Abstract
Description
Technical Field
[0001] This disclosure relates to the field of optoelectronic processing technology, and in particular to a reconfigurable intelligent imaging chip system. Background Technology
[0002] With the deep integration of artificial intelligence (AI) and the Internet of Things (IoT) technologies, the demand for real-time perception and intelligent processing of high-dimensional visual information is becoming increasingly urgent in edge computing scenarios such as intelligent transportation, industrial visual inspection, and augmented reality (AR). These applications require not only capturing the two-dimensional intensity information of targets but also acquiring and understanding their rich physical properties, such as angles, spectra, polarization, and other multi-dimensional light field features, in order to achieve low-latency scene understanding and task adaptation.
[0003] Currently, visual perception systems are built upon traditional digital CMOS image sensors. However, conventional CMOS image sensors are essentially intensity-response devices, capable of recording only the light intensity distribution in two-dimensional space. They cannot directly capture high-dimensional features such as spectrum, polarization, and angle, which carry crucial information about the target material, surface shape, and depth, at the optical front end. This results in a significant loss of valuable information at the sensing source. Furthermore, the process from optical acquisition to digital signal processing involves multiple photoelectric and analog-to-digital conversions, increasing system energy consumption and limiting end-to-end real-time performance and bandwidth efficiency. To address the aforementioned limitations, related technologies propose integrating "intelligent sensors + edge computing." This approach attempts to integrate lightweight computing units (such as analog computing circuits or in-memory computing arrays) within the sensor chip or near the sensing end, offloading some computational tasks to the hardware layer. While this approach alleviates the burden on the backend processor to some extent, the overall bandwidth bottleneck and power consumption issues remain unresolved because the output signal still requires pixel-by-pixel readout and conversion. Furthermore, this architecture still exhibits weak capabilities in feature fusion and collaborative processing of multidimensional information (such as spectral and polarization). Consequently, the aforementioned technical solutions struggle to simultaneously achieve efficient acquisition of high-dimensional information and flexible adaptation to intelligent tasks, resulting in poor versatility across different application scenarios. The rigid hardware architecture prevents adaptive reconstruction of optical structures or computational processes at the sensing source based on specific task requirements, severely limiting the system's versatility and robustness in complex application environments.

[0018] The above and / or additional aspects and advantages of this disclosure will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, in which: Figure 1 This is a schematic diagram of the structure of a reconfigurable intelligent imaging chip system provided in an embodiment of this disclosure. Detailed Implementation
[0019] Embodiments of this disclosure are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.
[0020] The reconfigurable intelligent imaging chip system of this disclosure will be described in detail below with reference to specific embodiments.
[0021] Figure 1 This disclosure provides a reconfigurable intelligent imaging chip system according to an embodiment of the present disclosure. For example... Figure 1 As shown, the reconfigurable intelligent imaging chip system may include a control and scheduling unit 101, an on-chip optical sensing unit 102, an on-chip signal preprocessing unit 103, and an on-chip intelligent computing unit 104, wherein... The control and scheduling unit 101 is connected to the on-chip optical sensing unit 102 and the on-chip intelligent computing unit 104 respectively, and is used to acquire the target task, and determine the corresponding first target voltage signal, the first target structure of the reconfigurable meta-chip, and the first target neural network model based on the target task. The on-chip optical sensing unit 102 is connected to the control and scheduling unit 101 and is used to regulate the reconfigurable metachip of the first target structure through the first target voltage signal to perform in-situ modulation and compression encoding of the high-dimensional light field to obtain the compressed feature value image of the light field. The on-chip signal preprocessing unit 103 is connected to the on-chip optical sensing unit 102 and is used to acquire the light field compression feature value image and preprocess the light field compression feature value image to obtain the target digital feature image. The on-chip intelligent computing unit 104 is connected to the on-chip signal preprocessing unit 103 and the control and scheduling unit 101. It is used to acquire the target digital feature image, process the target digital feature image through the first target neural network model, and output the task result.
[0022] In one embodiment of this disclosure, the target task may include at least one of digit recognition, angle reconstruction, and spectral band selection.
[0023] In one embodiment of this disclosure, the on-chip optical sensing unit 102 can be a reconfigurable metachip with a compact optical structure as a front-end information acquisition unit, responsible for completing the in-situ modulation and compression encoding of the high-dimensional light field, and outputting a compressed feature value image of the light field containing rich information.
[0024] In one embodiment of this disclosure, the reconfigurable metachip includes a metasurface image sensor to acquire an input light image. The metasurface image sensor is a liquid crystal-infused metasurface (LCIMS) image sensor, which overcomes the inherent limitations of traditional image sensor structures in terms of dimensional scalability, task adaptability, and feature response capability, and constructs an imaging system architecture with high intelligence and task adaptability.
[0025] In one embodiment of this disclosure, the above-mentioned reconfigurable metachip uses upper and lower double-layer glass to encapsulate the liquid crystal cavity to form a liquid crystal cavity. Combining electrically tunable liquid crystal and static metasurface structure, it realizes the collaborative perception of light field control and multi-dimensional information extraction at the micro-nano scale. In this case, one side of the liquid crystal cavity has a nanostructure, and the other side is a flat glass surface.
