navigate.model.analysis.camera.compute_noise_sigma

navigate.model.analysis.camera.compute_noise_sigma(Fn=1.0, qe=0.82, S=0.0, Ib=0.0, Nr=1.4, M=1.0)

Compute the noise model for an sCMOS camera.

Parameters:
  • Fn (float) – Excess noise factor (unitless)

  • qe (float) – Quantum efficiency (unitless)

  • S (float or np.array) – Signal (photons/pixel/frame)

  • Ib (float or np.array) – Background (photons/pixel/frame)

  • Nr (float) – Readout noise (e- rms)

  • M (float) – EM gain

Returns:

noise – Estimated noise model (electrons)

Return type:

float or np.array
