounted in the drum, with a light source placed underneath the film, and three photocells with red, green, and blue color filters reading each spot on the ...
Many MFP types, regardless of the category they fall into, also come in a "printer only" variety, which is the same model without the scanner unit included. This can even occur with devices where the scanner unit physically appears highly integrated into the product. As of 2013, almost all printer manufacturers offer multifunction printers ...
Dust and scratches on the film can be a big problem for scanning. Because of their reduced size (compared to prints), the scanners are capable of resolutions much higher than a regular flatbed scanner; typically at least 2000 samples per inch (spi), up to 4000 spi or more. At these resolutions dust and scratches take on gigantic proportions.
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.

In object-oriented (OO) and functional programming, an immutable object (unchangeable [1] object) is an object whose state cannot be modified after it is created. [2] This is in contrast to a mutable object (changeable object), which can be modified after it is created. [3]
Using the daguerreotype process, John Benjamin Dancer was one of the first to produce microphotographs, in 1839. [1] He achieved a reduction ratio of 160:1. Dancer refined his reduction procedures with Frederick Scott Archer's wet collodion process, developed in 1850–51, but he dismissed his decades-long work on microphotographs as a personal hobby and did not document his procedures.
