Polynomial Aspheric lens ray tracing

[brl]

Hi all,

Does anyone knows where I can find a good guide for Polynomials Ray Tracing?

I have seeing several ray tracing sequences, such as the one done by the Late Darryl Meister for espherical and aspherical conicoids, also others for toric and atoric conicoids and even one done by Don Whitney on polynomials.

But I have never seen a full ray tracing calculation sequence for polynomials. Any direction about where to find it will be welcome.

Thanks in advance!

Absolutely flies 10,000 miles over my head.

However, I would like to interview you for Optiboard.com "get to know a new poster"!

First of all, are you an optical engineer? An optician? A lens manufacturer?

Hi dkr!

I've worked in some positions from lab to lens manufaturer.

I sent you a PM.

Rergads,

In the menu go to the Ray Tracer application, it allows for aspheric ray tracing from surface only but it could use an update to a back surface aspheric instead given the current fabrication methodologies. It allows for adjustment of all parameters including the main trace eye rotation, but if you want to see other angle you can click on the graphic and see tangential and sagittal errors at any point of rotation of the eye.

Polynomial is not that complex just use the dy/dx to calculate the lens plane at the point the ray is incident with the polynomial surface and its standard snells after that.

Hi Harry!

Thanks for your input.

I didn't know the ray tracing you pointed above and I'll test it as soon as possible.

I also have also done some tools to calculate ray tracing, for front and back aspheric lenses and other stuffs, including the SDF files.

Regading the polynomial lenses, I confess that it's been a little more dificult to me. Although we can convert from conicoids to polynomials and vice versa, I would like to see a complete ray tracing trough a polynomials that causes a deformed conicoid to.

In this post I tried to get directions to some references on polynomials ray traicning, since I have not found much about it.

Thak you again for the calculator direction.

Best regards,

[HarryChiling]

I'll see what I can dig up as reference if you have an example that would be helpful to post.

This is probably better through direct message.

Hi Harry!

I will send you a private message.

Thanks!
