In this paper, the first detection result of coherent scatterers (CSs) in forest environment is addressed. As a scatterer associated with CS, the dihedral structure consists of the tree-trunk like a vertical cylinder and the ground surface is assumed. The potential of CSs as being the phase stable scatterers as permanent scatterers will be also demonstrated with P-&L-band Pol-InSAR datasets acquired...
We describe a novel compact real-time single-shot full-field optical coherence tomography based on a dual-channel phase-stepper optics, which employs a 2-D quaternionic analytic signal processing technique to reconstruct en-face OCT images for biological samples.
A multicore system-on-chip (SoC) has been developed for various applications (recognition, inference, measurement, control, and security) that require high-performance processing and low power consumption. This SoC integrates three types of synthesizable processors: eight CPUs (M32R), two multi-bank matrix processors (MBMX), and a controller (M32C). These processors operate at 1 GHz, 500 MHz, and...
Two ALOS/PALSAR polarimetry data taken in 2006 were used and examined the deforestation stage by using coherence value. Many trees were fallen by a typhoon hit on September 8, 2004 at a test site in Japan. Reforestation has started for the deforestation sites and several kinds of deforestation stages are appeared there. We classified the stands into four groups. 1) Only small stumps and branches are...
We developed a new directional borehole radar system with an array of optical electric field sensors as receivers. The system was tested in a field test site in order to assert its ability to detect three dimensional (3D) location of a subsurface tunnel. In this paper, the result is shown with a comparison to a result obtained by RAMAC directional borehole radar system. It is found that the optical...
We demonstrate three-dimensional imaging by wide field optical coherence tomography with high-speed CMOS camera. A sample volume of 2.3times2.3times1.1mm3 (corresponding to 256times256times300 pixels) was imaged at 10 volumes/s by the scanning reference mirror.
We demonstrated in vivo cross-sectional imaging of human fingers by non-mechanical scanning optical coherence tomography, using a diffracted light as the reference beam and a linear illumination beam, at a center wavelength of 1.3 mum.
We first demonstrate the application of maximum entropy method (MEM) to Fourier domain OCT to obtain axial profiles. Using an Onion as sample the spatial resolution has been enhanced by MEM with the order of 170.
