MPE calculations made easy

[mccarrot]

Hi Guys,

I made a start in implementing the MPE calculator into html (javascript) so its platform independenant (on mobile devices you simply place the html file offline) and 50% is already done and working.

I'm looking for some testers on other platforms like macbook and android. (I only have windows XP and IPAD to test) and can use some feedback to make this tool easy to use.

any volunteers?

Gidday,

I can do both, have a macbook pro and a Android (running shitty old 1.6 tho) but it's a start!

Here is the first screenshot, made on my Ipad
feedback please.



I send the link to one volunteer....

looks good to me.

Looks good to me, now all the issues surround payments have been resolved.

I don't have an iphone but if I did.....

This will be the location where you can find the mpe calculator tool:

There will be more updates in the future.

Can someone post the MPE, Divergence, Irradiance and other equations, i am done with the iOS/andriod framework just need to input the math then i can share with everyone...

[mccarrot]

MPE = 1.8 x 10^-3 x t^3/4 Joules/cm2

Irridance = mW / cm2

[hivelaser]

hi mcarrot can you explain a little what is the 1.8, do you mean 10 to the power of 3 x t what is t please can you write it out with variables...

[hivelaser]

t=0.25s (blinking reflex for the eye)
and i assume a d=7mm (0,7cm or r=0.35cm) eye pupil

i guess the Joules/cm2 i calculate with the Irridance
Example i measure 12mW

so the equation would be like this
MPE = 1.8 * (0.25 / 0.75) * 0.001 * (12 * (3.1415926 * (0.35 * 0.35))

is that correct, please let me know...
