“…However, in more complex environments, the use of other techniques, such as the ray tracing [13] or computational electromagnetics software, may be necessary. Moreover, during the propagation, the signal is attenuated and distorted due to the free space path loss and the reflections and delayed due to the propagation time.…”

Communications are becoming the bottleneck in the performance of Chip Multiprocessor (CMP). To address this issue, the use of wireless communications within a chip has been proposed, since they offer a low latency among nodes and high reconfigurability. The chip scenario has the particularity that is static, and the multipath can be known a priori. Within this context, we propose in this paper a simple yet very efficient modulation technique, based on Impulse Radio -On-Off-Keying (IR-OOK), which significantly optimizes the performance in Wireless Network-on-Chip (WNoC) as well as off-chip scenarios. This technique is based on interspersing information pulses among the reflected pulses in order to reduce the time between pulses, thus increasing the data rate. We prove that the final data rate can be considerably increased without increasing the hardware complexity of the transceiver.

“…Optical modeling techniques are widely used to determine the optical collection of LSC-PV modules (Spencer and Murty, 1962). A three-dimensional model was built employing ray tracing to model the effect of several design parameters on the collection efficiency of the LSC-PV Fig.…”

“…The paths of the light rays can be determined accurately with elementary geometry and by successive applications of the law of refraction (or reflection); this method is known as ray tracing and is the most important current simulation method for macroscopic optical systems. The principle of ray tracing through refractive and reflective optical elements is well known [17][18][19]. The optical path length of a ray is calculated from the point of intersection of the ray with the surface of the plane of localization, where the rays meet to interfere.…”

This paper describes the surface form measurement of a spherical smooth surface by using single shot off-axis Fizeau interferometry. The demodulated phase map is obtained and unwrapped to remove the 2π ambiguity. The unwrapped phase map is converted to height and the 3D surface height of the surface object is reconstructed. The results extracted from the single shot off-axis geometry are compared with the results extracted from four-frame phase shifting in-line interferometry, and the results are in excellent agreement.
