Signal to noise ratio (SNR) is a parameter commonly used to characterize the quality of a measurement and determine the ultimate performance of a system. Given that an incoming ray with incident photon flux. P. given by 200 10 photons pixel second is detected by a photodetector with quantum efficiency. Q. 40%. The system read noise. n. is given by 300 electrons rms pixel. whereas dark noise, D=1.000 electrons/pixel second (1) Determine the SNR value if the integration time, r. of the detector is given by 10 milliseconds (8 marks) (1) Evaluate the system dark noise. D value that is required to produce SVR value of 70 dB with integration time of 50 milliseconds.
