We propose a Fourier transform-based 3D profile-acquisition method. Since the proposed method is employed in the spatial frequency domain, the 3D retrieval process can be performed effectively using a fast Fourier transform (FFT) algorithm even if a deformed grating pattern uses a high-resolution image format. To accelerate the FFT computation, we implement the proposed method using a graphics processing...
Thermal test object(TTO) with embedded single thermocouple and split tissue mimicking material(TMM) measured by infrared image were compared for evaluating temperature rise and position in TMM. The result showed the average of temperature rise in TMM with thickness of 5 (mm) for 3 (min) was similar between both methods. The infrared image with split TMM was useful for evaluating the position of maximum...
