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 per second.
