German engineers have recently developed a new compact imaging system that’s capable of recording hyperspectral images in five dimensions. In other words, the system can capture the data related to multiple wavelengths of light, along with spatial coordinates, as a function of time.
The 5D system represents to the primary lab setup in which high-quality spatial and spectral resolution, depth accuracy, and high framing rate imaging have all been consolidated into a single compact system. It opens up energizing conceivable outcomes for security, restorative imaging — and even shopping for food.
The essential standard of the sensor isn’t at all like the stereo vision that we have as people. Be that as it may, rather than two eyes, which are restricted to the recognition of just noticeable light, the 5D imaging system uses two hyperspectral cameras working in the visible to near-infrared range.
Since the scene is caught from two somewhat unique directions, it’s conceivable to build up the profundity data by distinguishing focuses at first glance that are available in both cameras views. These pictures can be taken as quickly as 17 frames for each second, making this framework quicker than comparative ones.
Stefan Heist, research group leader at Friedrich-Schiller University said, “There is a rapidly growing number of applications, which require the determination of more than just one property of macroscopic measurement objects. Whether in medical imaging, precision agriculture, or optical sorting, for meaningful and reliable results, both the shape of the objects and their spectral properties have to be measured.”
Currently, the system has the size of a laptop, but engineers are hoping to shrink it further.
Heist said, “If the entire sensor can be further miniaturized so that it can eventually be placed in the smartphone, end users at home can [also] benefit from the technology. It could then be used, for example, for the fast inspection of the condition of fruit or vegetables, or for personal medical monitoring.”
The paper demonstrating the camera is published in the journal Optics Express.
