JanesickDepletionModel#

class optika.sensors.materials.depletion.JanesickDepletionModel(thickness, thickness_substrate, chemical_substrate, width_pixel, mcc_measured=None)[source]#

Bases: AbstractDepletionModel

A depletion model that relies on Janesick [2001]’s model of charge diffusion to measure the thickness of the field-free region of an imaging sensor and infer the thickness of the depletion region.

Attributes

`chemical_substrate`	A model of the optical properties of the substrate material.
`mcc_measured`	An optional measurement of the mean charge capture that can be used to compute residuals.
`shape`	The array shape of this object.
`thickness`	The thickness of the depletion region of this sensor.
`thickness_substrate`	The thickness of the light-sensitive region of this sensor.
`width_pixel`	The physical size of a pixel on this sensor.

Methods

`__init__`(thickness, thickness_substrate, ...)
`fit_mcc`(thickness_substrate, ...[, mcc_measured])	Given a measured mean charge capture, find the thickness of the depletion region which best matches the measurements.
`mean_charge_capture`(wavelength)	The mean charge capture of this sensor for the given wavelength computed using `optika.sensors.mean_charge_capture()`
`to_string`([prefix])	Public-facing version of the `__repr__` method that allows for defining a prefix string, which can be used to calculate how much whitespace to add to the beginning of each line of the result.

classmethod fit_mcc(thickness_substrate, chemical_substrate, width_pixel, mcc_measured=None)[source]#

Given a measured mean charge capture, find the thickness of the depletion region which best matches the measurements.

Parameters:

thickness_substrate (Quantity | AbstractScalar) – The thickness of the light-sensitive region of this sensor.
chemical_substrate (AbstractChemical) – A model of the optical properties of the substrate material.
width_pixel (Quantity | AbstractScalar) – The physical size of a pixel on this sensor.
mcc_measured (None | FunctionArray) – The measured mean charge capture that will be fit by the function optika.sensors.mean_charge_capture().

mean_charge_capture(wavelength)[source]#

The mean charge capture of this sensor for the given wavelength computed using optika.sensors.mean_charge_capture()

Parameters:: wavelength (Quantity | AbstractScalar) – The wavelengths at which to evaluate the mean charge capture.
Return type:: AbstractScalar

to_string(prefix=None)#

Public-facing version of the __repr__ method that allows for defining a prefix string, which can be used to calculate how much whitespace to add to the beginning of each line of the result.

Parameters:: prefix (None | str) – an optional string, the length of which is used to calculate how much whitespace to add to the result.
Return type:: str
