New process for image enhancement by means of correction of wave optical image defects
Researchers from a German University invented a computer aided process for correction of images with partially coherent light, which fastens and simplifies conventional adaptive optics. The new process improves the results of astronomical imaging with high-resolution telescopes or imaging with high-precision microscopes. The University is offering this novel image enhancement process under license agreement.

A research group from a University in Northern Germany developed a new computer aided process which fastens and simplifies conventional adaptive optics. Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effect of wave front distortions. The invention relates to a numerical correction process for digital images, for which at least partially coherent light has passed through imaging optics with predetermined image defects. The image defects above all affect the path length of the light components passed through and lead to a distortion of the light wave fronts. Conventional image enhancement processes for incoherent light are based solely on measured light intensities and cannot take the interference occurring with spatially coherent light into consideration. A wave front reconstruction is intrinsically required for this to first determine the image defects and then compensate for them. As a result an astigmatic (defocused) image can be generated with focus and without distortion from the defective image. The new process improves the results of adaptive optics used for : - astronomical imaging with high-resolution telescopes - medical application (as retinal imaging with high-precision microscopes) - high performance laser - laser cutting appliance The University has applied European and worldwide patents (EP and PCT patents) for this invention. To open up the market the researches are offering their novel image enhancement process worldwide under license agreement. They are open for partners from industry and research.
Advantages and innovations
- The new computer aided image enhancement process improves conventional adaptive optics as it takes the interference occurring with spatially coherent light into consideration and generates a focused image without distortion from the defective image. - The new image enhancement process increases the results of optical systems used in astronomy, medical and laser technology.

How it works
- Tell us about yourself
- We’ll discuss with you
- We put the right partners in touch
EEN help you find the right partner, rather than you going it alone.
Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.
These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.
Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
First we need to check you’re human.
