Single-Transducer, Three-Dimensional Laser Imaging System and Method

Previously, the field of three-dimensional imaging has mainly relied on multiple sensors or transducers to capture and compute the spatial aspects of an object. There was a constant requirement for improved imaging techniques and systems that could provide enhanced accuracy and ease of application, particularly in areas where multi-transducer systems may not be practical. Current approaches often involve complex systems that utilize multiple transducers, leading to increased costs, complexity, and size. Furthermore, many of the existing imaging techniques often suffer from accuracy limitations, specifically in capturing remote or deep-seated objects. Therefore, a technology capable of offering high-quality 3D imaging through a simpler, less complex, and more cost-efficient system has been sorely needed.

Technology Description

The disclosed invention involves a system and method leveraging a single transducer for three-dimensional image creation. By employing carefully calibrated short pulses at different wavelengths, the technology is able to map and measure various aspects of an object in a target volume. An integral component of this technology is a dispersive element that spatially separates the pulses to different spatial locations based on their wavelengths. The uniqueness of this technology is rooted in its single-transducer design and clever use of laser pulses with distinct wavelengths, wherein returned pulses are measured for time of arrival, providing range data for each pulse. This approach allows for the reconstruction of a comprehensive 3D image. In essence, the distances to various portions of an object in the target field are determined by their corresponding emitted pulses, creating a three-dimensional representation.
