FLATBED SCANNERS

 

History of Flatbeds:

Flatbed scanners first emerged in the early 1970s, and were

developed by famed inventor Ray Kurzweil ("Raymond Kurzweil"). Kurzweil developed OCR (Optical Character Recognition) technology that functioned alongside the scanner and included a CCD (Charge-Coupled Device) in the scanner for the first time ("Raymond Kurzweil"). The first flatbed scanners were priced at $3000 and above but the costs dropped drastically in the late 1990s and early 2000s with the decreasing cost of production and increase in availability ("Important Facts

About Flatbed Scanners").

 

How it Works:

Flatbed scanners work by using a

fluorescent light to brighten the text or image being scanned

and by providing contrast through the white screen of the

cover, which is behind the image (Pastrick 309). From this

brightened image the light is reflected off a series of

mirrors, pictured to the left. Each mirror is set a specific angles

to control the transmission of light (Pastrick 309). After the

light photons bounce from one mirror to another they pass

through a filter and then hit the CCD (Pastrick 309). 

"The CCD is essentially an array of thousands of light-detecting

cells, each of which produces a voltage level in proportion to the

amount of light it picks up. An analog-to-digital converter then processes these voltages into digital values, whose precision is based on the number of bits per pixel supported by the scanner" (Pastrick 309). 

 

 

Global Materiality:

Currently CCD technology (250-thousand Pixels) cost between $10-30 depending upon the complexity of the device and quality of its components (Ochi et al. 3). However, in 1980 a 120-thousand DPI CCD cost over a thousand dollars (Ochi et al. 3). The reason for such a dramatic decrease in cost is due to the changes and advances made regarding software chips and microtechnology. Because smaller chips were developed this allowed a smaller circuit board area for the CCD, which simultaneously decreased noise and reduced cost through less materials needed (Ochi et al. 4). This is also resultant from the rise of Asian manufacturing companies which were able to produce devices at lower production cost due to the reduced rate of wages. Exploitation of Asian workers occured frequently in the 1980s and 1990s and still continues today. "By the mid-1970s there were about a million workers employed in the offshore electonics assembly industry in Asia, about 90% women" (Ly 181). Therefore not only do these devices illustrate the problems of unfair worker treatment but propose this exploitation through gender bias. As technology advances and interfaces become seamless the gendered aspect is also erased. In thinking about this relationship between culture and technology, "it has been a part of human experience since that first cave painter, but we've had a hard time seeing it until now" (Johnson 2). But how do we hold international corporations responsible for worker's rights? What impact does this have on the resultant culture? Does the gender of the workers influence the types of technology emerging?
