Scanners equipped with charge-coupled device (CCD) scanning elements require a sophisticated series of mirrors and lenses to reproduce an image, but the result of this complexity is a much higher-quality scan. Because CCDs have a much greater depth of field, they are more forgiving when it comes to scanning documents that are difficult to get ...
Laser barcode scanners utilize a semiconductor laser diode to produce a laser beam. This beam is directed by a deflection mirror onto a polygon mirror wheel. The design may include a focusing device, enabling the scanner to adjust the beam to scan at various distances. [2] The scanner deflects the laser beam using a rotating mirror wheel.
Video of the process of scanning and real-time optical character recognition (OCR) with a portable scanner. Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene photo (for example the text on signs and ...
The device then looks at the contrasting reflectivity of the light at certain positions on the form. It will detect the black marks because they reflect less light than the blank areas on the form. Some OMR devices use forms that are printed on transoptic paper. The device can then measure the amount of light that passes through the paper.

A scanning radio will sequentially monitor multiple programmed channels, or scan between user defined frequency limits and user defined frequency steps. The scanner will stop on an active frequency strong enough to break the radio's squelch setting and resume scanning other frequencies when that activity ceases. [citation needed]
Medical imaging equipment is manufactured using technology from the semiconductor industry, including CMOS integrated circuit chips, power semiconductor devices, sensors such as image sensors (particularly CMOS sensors) and biosensors, and processors such as microcontrollers, microprocessors, digital signal processors, media processors and ...
There are four types of fingerprint scanners: [7] optical scanners, capacitance scanners, ultrasonic scanners, and thermal scanners.The basic function of every type of scanner is to obtain an image of a person's fingerprint and find a match for it in its database.
