My Researcher PLE





Social networks that we can use to investigate:

Some of the most important for researchers are Orcid, Research Gate, Google Scholar, Linkedin, Academia Edu, Hootsuite academy or even Twitter or Facebook.

Use of social networks within the field of knowledge
A good use of them would be to obtain certain information about our area of knowledge, to meet other researchers with whom to interact, and one more means of disseminating the research work carried out.

Opinion of social networks for the researcher 2.0:
Today we use the internet for everything and why not to spread our work and our research. After all, the more people our work reaches, the better. For this reason, it is important to know how to choose which social networks to use for this purpose, to make good use of them and to know them well.
But as always, in social networks, the information we receive must be contrasted and submitted to judgment, and the good thing is that the information that we publish should also be subject to this judgment, which ensures that our work will be reviewed, here another advantage of social networks in the field of research.

Introduction to Laser Sensors

In industrial processes, many quality controls are carried out, usually visually. These inspection processes are carried out by people who sometimes objectively assess whether the piece in question is "good or bad".

They are generally repetitive processes that are interested in automating and establishing an objective and as stable as possible way to assess the quality of the manufactured part.

There are many applicable technologies for the automation of visual quality controls, from 2D cameras, linear cameras, etc. But, many times, the interesting thing is to know and measure the depths of the defects or deviations. For this, a 3D technology is necessary, such as laser profilometry.

"The laser profilometry method is based on the processing of images of laser beams bent by the tested object profile. The figure depicts the simplest way to measure profile height. A narrow laser beam (1) passes through the diffraction module (2) and is converted into laser plane (3). The section of laser plane and tested object surface (5) is the tested object profile recorded by the camera (6). The profile image (7) made on the photosensitive matrix (8) is sent to the signal processor (4) where it is processed and the absolute millimeter dimensions of the object are calculated."

The applications are endless in the nuclear and social field. It can be used for quality control in prismatic extrusion parts, in flat lamination parts to measure their flatness, quality control of welding seams, rails for trains, etc. And in the social field, to control the state of the roads, reconstruction of sculptures, monuments (for example Notre Damme), etc.
