A problem that was also addressed is obtaining a linear scan that is a constant problem of scanners (Li, 1995).
3) and the galvanometer scanner (GS), was studied (Duma, 2008), with an enhanced duty cycle n with regard to the state-of-the-art (Gadhok, 1999) and a linear scan on its active portions.
Here's how it works: The sensor moves in a precise linear scan, and the computer acquires data points at intervals selected by the user.
Intermec EV10 linear scan engine delivers flexibility for reading high density, PDF41, and standard-range codes
The SF51 uses the Intermec EV10 linear scan engine, delivering flexibility by combining high density, PDF417 and standard range bar code reading in one scan engine.
Because the Imager 8000 operates on a digital image rather than a linear scan line, it provides true omni-directional reading capability.
Examples of horizontal linear scans and three-dimensional OCT imaging are both explained and depicted for non-proliferative and proliferative retinopathy with macular oedema.
The measurements were linear scans by a scanning electron microscope (SEM) across a semiconductor chip on which a circuit had been etched.
To test the MIR imaging system, linear scans for each laminate were acquired.
Here, linear recording has a big advantage because the linear scans much easier, allowing parallel data channels compared to helical technology.
Successive linear scans were taken after rotating the object progressively in 5 [degrees] increments through 180 [degrees].
