Avdelningen för Strömningslära och Experimentell mekanik har tillsammans med
avdelningen för Material- och Solidmekanik valt att investera i ett gemensamt laboratorium
för avancerad mekanikforskning.
A modern high-speed camera system which is financed by the Kempe Foundations. The numbers of pixels are 1280x1024 and 2000 images per second, with full resolution, can be recorded .
A modern high-speed IR camera system financed by the Kempe Foundations has been purchased. The number of pixels are 320x256 and the sensitivity is around 25mK.
A laser Doppler Vibrometer (LDV) is a non-contact vibration velocity (or displacement) transducer which uses the Doppler shift of back scattered laser light (He-Ne, of wavelength of 633 nm) from a moving surface.
The versatile laser system can be used in a number of applications. Since the system is injection seeded the two laser cavities are coherent and holographic recordings can be made.
This light source can deliver 2 μs light pulses at 10 kHz frequency or 100 ns light pulses at 200 kHz frequency. The wavelength is 810 nm and the light can be launched in a fibre optic cable and optics to create a suitable illumination spot. The laser is easy to synchronise with a high-speed camera.
