Topcon's DRI OCT Triton and Triton Plus models use swept source OCT technology that provides 100,000 A-scans per second, eye tracking and invisible scan lines
to minimise patient distraction when imaging.
The problem was that this wasn't enough bandwidth for the standard video camera of the day that transmitted 525 scan lines
of data at 30 frames per second at 5 MHz.
The former occur when joints are longer than the analysed outcrop and cannot be entirely measured; the latter take place because larger joints are typically characterized by higher spacing values influencing sampling probabilities and, consequently, require very long scan lines
to collect an adequate number of fractures for a statistical sampling.
As shown in Figure 3, the starting points for connecting two scan lines
are [l.sub.k](l) and [l.sub.k+1](1); the end point are [l.sub.k](t) and [l.sub.k+1] (t).
For atomic resolution images, the error due to a fast scan rate appears to be large intensity fluctuations between scan lines
, as shown in Figures 1(c) and 1(d).
However, the sensor line speed has been increased to 100 Hz, producing 2.5 times the number of scan lines
. When combined with the auto-rotation of the sensor head, a marked improvement in the resolution, cleanliness and structure of the resulting point cloud is achieved, said GeoSLAM.
The advantages of an intermedial approach to science fiction cinema appear especially pronounced in Thomas LaMarre's highly original chapter on cyborg perception, "Scan Lines
: How Cyborgs Feel." LaMarre treats this staple of science fiction cinema using the phenomenon of the scan line
: scan lines
, appearing in visual media when different media platforms are brought into proximity, signal an encounter between competing modes of information and transmission, an effect associated by LaMarre with human-technological perception in Mamoru Oshii's The Ghost in the Shell (1995) and the intermedial character of animated science fiction generally.
He even adds filters to simulate the flickering of film and the scan lines
of videotape, turning them on and off throughout, lest we miss the point that this is a collision of forms in which incongruous textures and colors are muddled together.

Parameters besides laser speed can include laser power, distance between laser scan lines
, scanning strategy, and powder layer thickness.
This scan method uses 5 horizontal scan lines
, each 3 mm long, with a 250-pm distance between each line.
The mirror has good imaging performance, operating to 20 scan lines
per second below resonance and above resonance at 200 scan lines
