3D and holographic imaging is slowly expanding towards consumer devices such as smartphones. Much of this ‘generalization’ of 3D imaging can be attributed to development of lasers.
R&D in lasers is contributing to the creation of laser based technologies revolutionizing the graphics ecosystem. For instance, photo acoustic tomography is now an established field which makes it possible for scientists to view structures within the human cells with more clarity. In this case, a pulsed laser beam or ionic lasers are used to irradiate the cells. The impulses produced by the cells are captured and provide sharper images. This 3D imaging has improved how confocal laser microscopy is being used.
Relevant applications
On an appropriate scale, argon lasers are a defined improvement in imaging. These lasers are routinely used in analytical techniques like Raman Spectroscopy. So, this has a dual functionality.
On one level, its application is evident on the analytical front (even diagnostics). On the other, its high beam quality makes it relevant for use in imaging. This type of laser is classified as gas/ion lasers and produces large amount of optical power in a green or blue output beam, optimal for use in topography.
In case of medical technology, lasers that use argon are ideal for people suffering from retinal disorders. Diabetic patients suffer from co-morbidities such as weakness of eyesight, which can be rectified using laser argon technology.
3D image synthesis technology
As far as reaching out from the domain of the lab to the wide scale market is concerned, Fujitsu has made great progress. The company recently unveiled a 3D image synthesis technology. This is a perfect application of wide angle lasers, and while Fujitsu is promoting it for vehicular use, its applications are much more than that.
The technology is also going to be used in driver assistance systems. It’ll remove the error of distorted images in the current systems. This would help the driver to accurately view the distances of objects in proximity and prevent collisions.
A key point to note here is that this technology has optimized 3D virtual projection. It can be shifted to other areas such as smartphones and allow users to build digital wireframes and manipulate imagery. It can also be merged with existing augmented reality systems such as Google Glass, and improve the kind of digital projection that they have.
Expanding the range
Another major breakthrough has been increasing the distance from which 3D imaging can be done. The initiative was taken by a group of scientists who have finalized the technology that allows them to produce 3D images of objects that are one kilometer away.
This is a landmark achievement, and would have wide spread applications ranging from navigation use to improvement in educational experiments. The technology provides an improvement which is known as ‘time of flight laser measurement’ ans has existing application in robot vehicles.
The overview that has been provided above gives an up to date analysis on how laser is improving the practical use of 3D imaging technology. The areas where it can be used are immensely diverse. It also provides technology users to innovate and apply concepts such as 3D imaging in domains where it has been used thoroughly – like circuit systems or interactive apps for smartphones.
