: To make the comb absolute, researchers use a technique called "self-referencing," which involves doubling the lowest frequencies of the comb and comparing them to the highest ones (an "octave") to lock Key Applications
: Used to calibrate spectrographs on telescopes to detect tiny wobbles in distant stars, helping find Earth-like exoplanets .
In a spectrum, these individual frequency lines look like the . Because the distance between these "teeth" is known and perfectly uniform, scientists can use them to measure an unknown frequency by comparing it to the nearest "tooth" on the comb. How It Works optical frequency comb
: They act as "gears" that take the incredibly fast ticks of optical atoms and divide them down to manageable microwave frequencies used in electronics.
: Most combs are created using mode-locked lasers that produce a train of ultra-short pulses at regular intervals. The Comb Equation : Every individual frequency in the comb ( νnnu sub n ) is defined by just two parameters: : To make the comb absolute, researchers use
An is a specialized laser that acts as an "optical ruler," measuring different frequencies (colors) of light with extraordinary precision. Unlike a standard laser that emits one single color, a frequency comb emits hundreds of thousands or even millions of precisely spaced, discrete frequency lines simultaneously. Core Concept: The "Optical Ruler"
Frequency combs are considered Nobel Prize-winning technology (2005) because they revolutionized several fields: How It Works : They act as "gears"
: Modern miniaturized versions small enough to fit on a microchip, opening doors for use in smartphones or portable medical devices.
Add Sense for Chrome works in both the build-in Sense client and in mashups using the Capabilities APIs
Charts displayed with the API through getObject and visualization.show will be tagged.
Used app(s) will be displayed in the bottom right corner.
Properties and other buttons will work just as in the client.
If your mashup shows charts from more than one app, all will be listed.
For all charts, sheets and the app you can click on the cogwheel.
That will display the properties for the object.
Use this to troubleshoot or to investigate what settings produce this chart.
You can display several objects properties at the same time, to make comparisons.
Properties can also be copied to clipboard.
From the app box you can inspect the script, variables and app properties.
Windows can be open at the same time and moved.
You can also copy window contents, complete or partly, to the clipboard.
If you do not have access to the script the script button will not be available.
You can also easily see what extensions and charts are used in your app.
Just click on the extensions button in the app info box.
You will get a list of all axtensions and built-in charts are used in your extension, with title and sheet title
Master objects are also included.
The extension can also help you find performance problems.
When you enable the extension on a page, whether it's the standard client or a mashup, it will start recording recalculation times.
Every time an object is revalidated then extension will register time elapsed for recalculation.
It will also count how many revalidations has occured.
If the object is no longer on the screen, the extension will continue to monitor recalculations, so when you re-enable it you will get all the statistics.
