Large optical image rotation for project

[pex]

Hi, fellow physics friends!

I'm doing a small interior decoration project in which I need optical image rotation as a component. I know that this can be done (see e.g. http://www.optics.arizona.edu/optomech/papers/swift%201972.pdf for a review paper). I've also seen Half-Penta Prisms sold online that do this.
However, a 25mm HPP costs $135. I want one which is about 1 meter in size, but on the other hand I have very low requirements on quality (a bit of optical disturbance is just positive) and the image need not be rotated 45 degrees (less or more is fine).

Question: is it realistic to attempt to construct one myself? How would I go about to do this? I do have access to a small engineering lab at my local university. What material would you recommend?

Note: The project is not to construct a death star with a death ray with which I can destroy planets insolent enough to defy my imperial will.

thsi is some codes about image rotate, not sure if it is what you are asking for.
Imports System.IO
Imports System.Drawing.Printing
Imports RasterEdge.Imaging
Imports RasterEdge.Imaging.Processing

Dim Image As New RasterEdgeImaging()

Public Sub RotateImage()
If True Then
Dim LoadImage As New Bitmap("C:\\1.bmp")
Dim rotate As Graphics = Graphics.FromImage(LoadImage)
rotate.TranslateTransform(CType(bmp.Width, Single) / 2, CType(bmp.Height, Single) / 2)
rotate.RotateTransform(rotationAngle)
rotate.TranslateTransform(-CType(bmp.Width, Single) / 2, -CType(bmp.Height, Single) / 2)
rotate.InterpolationMode = InterpolationMode.HighQualityBicubic
rotate.DrawImage(img, New Point(0, 0))
rotate.Dispose()
Return LoadImage()
End If
End Sub

Well, nuts! I was all-in and even would have sponsored you until you dropped that little nugget of bad news... :tongue:

By the bye, your link goes to "Page Not Found".

the link dint work for me,

im not sure if this is what you mean but...

if your trying to displace and/or re-orient a projected image then
i think you could make an acryllic prisim with a seconday trapizoidal prizim inside
trial and error would tell you how to set it up right but it should redirect, reorient and even distort the image if wanted

im not sure what actual material and/or shape a prizim might have to be though

for some reason i want to believe it would work in a similar maner as the mirrors of a parascope
whereas the edge/sides would be potential mirrors

I would recommend caution when attempting to construct a large optical image rotation device yourself. While it is possible to construct a simple optical image rotator using inexpensive materials, achieving a high level of precision and stability may be difficult without proper equipment and expertise. The optical disturbance you mention may also be more significant than you anticipate, potentially affecting the quality of your project.

If you do decide to proceed with constructing your own optical image rotator, I would recommend using materials with low thermal expansion and high mechanical stability, such as fused silica or low-expansion glass. You may also want to consult with an expert in optics or engineering to ensure that your design is feasible and to receive guidance on the construction process.

In addition, I would suggest considering alternative solutions such as purchasing a pre-made optical rotator or exploring other methods of achieving the desired effect for your project. This may save you time and effort in the long run and ensure a higher level of precision and reliability.

In conclusion, while it may be possible to construct a large optical image rotator yourself, it is important to carefully consider the potential challenges and limitations before proceeding. Consulting with experts and exploring alternative solutions may ultimately lead to a more successful and cost-effective outcome for your project.
