How it Works
We split light from the imaging lens into two beams with a prism. The beams are sent over different path lengths to two detectors.
We take a series of synchronized images with the two detectors. The images are very short exposures (down to 10s of nanoseconds) at very high frame rates (10’s to 100’s of kHz).
For each frame, we compare the signals from the two detectors to measure the quantum noise. We then combine the noise from all the frames to form a turbulence free image.
Normal Image (top)
The standard image, which measures the average light intensity to hit each pixel, results in a blurred image.
Quantum Image (bottom)
A cross correlation measurement. In this image the the lines are much sharper. The quantum image was formed from 1000 frames with a 2 ms exposure time.
• The camera finds signal in
what is typically perceived to be noise, thus producing high resolution images with the same amount of information currently available to a charge-coupled device (CCD). The camera creates a single image out of two CCD’s.
• One CCD captures the image in the same way as a typical camera. The 2nd CCD measures a Fourier transform of the same field of view. Post processing combines these two data sets or images to output a processed image with a far higher resolution than the optics could have achieved alone.
• The ability to obtain ultra-high resolution images from ground or air level angles where proximity to the target is either unsafe or would disturb the target.
•High quality lenses can be very heavy for military equipment especially drones
• Interchangeable lenses can be very expensive and limits a photographers options.
• Light-weight lenses will be more effective for military vehicles, aircrafts, and drones.
• The high resolution images will create new strategic advantages for military.
• New capabilities will allow for an affordable product while allowing photographers to ensure quality.
