Patent number: 11934027Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.Type: GrantFiled: June 21, 2022Date of Patent: March 19, 2024Assignee: TDK TAIWAN CORP.Inventors: Chao-Chang Hu, Chih-Wei Weng, Chia-Che Wu, Chien-Yu Kao, Hsiao-Hsin Hu, He-Ling Chang, Chao-Hsi Wang, Chen-Hsien Fan, Che-Wei Chang, Mao-Gen Jian, Sung-Mao Tsai, Wei-Jhe Shen, Yung-Ping Yang, Sin-Hong Lin, Tzu-Yu Chang, Sin-Jhong Song, Shang-Yu Hsu, Meng-Ting Lin, Shih-Wei Hung, Yu-Huai Liao, Mao-Kuo Hsu, Hsueh-Ju Lu, Ching-Chieh Huang, Chih-Wen Chiang, Yu-Chiao Lo, Ying-Jen Wang, Shu-Shan Chen, Che-Hsiang Chiu

Patent number: 11933969Abstract: An optical engine module including at least two laser sources, collimators, a light combining lens group, an aperture, a beam shaping lens group, a MEMS scanning module, and a beam expansion lens group is provided. The at least two laser sources respectively generate at least two laser beams with different wavelengths. The collimators respectively collimate the at least two laser beams to generate at least two collimated beams. The light combining lens group combines the at least two collimated beams into a combined beam. The aperture filters stray beams of the combined beam. The beam shaping lens group shapes the combined beam to generate a shaped beam with a perfect circle. The MEMS scanning module reflects the shaped beam and scans in horizontal and vertical directions to form a scanning beam. The beam expansion lens group expands the scanning beam into an expanded beam having a predetermined area.Type: GrantFiled: May 28, 2021Date of Patent: March 19, 2024Assignee: MEGA1 COMPANY LTD.Inventors: Makoto Masuda, Han-Chiang Wu, Shan-Ling Yeh, Tzu-Chieh Lien
