Latest Patents

One of his latest patents is focused on optical surveillance systems and methods. This invention provides for optical surveillance using modulated lasers or other forms of light, along with optical detection. The system includes a light source, such as a laser or light-emitting diode, and a signal generator that modulates the light source. A detector is also part of the system, which can detect the modulated light and a processor that distinguishes the modulated light from other detected light based on the modulating waveform. This technology allows for the determination of an object's presence between the laser and the detector by analyzing the obscuration of laser pulses.

Another significant patent by Zhang is an optical amplifier for microwave bursts. This invention describes various laser architectures that enhance the gain of optical energy while compensating for optical phase distortions in a thin disk gain medium. The optical amplifier allows for scalable high-energy extraction and gains based on multiple passes of the signal beam through the gain medium. By utilizing multiple, spatially separate optical paths, the amplifier can achieve uniform signal amplitudes by clearing out residual gain.
