finesse.detectors.camera.CCD

Overview

class finesse.detectors.camera.CCD(name, node, xlim, ylim, npts, w0_scaled=True)[source]

Bases: CCDCamera, Image

Camera for detecting the full image of the beam in terms of the intensity.

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.

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

CCD.npts

Number of pixels in each axis.
