Continuous Phase Plate Structuring by Multi-Aperture Atmospheric Pressure Plasma Processing [PDF]
Micromachines, 2019 A multi-aperture atmospheric pressure plasma processing (APPP) method was proposed to structure the continuous phase plate (CPP). The APPP system was presented and removal investigation showed the removal function of APPP was of a high repeatability and ...

A multi-aperture encoding scheme for increased SNR in photoacoustic Imaging. [PDF]
Photoacoustics, 2023 Photoacoustic imaging creates light-induced ultrasonic signals to provide valuable information on internal body structures and tissue morphology non-invasively. A multi-aperture photoacoustic imaging (MP-PAI) system is an improvement over conventional photoacoustic imaging (PAI) systems in terms of resolution, contrast, and field of view. Previously, a

A Novel Multi-Aperture Based Sun Sensor Based on a Fast Multi-Point MEANSHIFT (FMMS) Algorithm
Sensors, 2011 With the current increased widespread interest in the development and applications of micro/nanosatellites, it was found that we needed to design a small high accuracy satellite attitude determination system, because the star trackers widely used in ...

Multi-aperture imaging for flat cameras [PDF]
Optics Letters, 2020 Imaging with high angular resolution requires large apertures and long focal lengths. This has prevented the integration of telephoto lenses into thin devices such as modern mobile phones. We report a camera module employing multiple rotated rectangular apertures and folding of the optical system into the plane of the camera, enabling an order-of ...

Statistical Model of Digital Coherent Combining Efficiency in Multi-aperture Receivers
Guangtongxin yanjiu, 2022 In order to mitigate the performance fading of Free-Space Optical (FSO) communication system caused by atmospheric turbulence, a multi-aperture receiving scheme based on digital coherent beam combining is used.

Multi-aperture foveated imaging [PDF]
Optics Letters, 2016 Foveated imaging, such as that evolved by biological systems to provide high angular resolution with a reduced space-bandwidth product, also offers advantages for man-made task-specific imaging. Foveated imaging systems using exclusively optical distortion are complex, bulky, and high cost, however.
