finesse.detectors.camera.FieldCamera

Overview

class finesse.detectors.camera.FieldCamera(name, node, xlim, ylim, npts, f=0, w0_scaled=True)

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 and Image.ydata, respectively.

Parameters:

namestr

Unique name of the camera.

nodeOpticalNode

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

FieldCamera.npts

Number of pixels in each axis.
