TRAJECTORY BASED 3D FRAGMENT TRACKING IN HYPERVELOCITY IMPACT EXPERIMENTS
Hypervelocity impact Space debris Fragmentation Particle tracking Trajectory fitting Stereo matching
2018/6/5
Collisions between space debris and satellites in Earth’s orbits are not only catastrophic to the satellite, but also create thousands of new fragments, exacerbating the space debris problem. One chal...
Scattered Pilot Channel Tracking Method for PDM-CO- OFDM Transmissions Using Polar-Based Intra-Symbol Frequency-Domain Average
Fiber optics communications Modulation
2015/5/25
We have demonstrated an efficient scattered pilot channel tracking approach with a new polar-based intra-symbol frequency domain average (ISFA) for 16-QAM, 40-Gb/s PDM-CO-OFDM systems. This proposal c...
A Novel Synchronous Coherent Optical Receiving Technique without Active Phase Tracking
Receiving Technique Phase Tracking Novel Synchronous Coherent
2015/5/18
A novel synchronous coherent optical receiving technique is proposed. With this technique, active phase tracking with an optical phase locked loop is eliminated by canceling out the phase and frequenc...
A Self Wavelength Tracking Method for a Cost Effective WDM-PON with Tunable Lasers
Optical communications Networks
2015/6/10
We demonstrate a self wavelength tracking method for tunable lasers in a WDM-PON.By measuring the back-scattered power by a feeder fiber, we identified and tracked the allocated wavelength of the tuna...

Fiber Optic Communications Polarization
2015/6/8
We report agile endless optical polarization demultiplex, free of polarization channel jumps, over a 475 Mrad long Poincaré sphere trajectory at 10 krad/s speed, in a 50-Gsymbol/s,4-bit/symbol realtim...
Tunable Single-Longitudinal-Mode Fiber Optical Parametric Oscillator with Saturable-Absorber-Based Auto-Tracking Filter
Nonlinear optics fibers Parametric oscillators amplifiers
2015/6/4
A tunable single-longitudinal-mode (SLM) fiber optical parametric oscillator is demonstrated by using a subring cavity and a fiber loop mirror incorporated with a saturable absorber. It can provide du...

Benefits Decorrelated Color Information Face Segmentation Tracking
2009/5/19
We analyze in this paper the benefits that can be derived from employing color image alignment techniques in the context of face segmentation or tracking based on texture (defined as the patch of inte...
The application of the self-adaptive tracking method to the sinusoidal phase modulating interferometry
sinusoidal phase modulation surface profile measurement
2011/5/6
In this paper, we analyze theoretically the accuracy of the surface profile measurement in a sinusoidal phase modulating interferometer, derive the relative error formula, and investigate the influenc...
Realtime 40 krad/s Polarization Tracking with 6 dB PDL in Digital Synchronous Polarization-Multiplexed QPSK Receiver

2015/8/3
Fast polarization changes of 40 krad/s (and 6 dB PDL) are tracked in a 2.8 Gb/s realtime coherent QPSK receiver with 0.7 dB (2.4 dB) sensitivity degradation.
In this paper, we use the optical-type eye tracking system to control powered wheelchair. The userís eye movements are translated to screen position using the optical-type eye tracking system. The pup...
