Image authentication has applications in security systems, photo forensics, and photo journalism. This paper presents an image authentication scheme using added signal-dependent noise. Imperceptible n...
Study on high signal-to-noise ratio (SNR) silicon p-n junction photodetector
silicon p-n junction photodetector
2011/5/3
On the basis of n-type single-crystal (100) silicon substrate, a silicon p-n junction photodetector has been successfully developed. Three methods to improve photoresponse signal-to-noise ratio (SNR) ...
