Multispectral sensor array for ranging and imaging systems
The patent US12072237B2 describes a sophisticated ranging and imaging system that integrates multiple sensor technologies to capture both depth and ambient light information. The system features a sensor array composed of various sensor channels, including LIDAR and ambient-light sensors, organized into multiple rows. Each ambient-light sensor channel is equipped with a channel input aperture, a photosensor, and a channel-specific optical filter designed to selectively transmit light based on specific properties. A bulk optic module is positioned in front of the sensor array to direct light, enabling the formation of an image that combines ambient-light intensity and depth data from the respective sensor channels.
The claims further detail the arrangement and functionality of the sensor channels, emphasizing their lateral displacement in the focal plane of the bulk optic module and their non-overlapping fields of view. The system is designed to operate as a single integrated circuit, with a controller to generate image data. Specific configurations of the ambient-light sensor channels are highlighted, including sensitivity to different portions of the visible spectrum (red, green, and blue light). Additionally, the patent outlines the use of channel-specific micro-optic elements that enhance the optical performance of the sensors, compensating for factors such as chromatic aberration and curvature in the focal plane. The inclusion of single-photon avalanche diodes (SPADs) in the sensor channels further enhances the system's sensitivity and performance in capturing detailed imaging data.
