Journal ArticleDOI
COMPU-EYE: a high resolution computational compound eye
TL;DR: This paper proposes COMPUtational compound EYE (COMPU-EYE), a new design that increases acceptance angles and uses a modern digital signal processing (DSP) technique that provides at least a four-fold improvement in resolution.
Journal ArticleDOI
A novel method for controlled synthesis of nanosized hematite (α-Fe 2 O 3 ) thin film on liquid–vapor interface
Pawan Kumar,Raj K. Singh,Nitin Rawat,Partha Bir Barman,S. C. Katyal,Hwanchol Jang,Heung-No Lee,Rajesh Kumar,Rajesh Kumar +8 more
TL;DR: In this article, the surface morphology/size of the nanoparticles constituting the film is tuned in a controlled manner, and the prepared α-Fe2O3 films are crystalline in nature and exhibit superparamagnetic behavior at room temperature.
Journal ArticleDOI
Speckle suppression via sparse representation for wide-field imaging through turbid media
TL;DR: This is the first study to show the benefit of using the SR as compared to the phase conjugation (PC) a de facto standard method to date for TM-based imaging through turbid media including a live cell through tissue slice.
Journal ArticleDOI
Holistic random encoding for imaging through multimode fibers.
TL;DR: In this article, a holistic random (HR) encoding of turbid media was proposed to improve the SNR of image reconstruction in imaging through multimodal fiber (MMF) networks.
Journal ArticleDOI
Enhancing the numerical aperture of lenses using ZnO nanostructure-based turbid media
Richa Khokhra,Manoj Kumar,Nitin Rawat,Partha Bir Barman,Hwanchol Jang,Rajesh Kumar,Rajesh Kumar,Heung-No Lee +7 more
TL;DR: In this article, a morphology-dependent comparative study of the transmittance of ZnO turbid films was conducted, and the results showed that a maximum numerical aperture of around 1.971 of the objective lens with a turbid film of nanosheets was achieved.
