Tomohiro Maeda is a notable inventor based in Brookline, MA (US). He has made significant contributions to the field of imaging technology, particularly through his innovative patent.

Latest Patents

Maeda holds a patent for "Methods and apparatus for gigahertz time-of-flight imaging." This invention describes a time-of-flight imaging system that outputs light with a modulation frequency in the gigahertz band to illuminate a range target. The high-frequency illumination enables extremely precise depth measurements, potentially down to the micron scale. The system modulates reflected light from the range target to create a beat tone with a frequency in the hertz band. In some implementations, the modulated light in the gigahertz band is generated by a first modulator, while the beat tone in the hertz band is produced by a second modulator. Additionally, the system may utilize an upshift cascade of modulators for the gigahertz band and a downshift cascade for the hertz band. A photodetector measures the low-frequency beat tone, allowing for the extraction of the signal's phase and the depth of the range target.
