Measurable speckle gradation Hadamard single-pixel imaging
《Chinese Optics Letters》2024年第3期31-35,共5页周立宇 白艳锋 付芹 朱孝辉 黄贤伟 邹璇彭凡 傅喜泉 
supported by the National Natural Science Foundation of China(Nos.62101187,61971184,and 62001162);the Hunan Provincial Natural Science Foundation(No.2022JJ40091);the Fundamental Research Funds for the Central Universities(No.531118010757)。
The array spatial light field is an effective means for improving imaging speed in single-pixel imaging.However,distinguishing the intensity values of each sub-light field in the array spatial light field requires the...

Real-time gradation-expressible amplitude-modulationtype electroholography based on binary-weighted computer-generated hologram被引量:1
《Chinese Optics Letters》2021年第11期8-15,共8页Ren Noguchi Kohei Suzuki Yoshiki Moriguchi Minoru Oikawa Yuichiro Mori Takashi Kakue Tomoyoshi Shimobaba Tomoyoshi Ito Naoki Takada 
This work was partially supported by the Japan Society for the Promotion of Science(JSPS)KAKENHI(No.21K11996);I-O DATA Foundation.
In amplitude-modulation-type electroholography, the binary-weighted computer-generated hologram(BW-CGH) facilitates the gradation-expressible reconstruction of three-dimensional(3 D) objects. To realize real-time grad...
