SimpleFieldSensor

SimpleFieldSensor reports the temporally-integrated complex field of the incident light (see the LightLike User Guide for a discussion of this physical quantity). The complex grid of the Light is first interpolated from the propagation mesh onto the sample mesh specified by nxy & dxy; phase due to tilt and focus in the reference wave of the Light is then added to the sample grid. If multiple lights are received simultaneously they are assumed to be mutually coherent, so their complex fields add. See the LightLike User Guide for detailed discussion of the treatment of interference in LightLike sensors.

See the LightLike User Guide for a detailed discussion of the triggering of sensor exposures. Note in particular that the input "sampleInterval" is only used to generate multiple samples within one "exposureLength". To obtain one sample per "exposureLength" (the typical practice), set "sampleInterval" to 0.0.

Like all LightLike optical sensors, SimpleFieldSensor works with both pulsed and continuous wave illumination. It has a single Light input, representing the incident light.
