||The main purpose of this paper is to build a new system of non-invasive optical measurement for quantizing tremor of hands. This system contains projector, camera, computer and MATLAB.|
This system build Moiré pattern by post-production, and calculate the frequencies on hands by MATLAB. According to the value of image, we can transfer to frequency domain so that we can quantize tremor of hands.
The study uses digital Moiré to build a system for measuring tremor of hand. The system can digitize the tremor of hand and plot spectrogram by doing Fourier transform to grayscale of interested point. Doctors can judge efficacy of treatment by objective data and reduce misjudgment by patient oral discussion.
We compared 15 patients of their spectrogram before and after treatment. And these 15 results are diagnosed with doctor that have efficacy of treatment. In these 15 results, there are 13 results are effective, 1 result is unknown and 1 result is worse. It’s high accuracy to recognize whether the treatment works.
