Like sonar or radar terahertz imaging produces an image by comparing measurements across an array of sensors.
since the distance between sensors is proportional to wavelength. In the latest issue of IEEE Transactions on Antennas and Propagation researchers in MIT s Research Laboratory for Electronics describe a new technique that could reduce the number of sensors required for terahertz
or millimeter-wave imaging by a factor of 10 or even 100 making them more practical.
so that light reflected by a small patch of the visual scene strikes a correspondingly small patch of the sensor array.
In lower-frequency imaging systems by contrast an incoming wave whether electromagnetic or in the case of sonar acoustic strikes all of the sensors in the array.
and intensity of the wave by comparing its phase the alignment of its troughs and crests when it arrives at each of the sensors.
As long as the distance between sensors is no more than half the wavelength of the incoming wave that calculation is fairly straightforward a matter of inverting the sensors measurements.
But if the sensors are spaced farther than half a wavelength apart the inversion will yield more than one possible solution.
Those solutions will be spaced at regular angles around the sensor array a phenomenon known as spatial aliasing.
however any given circumference around the detector is populated usually sparsely. That s the phenomenon that the new system exploits.
Keeping every tenth sensor won t work: It s the regularity of the distances between sensors that leads to aliasing.
Arbitrarily varying the distances between sensors would solve that problem but it would also make inverting the sensors measurements calculating the wave s source and intensity prohibitively complicated.
Regular irregularityso Wornell and his co-authors James Krieger a former student of Wornell s who is now at MIT s Lincoln Laboratory
and Yuval Kochman a former postdoc who is now an assistant professor at the Hebrew University of Jerusalem
instead prescribe a detector along which the sensors are distributed in pairs. The regular spacing between pairs of sensors ensures that the scene reconstruction can be calculated efficiently but the distance from each sensor to the next remains irregular.
The researchers also developed an algorithm that determines the optimal pattern for the sensors distribution.
In essence the algorithm maximizes the number of different distances between arbitrary pairs of sensors. With his new colleagues at Lincoln Lab Krieger has performed experiments at radar frequencies using a one-dimensional array of sensors deployed in a parking lot
which verified the predictions of the theory. Moreover Wornell s description of the sparsity assumptions of the theory 10 percent occupation at a given distance means one-tenth the sensors applies to one-dimensional arrays.
Many applications such as submarines sonar systems instead use two-dimensional arrays and in that case the savings compound:
One-tenth the sensors in each of two dimensions translates to one-hundredth the sensors in the complete array.
James Preisig a researcher at the Woods hole oceanographic institution and principal at JP Analytics says that he s most interested in the new technique s ability to reduce the computational burden of high-resolution sonar imaging.

Using this kind of sensor doctors may be able to better determine radiation doses and to monitor whether treatments are having the desired effect according to the researchers who describe the device in the Proceedings of the National Academy of Sciences the week of April 21.
This is the first MRI sensor of any kind that can be left in the body for extended periods of time so far up to four weeks in testing with rats.
With the new MIT sensor doctors could track the state of the tumor and predict how it might respond to radiation treatment according to the researchers.
The new MRI sensor combines two forms of silicone a solid called PDMS and a substance known as DDMPS which has an oily consistency.
The researchers shaped this polymer into a 1. 5-millimeter sensor that could be implanted in tissue during a biopsy;
After injection these particles clump together to form a solid sensor. DDMPS absorbs molecular oxygen
To test the sensors the researchers implanted them in the hind legs of rats and then measured how the signal changed as the rats breathed pure oxygen regular air and pure oxygen again.
The sensors detected changes in oxygen pressure as small as 15 millimeters of mercury and it took less than 10 minutes to see the effects of a change in inhaled gas.
When the experiment was repeated four weeks later the sensors yielded the same results.
