ChromaticAberrationChart

Chart displaying chromatic aberration of optical system

Since R2026a

Description

Add-On Required: This feature requires the Optical Design and Simulation Library for Image Processing Toolbox add-on.

A ChromaticAberrationChart object stores information used to display the lateral and longitudinal chromatic aberration of an optical system. You can change aspects of the display, such as the title, line color, and legend, by modifying properties of the ChromaticAberrationChart object.

Creation

Create a ChromaticAberrationChart object by using the show function with a ChromaticAberration object.

Properties

ChromaticAberration — Chromatic aberration results

ChromaticAberration object

Chromatic aberration results, specified as a ChromaticAberration object.

Color — Line color

RGB triplet | hexadecimal color code | color name | M-by-3 numeric matrix | M-element string vector | ...

Line color, specified as an RGB triplet, a hexadecimal color code, or a color name. You can also specify multiple colors as an M-by-3 numeric matrix where each row is an RGB triplet, or as an M-element string vector where each element is a hexadecimal color code or color name. If you specify a single color, the chart displays all results using the same color. If you specify multiple colors, then M must be equal to the number of wavelengths.

For a custom color, specify an RGB triplet or a hexadecimal color code.

• An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range [0,1], for example, [0.4 0.6 0.7].

• A hexadecimal color code is a string scalar or character vector that starts with a hash symbol (#) followed by three or six hexadecimal digits, which can range from 0 to F. The values are not case sensitive. Therefore, the color codes "#FF8800", "#ff8800", "#F80", and "#f80" are equivalent.

Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and the hexadecimal color codes.

Color Name	Short Name	RGB Triplet	Hexadecimal Color Code	Appearance
"red"	"r"	[1 0 0]	"#FF0000"
"green"	"g"	[0 1 0]	"#00FF00"
"blue"	"b"	[0 0 1]	"#0000FF"
"cyan"	"c"	[0 1 1]	"#00FFFF"
"magenta"	"m"	[1 0 1]	"#FF00FF"
"yellow"	"y"	[1 1 0]	"#FFFF00"
"black"	"k"	[0 0 0]	"#000000"
"white"	"w"	[1 1 1]	"#FFFFFF"

Example: Color="r"

Example: Color="green"

Example: Color=[0 0.4470 0.7410]

Title — Chart title

"Chromatic Aberration" (default) | string scalar | character vector

Chart title, specified as a string scalar or character vector.

Data Types: char | string

Legend — Legend display

"on" (default) | "off" | true or 1 | false or 0

Legend display, specified as "on" or "off", or as numeric or logical 1 (true) or 0 (false). A value of "on" is equivalent to true, and "off" is equivalent to false. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

Grid — Grid lines to display

"off" (default) | "major" | "minor"

Grid lines to display, specified as one of these options.

• "major" — The chart displays only major grid lines.

• "minor" — The chart displays major and minor grid lines.

• "off" — The chart does not display any grid lines.

Data Types: char | string

Parent — Parent UI container

Figure object | Panel object | Tab object | TiledChartLayout object

Parent UI container, specified as a Figure object, Panel object, Tab object, or TiledChartLayout object. By default, the function creates a new Figure object. You can create these UI containers using their respective creation functions.

• UI Figure — uifigure

• UI Panel — uipanel

• UI Tab — uitab

• UI Tiled Layout — tiledlayout

Examples

Compute Chromatic Aberration of Double Gauss Lens

Create an optical system that contains a double Gauss lens using the createDoubleGauss helper function. The function is attached to this example as a supporting file.

opsys = createDoubleGauss;

Trace the marginal rays and the chief ray for the optical system.

mrays = traceMarginalRays(opsys);
cray = traceChiefRay(opsys);

Display a 2-D visualization of the optical system and the traced rays. The displayed chief ray is red, and the marginal rays are blue.

hv = view2d(opsys);
addRays(hv,mrays,Color="b")
addRays(hv,cray,Color="r")

Compute the chromatic aberration of an optical system using the chromaticAberration object function. Specify the maximum field angle as 15 degrees using the MaxFieldAngle name-value argument. Display the results using the show object function.

ca = chromaticAberration(opsys,Wavelengths=[486 586 656],MaxFieldAngle=15);
show(ca)

ans = 
  ChromaticAberrationChart with properties:

    ChromaticAberration: [1×1 optics.result.ChromaticAberration]
                  Color: [3×3 double]
                  Title: "Chromatic Aberration"
                 Legend: on
                   Grid: "off"
                 Parent: [1×1 Figure]