[0026] Furthermore, in one embodiment of this disclosure, the metasurface units inside the reconfigurable metachip are composed of a subwavelength-scale array of nanopillars, each of which can be freely designed in terms of its contour and topology to achieve local encoding of the target light field in four dimensions: space, angle, spectrum, and polarization.
[0027] Furthermore, in one embodiment of this disclosure, an initial set of nanopillar structure parameters specific to the target task can be designed based on prior information of the target task. This initial set serves as a template during chip manufacturing, enabling rapid task switching and adaptive operation through electro-hydraulic fine-tuning. For example, assuming the target task is a digit recognition task, dynamic weighting of different spectral channels can achieve a high robust recognition rate of the target digit under changing backgrounds; assuming the target task is angle reconstruction, a phase encoding structure that enhances angular resolution can be automatically selected, and spectral redundancy can be compressed, thereby achieving high-precision three-dimensional contour recognition. This hardware-level "task-aware" mechanism is difficult to achieve with traditional image sensors. Based on this, the control and scheduling unit can determine the first target structure of the reconfigurable metachip from the set of reconfigurable metachip structures through a second mapping relationship, according to the target task.
[0028] Furthermore, in one embodiment of this disclosure, the control and scheduling unit can determine the first target voltage signal corresponding to the target task from the voltage set through a first mapping relationship according to the target task, and send the first target voltage signal to the on-chip optical sensing unit to regulate the optical response characteristics of the reconfigurable metachip and realize task-related encoding.
[0029] Furthermore, in one embodiment of this disclosure, the on-chip signal preprocessing unit may include an image acquisition chip and an edge acceleration module. The method for acquiring an optical field compression feature value image and preprocessing it to obtain a target digital feature image may include: the image acquisition chip performing photoelectric conversion on the optical field compression feature value image to obtain an initial digital feature image; and the edge acceleration module preprocessing the initial digital feature image to obtain the target digital feature image.
[0030] In one embodiment of this disclosure, the image acquisition chip can be a built-in low-power image acquisition chip (such as a custom CMOS).
[0031] Furthermore, in one embodiment of this disclosure, the method by which the edge acceleration module preprocesses the initial digital feature image to obtain the target digital feature image may include: the edge acceleration module performing image reading, normalization, filtering, and enhancement on the initial digital feature image to obtain the target digital feature image.
[0032] Furthermore, in one embodiment of this disclosure, the control and scheduling unit 101 can determine a first target neural network model from the neural network model set through a third mapping relationship based on the target task. This allows the on-chip intelligent computing unit to load task-specific lightweight model weights, achieving an end-to-end data processing closed loop. The entire process can be driven by a task descriptor, managing the coordinated operation of each task through a unified interface, thereby improving the overall flexibility and resource utilization of the system. The neural network model set may include CNN and Transformer variants.
[0033] Furthermore, in one embodiment of this disclosure, the system further includes an adaptive adjustment unit 105; the adaptive adjustment unit 105 can be connected to the on-chip optical sensing unit 102 and the on-chip intelligent computing unit 104 respectively, wherein the adaptive adjustment unit is used to acquire task results and determine the corresponding second target voltage signal and the second target structure of the reconfigurable meta-chip, as well as the second target neural network model based on the task results.
[0034] In one embodiment of this disclosure, the method by which the adaptive adjustment unit 105 determines the corresponding second target voltage signal, the second target structure of the reconfigurable metachip, and the second target neural network model based on the task results may include: determining the corresponding second target voltage signal from the voltage set through a first mapping relationship based on the task results; determining the second target structure of the reconfigurable metachip from the structure set of the reconfigurable metachip through a second mapping relationship based on the task results; and determining the second target neural network model from the neural network model set through a third mapping relationship based on the task results.
[0035] Furthermore, in one embodiment of this disclosure, the aforementioned reconfigurable intelligent imaging chip system is suitable for rapid recognition tasks in fixed scenarios and can also adapt to perceptual changes in dynamic scenarios. The adaptive adjustment unit can monitor the distribution changes of the input image and the acquired task results in real time, dynamically adjusting the voltage signal, the target structure of the reconfigurable meta-chip, and the neural network model to form a dual closed-loop mechanism of "adaptive + self-feedback." This allows the reconfigurable intelligent imaging chip system to exhibit some characteristics of brain-like intelligence: adapting to new inputs without retraining when local scene changes, thus improving its robustness and versatility in practical deployments.
[0036] The reconfigurable intelligent imaging chip system disclosed herein includes a control and scheduling unit, an on-chip optical sensing unit, an on-chip signal preprocessing unit, and an on-chip intelligent computing unit. The control and scheduling unit is connected to both the on-chip optical sensing unit and the on-chip intelligent computing unit, and is used to acquire a target task, and based on the target task, determine a corresponding first target voltage signal, a first target structure of the reconfigurable meta-chip, and a first target neural network model. The on-chip optical sensing unit is connected to the control and scheduling unit, and is used to modulate the reconfigurable meta-chip of the first target structure using the first target voltage signal to perform in-situ modulation and compression encoding of a high-dimensional light field, obtaining a compressed light field feature image.
