An optical module

ActiveCN224457076UThe same amount of thermal expansionavoid stressOptical ModuleFiber array
The optical module disclosed herein includes a circuit board, a substrate, a laser, an optical modulation chip, and a fiber array. The substrate surface is prone to rusting; therefore, a protective layer can be formed on the substrate surface. A first connecting plate is provided between the substrate and the fiber array. A first thermosetting interface layer is formed between the bottom surface of the first connecting plate and the protective layer, and a first photocurable interface layer is formed between the top surface of the first connecting plate and the fiber array. The first thermosetting interface layer increases the interfacial bonding energy between the protective layer and the first connecting plate, thereby increasing the adhesion between the substrate and the first connecting plate. The first photocurable interface layer is formed by low-temperature curing, thereby preventing the fiber array from deforming due to high temperatures. The first photocurable interface layer has a low shrinkage rate, preventing the fiber array from deforming due to stress, thereby reducing the optical path offset of the fiber array. The bottom and top surfaces of the first connecting plate form different interface layers, satisfying both the adhesion between the connecting plate and the protective layer and ensuring that the fiber array has a low optical path offset.

A Transformer-based multimodal indoor 3D scene understanding method

This invention provides a Transformer-based multimodal indoor 3D scene understanding method. Based on a newly proposed multimodal indoor 3D scene understanding mechanism, it combines geometric structural information from the 3D scene with semantic constraints from natural language to effectively filter and enhance the features of question-related targets. Furthermore, a unified network enables the joint output of semantic understanding and spatial localization within the indoor scene, thereby improving the accuracy and robustness of indoor 3D scene understanding. This addresses the problems in existing technologies, such as the difficulty of 3D detection models in understanding natural language semantics, the difficulty of 2D question-answering models in utilizing 3D spatial structural information, and the insufficient correlation between targets and text in existing sequential solutions.
