In early tests, this laser-activated silk and gold material held wounds together better than stitches or glue.

This paper presents an experimental evaluation of different line extraction algorithms on 2D laser scans for indoor environment. Six popular algorithms in mobile robotics and computer vision are selected and tested. Experiments are performed on 100 real data scans collected in an office environment with a map size of 80m × 50m. Several comparison criteria are proposed and discussed to highlight the advantages and drawbacks of each algorithm, including speed, complexity, correctness and precision. The results of the algorithms are compared with the ground truth using standard statistical methods.

There are a number of parameters measured by the ILDA Test Pattern. The most critical one for speed-related issues is a circle that is drawn outside a square. As the scanner speed is turned up, the scanner can’t accurately track the circle, so the circle gets smaller. When the circle is just touching the center of the square’s sides, this indicates the circle’s tuning.

I think everybody saw Laser Effects that shows up stages, discos or festivals. There are two categories on the laser effect. One is Beam Effect, it shows the laser beams that flying in the air to the audience. The other is Screen Effect, it shows the laser graphics that drawn on the screen by a moving laser spot. The first one is preferred better than second. The beam effect is very exciting, so that many Laser Light Shows are also being given. The laser equipments working in the laser light show are called Laser Projector.
