Fiber Optic Gyroscope Overview

[@epsisphal]

Great explanation on why there is a phase modulator in fibre optic gyros. Thank you!

[@ianofSST]

Appreciate the effort that went into this! Very easy to understand, and just what I was looking for

[@geor664]

Loved the maths explanation. Elegant

I was just looking for this content, I have selected this topic as my final project for my photonic course. I was not sure if I should go for this or chooses something else, but after watching it, I m definitely gonna do it. Thank you for this video.....

y is cross-track error, often given in units of nautical miles.

Hi Marco, It really depends on a lot of factors. You can get cheap gyros for you’re yacht, but I’m sure the ones they use in spacecraft are much more expensive.

this is good stuff!!!

[@iloveprivacy8167]

If I'm understanding this right, the phase modulators (3:55) are effectively acting as a magnifying glass, multiplying the spread between the light paths, thus increasing the phase shift, so it's easier to detect? Thanks in advance to anyone who can confirm/clarify!

Thank you so much @Jonathan, I wanted to know why does a phase shift occur when rotation occurs ? Please please reply ! I need to know the answer, Internet is not helping much. :(

Really great video 10/10

Is the Sagnac Interferometer and FOG the same?

[@eleanorscholefield3863]

Hey, bit confused on the bias error equation. Where did you get the trajectory error from? And what are the units for it?

[@marcodias2419]

how much these fiber optic gyros cost? I have a load of them by IAI / TAMAM FOG1

#wonderful video! Very simple explained ! #thx!

[@connorcox4006]

Nice video!

[@mjobrien69]

The lego brick diagram was good! You can leave out all the maths :D

[@jaconbob]

Nice video... But looks like you are trying to hard to show off with your looked up math stuff.

[@-danR]

Looks like he's trying hard to present a _complete_ formal rationale for actual interference computations.

[@geor664]

The maths explanation helps back up his arguments. If you dig deeper into inertial navigation systems, the maths presented here is a tiny fraction of what is used. He's giving you a clue that there is a whole lot more available.
