Three-dimensional imaging using a single transducer.
2D and 3D imaging applications.
To achieve higher resolution and improved capabilities such as facial recognition, there is a need for a 3D imaging system that operates with low timing jitter and good sensitivity.
The invention is a three-dimensional (3D) imaging system that uses a single transducer to detect pulses at different center frequencies to different spatial locations. A source generates a series of pulses with distinct center frequency. The pulses are coupled to a frequency-to-space converter which maps each pulse to a different spatial location based on the center frequency of the pulse. An aperture receives pulses scattered or reflected from objects at the spatial locations and couples the received pulses to a transducer, which converts the received pulses into electrical signals that represent a 3D image corresponding to the spatial locations. Suitable transducers include, but are not limited to, the transducers in Geiger-mode avalanche photodiodes, photomultiplier tubes, transition edge sensors, and superconducting nanowires.
Uses single transducer so there is no need for arrays
Has lower timing jitter than current 3D imaging
Has better sensitivity than current 3D imaging systems
