fouriax.Sensor

class Sensor

Bases: ABC

Base interface for converting optical fields into detector measurements.

Subclasses implement measure(), which maps a Field or Intensity to a real-valued measurement array. An optional key argument supports stochastic sensor noise models.

__init__()

Methods

__init__()
measure(field, *[, key])	Produce a measurement from field.
validate_for(field)	Check that field is compatible with this sensor.

abstractmethod measure(field, *, key=None)

Produce a measurement from field.

Parameters:

• field (Field | Intensity) – Input optical field or spatial intensity.

• key (Array | None) – Optional JAX PRNG key for stochastic noise sampling.

Returns:

Measurement array derived from field. Concrete sensors define the exact shape and reduction over wavelength or polarization axes.

Return type:

Array

validate_for(field)

Check that field is compatible with this sensor.

Parameters:

field (Field | Intensity)

Return type:

None
