PPT-Ultrasound Microscopy and High Frequency Coded Signals

Antti Meriläinen Edward Hæggström Using high frequency acoustic waves for mmµmscale imaging Method is nondestructive It Sees inside the sample Ultrasound images differences of acoustic impedances. This number representation uses 4 bits to store each digit from 0 to 9 For example 1999 10 0001 1001 1001 1001 in BCD BCD wastes storage space since 4 bits are used to store 10 combinations rather than the maximum possible 16 BCD is often used in b Lecture . 07: .

Microscopy is the technical field using microscopes to view samples and objects that can not be seen without unaided eye (objects that are not within the resolution range of the normal eye). There are three well-known branches of microscopy: optical, electron and scanning probe microscopy..

It produces greatly enlarged images of minute objects. LIGHT MICROSCOPE A Light Microscope can be simple or
