pysted.base.Detector

class pysted.base.Detector(**kwargs)

This class implements the photon detector component.

Parameters:

parameters – One or more parameters as described in the following table, optional.

Parameter	Default	Details
n_airy	0.7	The number of airy disks used to compute the pinhole radius \(r_b = n_{airy} 0.61 \lambda/NA\).
noise	True	Whether to add poisson noise to the signal (boolean).
background	0	The average number of photon counts per second due to the background [1].
darkcount	0	The average number of photon counts per second due to dark counts.
pcef	0.1	The photon collection efficiency factor is the ratio of emitted photons that could be detected (ratio).
pdef	0.5 [2]	The photon detection efficiency factor is the ratio of collected photons that are perceived by the detector (ratio).
det_delay	750e-12	Delay between the beginning of a period the start of the detection
det_width	8e-9	Detection duration

[1]

The actual number is sampled from a poisson distribution with given mean.

Detector.get_detection_psf(lambda_, psf, na, ...)	Compute the detection PSF as a convolution between the fluorscence PSF and a pinhole, as described by the equation from [Willig2006].
Detector.get_signal(photons, dwelltime, rate)	Compute the detected signal (in photons) given the number of emitted photons and the time spent by the detector.
