Compact Fourier‐Transform Spectrometer on Thin‐Film Lithium Niobate via Mode‐Circulating Modulation

Advanced Photonics Research, Volume 7, Issue 8, August 2026.
Schematic diagram of the proposed compact on‐chip Fourier‐transform spectrometer on thin‐film lithium niobate that exploits mode‐circulating electro‐optic modulation, in which guided light is sequentially converted among multiple spatial modes to accumulate multiple phase modulation events within a single physical modulation arm.

Enhanced Monocular Depth Estimation Using ResNet Backbone and Multiscale Feature Decoding for Precise Object Distance Measurement

Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.
A lightweight monocular perception framework generates high‐fidelity depth maps and integrates YOLOv8 detection to estimate object‐wise distances from a single RGB image. Evaluated on KITTI and the proposed D‐Far250 dataset, the system demonstrates accurate long‐range perception up to 250 m while maintaining real‐time performance, enabling scalable ...
