Presentation About Precise Distance Measurements with Ultrasonic/Optical Pulse Sensor

Inside the presentation we can get explanation around time distance, sound, ultrasonic transit, pulse, distance sensor, sensor, transit time, and distance. The presentation presents explanation about technique, transmitter, receiver, ultrasonic transit time, transducers, optical pulse, and echo.

Many discussion related to optical sync, ultrasonic, ultrasonic pulses, ultrasonic, signal, circuit, and pulse shaping are explained inside this presentation. Here are selected from this presentation:

Ultrasonic Transmitter/Receiver Transducers Transducers are piezoelectric crystals (quartz, ceramic, piezofilm) Single or separate transmitter and receiver transducers may be used Typical Frequencies used for air transmission are 40 to 100 kHz Single pulse produces ringing because of crystal mechanical resonance Often a pulse train (4 to 20 cycles) is applied to transmitter to increase transmitted sound amplitude

Additionally, the presentation gives us more around ultrasonic sensor, shaping, receiver transducers, pulses, position, echo sensors, and transit time distance.
