Visionary Image Processing Systems

Our company is a leader in the development of optical image processing systems. Our comprehensive integrated solutions play a pivotal role in achieving remarkable outcomes in the rapidly evolving domains of machine vision, machine learning, and computational neural networks.

Without sophisticated optics and image processing systems, machines and computers are unable to see or interpret their environment. We fill this gap by developing customized imaging systems to meet your computer vision inspection tasks.

Machine Vision

Image processing systems consist of at least three components: Lighting, lens, camera. Our knowledge and experience enable us to realize specific image processing scenarios from the above-mentioned components. Depending on the required process parameters, we make use of available technologies: intelligent camera systems and telecentric or entocentric lenses, with or without filters; types of illumination ranging from VIS light sources, LEDs and lasers to IR light and UV radiation.

Image Processing Applications

Optical inspection tasks based on imaging processes are now considered industry standard. We have a strong focus on implementing the most sophisticated solutions that go beyond the usual standards. Depending on the application, any 2D information can be determined using conventional image processing. This includes shape and size determination, position detection, OCR, QR, or data matrix code reading, color measurement, and cleanliness inspection. We are proud to offer even real-time evaluation with high temporal resolution as part of our state-of-the-art services.

Image Processing Technologies

Digital image processing technologies offer a range of possibilities that extend beyond traditional methods. The focus is not on the intensity or light distribution, but on other parameters of the light. Wavelength-dependent image processing allows for the breakdown or conversion of RGB images into other color spaces, such as LAB, ultraviolet, infrared, and thermography, or entire spectra, as seen in hyperspectral imaging. In other instances, the polarization of light enables the visualization of otherwise invisible material properties.

Characterization of Image Processing Systems

Characterization of Image Processing Systems

It is important to note that no optic is perfect. In the case of imaging optics, it is often necessary to assess the extent of any imperfections, for example in terms of distortion, modulation transfer function (MTF) or contrast. This characterization is conducted using measurable targets. We develop a range of targets for use in a variety of applications, including 3D targets, MTF targets, distortion and reflection targets. This approach ensures that optical inspection and measurement systems achieve optimal results and that 3D glasses display images without distortion.

Projects

Characterization of Eyepieces for AR Glasses

Characterization of Eyepieces for AR Glasses

Even with "immersive" technologies such as augmented reality (AR), image quality is governed by "real" optical laws. It is essential to measure and correct the distortion of the two eyepieces in order for AR glasses to accurately convey the impression of three-dimensional vision. This is accomplished through the automatic analysis of a calibration target designed for the eyepieces. The distortion and modulation transfer function (MTF) of the eyepieces are measured and compared with simulations. A correction matrix is then output, which enables the subsequent correction.

Image-Based Testing of Contact Lenses

Image-Based Testing of Contact Lenses

We have developed a precise and practical testing system for examining the drying behavior of contact lenses. A combination of coaxial and dome illumination enables the visualization of thin-film interferences on contact lenses. The camera and lens, in conjunction with image analysis software, evaluate the interference and calculate the drying time of the contact lens. Furthermore, any defects in contact lenses or their coating are identified and evaluated. To streamline the testing process, contact lenses can be moistened via a reservoir, allowing for repeated measurements.

Testing and Alignment of IR Optics

Testing and Alignment of IR Optics

When testing IR optics, it is essential to ensure that the light source, the optics of the test system, and the detectors cover a wavelength of 2,000 nm to 5,500 nm. Filters, broadband light sources, and reflective optics are employed for this purpose. Our inspection system enables the light source to be positioned in front of the lenses at different spatial angles and positions, allowing for comprehensive analysis of the lens image field and alignment verification. The results of the measurements (MTF and PSF) are then documented in a quality control report for the customer.
