Avdelningens laboratorier och utrustning

The John Field Laboratory

Avdelningen för Strömningslära och Experimentell mekanik har tillsammans med
avdelningen för Material- och Solidmekanik valt att investera i ett gemensamt laboratorium
för avancerad mekanikforskning.

Experimental Equipment

To aid the quality and trust of computer simulations experiments are important. Our laboratory contain advanced equipment for measuring flow, velocities and pressure by various methods.

3D-avbildningssystem: Röntgenbaserad mikrotomografi

Röntgenbaserad mikrotomografi används för att göra en fullständig 3D avbildning av ett föremål, utifrån ett visst antal röntgenbilder som tas från olika vinklar.

Digitala kameror

Laser Doppler Vibrometer (LDV)

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.

Pulsat Nd:YAG lasersystem

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.

Rubinlaser

The ruby laser is a double pulsed laser used for pulsed holographic interferometry (using film) and pulsed TV holography (using a PCO digital camera).

Infraröd kamera FLIR SC 4000

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.

Pulsed diode laser light source Cavitar HF

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.
