Research on Light Amplification Panel Based on Stimulated Radiation

Abstract

Light amplification panel (LAP) based on laser principle is put forward in this paper. The LAP is coupled between the camera and eyepiece of the night vision devices to realize image intensification. The quality of imaging in low level light is gained enhancement. After analysis on principle of LAP, its gain, detection capability, imaging performance, noise and bandwidth are calculated theoretically. Laser media arranged alternately amplifies signals of different wavelength, broadening the bandwidth and also realizing night vision color imaging by physical mode.

Analysis and improvement of SNR in FBG sensing system

“…The SNR of the system becomes higher when the insertion loss of the signal reduces and the return loss of the optical devices increases. An optical device with good quality works with low insertion loss and high return to provide a high SNR [14][15][16].…”
