FOURIER TRANSFORM PROFILOMETRY WITH A DUAL READOUT SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240340404 titled 'FOURIER TRANSFORM PROFILOMETRY WITH A DUAL READOUT SENSOR
Simplified Explanation
The patent application describes a system for three-dimensional object sensing using fringe-projection profilometry with Fourier transform analysis. This system projects frequency signal patterns onto an object's surface and captures reflections to generate a wrapped phase map for reconstructing the object's surface in 3D.

Original Abstract Submitted
a system for three-dimensional object sensing using fringe-projection profilometry with fourier transform analysis is described. a fringe-projection profilometry (fpp) projector simultaneously transmits a frequency signal pattern (i.e., modulated or ac signal) and a zero-frequency signal pattern (i.e., unmodulated or dc signal) onto an object's surface. alternatively, the projector projects two frequency signal patterns phase-shifted by 180 degrees. a dual readout sensor captures reflections of both signals from the object's surface as adjacent frames, and the dc signal is extracted by subtraction of addition to obtain an enhanced signal. the enhanced signal is used to generate a wrapped phase map through fourier transform profilometry (ftp). the resulting wrapped phase map is unwrapped, and three-dimensional reconstruction of the object's surface is generated by converting phase from the unwrapped phase map to three-dimensional coordinates.
