LABORATORY 1 OF MEDICAL INSTRUMENTATION
Salam & Greetings ! This is the laboratory 1 for medical instrumentation subject. Student required to perform the tasks that has been given in the labsheet. First and foremost, student need to form a group of 3 people for this laboratory assignment.
From this laboratory session, student required to design, simulate and investigate characteristics of basic sensor before it is apply in biomedical instrumentation application.
An experiment has been identified to understand the fundamental of an Optical sensor which is photodiode, opto - coupler and phototransistor. Student are require to carry out an experiment and review the fundamental function as well as characteristics of an optical in several option using MultiSim of National Instrument.
By using the components that has been listed above, student used Multism 14 to conduct a simulation of the circuit.
Figure shows an ideal optical sensor using I-V converter
By using these 3 types of optic sensor, student need to placed the sensors at A2 and B2
3 types of optic sensors
The video of circuit simulation was uploaded to youtube.com. Feel free to watch and like it on youtube. This is the link of the video 😁
The Output for the Simulation
Output of signal characteristic response for Option 1 : Photodiode
Output of signal characteristic response for Option 2 : Opto - coupler
Output of signal characteristic response for Option 3 : Phototransistor
Graphs has been plotted in order to shows the output voltage, current and power for each option when resistance ranging from 0 to 10 Ohms.
Graphs for Photodiode
Graph for Opto - coupler
Graph for Phototransistor
PRACTICAL SESSION
That's all from me. Thank you !
