Abstract

A sample 10 is measured by generating ultrasound at 12, for example by using a laser 22 and spatial light modulator 26. The ultrasound is detected at 16, for example by optical beam deflection techniques. A characteristic of the generation at 12 is swept across a range of values to vary the efficiency of generation of ultrasound. The value of the characteristic, which corresponds with the peak amplitude detected at 16, is identified to provide a measure of the acoustic velocity at the region 12. The method is executed at a plurality of sites 12, 20 to provide a set of spatially resolved measurements of the sample 10. This allows an image of the sample to be created.
