MIT summer short course on high-speed imaging

MIT short course

We are excited about the opportunity to participate at MIT Edgerton Center’s Short Course about high-speed imaging on June 17- 20 this summer, and to give again a presentation about laser illumination.

The 4-day course is organized by MIT Professional Education in Cambridge, Massachusetts and presents an extensive coverage of high-speed imaging for motion analysis as well as various systems and techniques.

You can find more information from the organizer’s webpage: https://professional.mit.edu/programs/short-programs/high-speed-imaging

You can also sign up for the course under the above mentioned link and secure your chance of learning more about the fascinating world of high-speed imaging.

Additive manufacturing with laser and powder-bed

additive manufacturing

One of the most applied additive manufacturing method for metals is based on a laser scanner and a powder-bed where the metal powder is distributed over a tray and the processing laser melts it according to the desired pattern. After the pattern is created, a new layer of powder is added and the process repeats. The process enables accurate processing and elimination of spatter is essential. High-speed imaging with CAVILUX laser illumination provides high-quality images of the process.

Visualization of a discharge of an electrical switch (16 A, B curve) at 2000 frames per second. Electrical switches are key safety components in many systems. High-speed imaging is used to study their operation. Choosing the right lighting matters. The left video shows the process illuminated with a halogen light. Motion blur and the arc are visible reducing the quantity and quality of information. With CAVILUX laser illumination the arc is suppressed and motion blur eliminated thus providing clear images.

Submillimeter ice crystal formation at 6 km altitude

Image of submillimeter ice crystal formation at 6 km altitude. The image is taken with special measurement system installed at the wing of an airplane. Due to the high velocity of the plane, capturing the ice crystals without motion blur requires a very short camera shutter or light pulse. CAVILUX is used in the setup as illumination because of its ability to create very short light pulses.

Great experience from short course on high-speed imaging at MIT Edgerton Center

Cavitar would like to thank MIT Edgerton Center for organizing the Short Course about high-speed imaging in June this year and the possibility to share our knowledge about laser illumination.

During the 4-day course the participants gained a wide knowledge about high-speed imaging and motion analysis. The topics covered cameras, optics, illumination, software and other relevant topics. After the theory lessons the participants were able get hands on experience with imaging systems in different lab works.

During the lab session about strobe lights, course participants were able to take an image of their business cards shot by a rifle bullet. With a digital camera, a power full strobe light and the correct triggering one got fascinating images.
