We acknowledge support from the Office of Naval Research under award no. N00014-18-1-2563 and DARPA under the NLM programme, award no. HR001118C0015. Part of the fabrication process was conducted at the Center for Nanophase Materials Sciences, which is a DOE Office of Science User Facility. The remainder of the fabrication process took place in the Vanderbilt Institute of Nanoscale Science and Engineering (VINSE) and we thank the staff, particularly K. Heinrich, for their support.

Image processing has become a critical technology in a variety of science and engineering disciplines. Although most image processing is performed digitally, optical analog processing has the advantages of being low-power and high-speed, but it requires a large volume. Here, we demonstrate flat optics for direct image differentiation, allowing us to significantly shrink the required optical system size. We first demonstrate how the differentiator can be combined with traditional imaging systems such as a commercial optical microscope and camera sensor for edge detection with a numerical aperture up to 0.32. We next demonstrate how the entire processing system can be realized as a monolithic compound flat optic by integrating the differentiator with a metalens. The compound nanophotonic system manifests the advantage of thin form factor as well as the ability to implement complex transfer functions, and could open new opportunities in applications such as biological imaging and computer vision.

I used the free version for six months plus. Using the pro features w/o ads for two weeks at a time, so easily over and over again, gave me the opportunity to realize the benefits of this pro version app. Watching six thirty second or less videos, (sometimes just 8 seconds) every two weeks to lose in-app advertising pop-ups and have full usage of the pro features (3-for adds 3 for features) was really great.Yes I probably could continue to do this forever but for two bucks and to say thanks for giving me a real opportunity to use a great app without being burdened by free version limitations, is well worth it. Thank you! I have never given five stars in an initial review, holding off for coffee, updates, unrealized performance issues compatibilitiesor and other related (over-all) user interface (I think of what tasks can I do with the app, or the obvious benefit of using this app and what is a hinderance to this-what does using this app take away from how I use other apps and device features). I evolve and regress each day causing a ever changing reasoning, which in this case along with the bias of regular personal circumstances resulting in immediate positive results, I see no reason to wait, and no reason they have not earned FIVE stars right now. GOOD JOB AND THANK YOU

Being a person with poor eyesight, I obtained this application from the jump start. Whether it be the micro print on drug bottles, which is what I got it for, to objects hard to see. I also like the fact of being able to take a picture of what I am viewing. I also like it that I can zoom the light manually and automatically as well. Coupled with the mentioned functions, there is a insightful group of visual enhancement functions such as shake reduction. So, you can tell I am a fan and I show it off every chance to others with poor eyesight but cannot afford an appointment with the eye doctor as well as the almost sure prescriptions for lenses that they say cannot be made to fit your frames. I am not saying to not see your eye doctor but what I am saying is the app can postpone that painful purchase of reading glasses and hopefully postpone a full prescription. A real winner.

Y.Z. and J.V. developed the idea. Y.Z. conducted the modelling and theoretical analysis. Y.Z. and H.Z. fabricated the samples with small die size (less than 1 mm2) and H.Z. fabricated the samples based on self-assembled masks. I.I.K. provided the substrates and fabricated the larger die size samples not based on self-assembled masks. Y.Z. performed all of the experimental measurements and data analysis, with assistance from H.Z. Y.Z. and J.V. wrote the manuscript with input from all of the authors. The project was supervised by J.V.

I truly love your App! My eyesight has been declining since I turned 40. I’ve had expensive prescription glasses several times since then and I have either lost them or my prescription wasn’t working properly any longer. So unfortunately since the prescription glasses have been out of my price range for the last couple years. I’ve had to settle for off the rack pharmacy glasses. Which aren’t really that great and in return I’m pretty sure they’ve made my eyesight worse. So anyways to the point. Your MagnifyGlass App has been a real lifesaver for me since it allows me to zoom in and out on all the important fine print on pretty much everything these days. It’s also really great that your App utilizes my cell phones bright light on the opposite side of the screen. I also love that it has the capability to take a picture of whatever I’m looking at and it goes straight into my phone’s photo gallery so I can look back at it for reference if I need to. I’ve told numerous friends and family members and even strangers to download your MagnifyGlass App. Thanks again for providing all of us with your Free App. From: A Big Fan Craig Carter
