Sound and ultrasound sensors

Ovim je završnim radom opisana fizika zvučnog i ultrazvučnog vala, načini njihovog nastajanja, rasprostiranja te primjena ultrazvuka u pomorstvu, automobilnoj industriji te medicini. Danas je gotovo ne zamislio bočno parkirati auto bez zvučnog signala o udaljenosti od rubnjaka, otići u ribolov bez fish findera ili pak čekati dijete do njegovog rođenja bez da znamo kojeg je spola, a odgovor na sva ta pitanja nam daje ultrazvuk odnosno usmjereni ultrazvučni valovi, nastali ultrazvučnim generatorima te odaslani i primljeni preko ultrazvučnih senzora.This final thesis describes the physics of sound and ultrasound waves, the ways of their generation, propagation and the application of ultrasound in the maritime, automotive industry and medicine. Today, we can hardly imagine parking our car without an audible signal which warns us of the distance from the curb, going fishing without a fish finder, or waiting until the child is born just to know its gender, and the answer to all these questions is provided by ultrasound, i.e. directed ultrasound waves. generated by ultrasonic generators and sent and received via ultrasonic sensor
