Course detail

Special Sensors

FEKT-MSPSAcad. year: 2017/2018

The course deals with the principles of the most widely used semiconductor, optoelectronic and fiber-optic sensors. Students will learn characteristic constructions of sensors, the basic technological processes in their production, typical characteristics, parameters, usage, applications and limitations of sensors. Emphasis is also placed on familiarization with types of output circuits, data processing and signal processing from the output of these sensors . There will be discussed also a requirements for smart sensors (eg. methods of diagnostics, calibration sensors) and MEMS sensors. Students will gain practical experience with selected semiconductor photoelectric sensors and fiber in the laboratory exercises.

Learning outcomes of the course unit

The student will be able to explain the principles of semiconductor, optoelectronic and fiber-optic sensors, define the characteristics of intelligent sensors. He will be able to decide on the appropriate choice of the sensor for the particular application with respect to their characteristics and limitation. Student will be able to design circuits for signal processing from these sensors and perspectively also plan and implement a measurement chain in the real applications.

Prerequisites

The student who enrolls this course should be able to explain the basics of semiconductor physics and optics, describe the basic principles of sensors, able to analyze and identify the electronic circuits used in the sensing and measurement technology, apply basic methods of measurement of electrical quantities (voltage, current, resistance, capacitance, inductance) and be able to assemble measuring chain with instruments as oscilloscope, function generator, DAQ cards for measuring of analog and digital signals and be able to prepare and use the LabVIEW developing tool. This course follows to courses in undergraduate studies BMVE and BSNI. Student should have such language skills to understand some educational materials in English.

Aims

The goal of the course is to introduce and deepen students knowledge of selected types of semiconductor, photoelectric, fiber-optic, MEMS (micro-electro-mechanical), MOEMS (micro-opto-electro-mechanical) and intelligent sensors. Students will become familiar with their use in real applications, such as measurement, navigation, robotics, etc. The aim is to create an overview for students to understanding of the use of the relevant physical phenomena, measuring methods and concepts of these sensors.

Specification of controlled education, way of implementation and compensation for absences

Definition of controlled education will be established by announcement published by course supervisor every year. Mandatory participation in laboratory exercises, in case of absence the exercise work can be supplemented with alternative exercise in same week or with a self-study of additional literature.
