Shot Noise SNR calculator
Photon-shot-noise-limited SNR from flux, QE and integration time.
Category: Detectors
Formula: SNR = √(η · Φ · t)
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Photon flux Φ | phi | γ/s | 1000000 |
| QE η | qe | 0.7 | |
| Integration t | t | s | 0.01 |
Result with the default inputs
- Detected e⁻: 7000
- Shot-noise SNR: 83.666
Open it with your own values: put each input in the address as a parameter, for example /calculators/shot-noise-snr?phi=1000000. A unit other than the listed one goes in <parameter>_unit.
