finesse.detectors.camera.FieldCamera
¶
Overview
- class finesse.detectors.camera.FieldCamera(name, *args, **kwargs)[source]¶
Bases:
ComplexCamera
,Image
Camera for detecting the full image of the beam in terms of amplitude and phase.
Get the unscaled x and y coordinate data via
Image.xdata
andImage.ydata
, respectively.- Parameters
- namestr
Unique name of the camera.
- node
OpticalNode
Node at which to detect.
- xlimsequence or scalar
Limits of the x-dimension of the image. If a single number is given then this will be computed as \(x_{\mathrm{lim}} = [-|x|, +|x|]\).
- ylimsequence or scalar
Limits of the y-dimension of the image. If a single number is given then this will be computed as \(y_{\mathrm{lim}} = [-|y|, +|y|]\).
- nptsint
Number of points in both axes.
- fscalar, optional; default: 0
Field frequency offset from the carrier to detect.
- w0_scaledbool, optional; default: True
Flag indicating whether the \(x\), \(y\) axes should be scaled to the waist-size of the beam parameter at node.
Properties
Number of pixels in each axis. |
