Topcon had one patents in connectivity during Q2 2024. The patent filed by Topcon Corp in Q2 2024 describes a full-range imaging method that effectively doubles the imaging range by reconstructing phase information of the detected signal using an averaging technique based on modulated phase induced during scanning. This innovation eliminates mirror images of imaged objects that typically limit conventional imaging techniques to a “half-range.”.

Application: Enhanced full range optical coherence tomography (Patent ID: US20240142307A1)
The patent filed by Topcon Corp describes a full-range imaging method that aims to double the imaging range of conventional techniques by eliminating mirror images that limit the range. This is achieved by reconstructing phase information of the detected signal using an averaging technique based on modulated phase induced during scanning. The method involves scanning an object with incident light, optically modulating the phase of the interference signal, detecting the modulated signal, reconstructing the phase based on the modulated phase, and generating a full-range image based on the reconstructed phase and the amplitude of the detected signal.
Additionally, the method includes inducing positive and negative phase modulations in a single B-scan, separately reconstructing the phase based on these modulations, and generating positively and negatively tuned images that are combined to create the full-range image. Various techniques such as inducing a pr/2 phase shift, rotating a phase galvo, or switching light paths through a photonic integrated circuit are employed to modulate the phase. The reconstruction of the phase is based on intensity signals of A-lines or B-scans, with the representative phase being determined from sets of at least four data elements. The full-range image is generated by performing a Fourier transform on a complex signal derived from the intensity signals.
