How to convert your image into a Mem-Gem

The process to convert your image into a Mem-Gem involves three main steps: image selection, simulation, and manufacturing.

 

Image Selection

The first, and arguably most difficult step, is selecting an image!

Personally, I asked my wife (girlfriend at the time): "what's your favorite image of us together?" and then I used that one! She had no idea I was designing a Mem-Gem :D

Typically, you want a high-contrast image where your subject occupies most of the bandwidth of the image. What won't work very well is an image where your subject is poorly lit, with a bright background with lots of sharp contrasting features. On the other extreme, an oversaturated image will not work very well either. Some customers have had success photoshopping or blurring the background of their images to increase the bandwidth of their subject.

Simulation

You can upload your image here:

First, upload your file. Then, select square or round edges, or something in-between. Then, adjust the sliders to get a good brightness and contrast. You can stop here, and submit your image.

As part of developing Mem-Gems, we have created proprietary software that uses our patent-pending technology to convert images to Fourier-transform simulations. If you really want to get fancy (advanced users only!!), you can use the advanced simulator by clicking this button 12 times:

The advanced simulator will create a very realistic rendering of what your eventual projection will look like, by using proprietary Fourier-transform simulation optics. This is a great way to experiment with different images and filters to see what gives the best resulting projection with a Mem-Gem.

 

Manufacturing

Once you have uploaded your image, we will convert it into a phase-mask and start the manufacturing process to etch it into a laboratory-grown sapphire wafer.
