class atomiq.components.optoelectronics.photodiode.AnalogPhotodiode(adc_channel, *args, **kwargs)[source]¶

An analog photodiode that gives a voltage proportional to the incidend light power.

Parameters:: adc_channel (ADCChannel) -- The ADC channel that reads the analog voltage of the photodiode

get_power(samples=1, cached=False)[source]¶

Parameters:

Return type:

artiq.language.types.TFloat

_measure(samples=1, cached=False)[source]¶

Parameters:

Return type:

artiq.language.types.TFloat

class atomiq.components.optoelectronics.photodiode.CalibratedPhotodiode(calibration, *args, **kwargs)[source]¶

An analog photodiode with a power calibration

Parameters:

adc_channel -- The ADC channel that reads the analog voltage of the photodiode
calibration (Calibration) -- calibration of the photodiode

_measure(samples=1, cached=False)[source]¶

Get the power incident to the photodiode.

Parameters:

samples (artiq.language.types.TInt32) -- number of samples to take and average before returning the result (default 1)
cached (artiq.language.types.TBool) -- If true, the result of the last measurement is returned, otherwise new measurements are taken (default False)

Returns:

Result of the measurement (possibly averaged over several samples)

Return type:

TFloat
