Abstract
In our work, we have been emphasizing the use of focused beams — both optical and acoustic — as a method for obtaining high resolution images. We work with acoustics in the microwave range and use our set-up for the acoustic microscope to receive the thermally generated signal. Mechanical scanning is used to form the raster pattern. With a cavity-dumped laser which provides us with 25 microsecond pulse at repetition rates of 1 MHz, we are able to record the image in a few seconds.
