The characterizationof blood sugar using a photoacoustic imaging system is one example of an innovative application of this technology in the medical world. Blood sugar concentration is one parameter that is currently not easy to observe. However, there are other methods to observe it. One way is to use a phantom model. Phantoms are used to imitate human tissue or blood vessels. This study investigated whether a photoacoustic imaging system based on a diode laser and condenser microphone could image polyvinyl chloride and blood vessel phantoms. Research has been conductedusing a photoacoustic imaging system based on an 808nm near-infrared (NIR) diode laser and condenser microphone to image polyvinyl chloride and blood vessel phantoms. The polyvinyl chloride phantom represents soft tissue in the form of muscle. The blood vessel phantom varies in blood sugar concentration to represent the blood sugar phenomenon. The results of the system settings show that the optimal laser modulation frequency is 13.000Hz and the optimal duty cycle is 50%. The images of the polyvinyl chloride phantom and the blood vessel phantom can be distinguished well. The higher the glucose content in the blood vessel phantom, the lower the acoustic intensity. The average acoustic intensity level values obtained from phantoms with normal glucose levels, prediabetes, and diabetes respectively were 135a.u, 121a.u, and 103a.u.
