Patent number: 11073477Abstract: An epi-cone shell light-sheet super-resolution system and an epi-fluorescence microscope are provided. The epi-cone shell light-sheet super-resolution system includes a light-emitting element, a lens set, and an objective lens. After passing through the lens set, the excitation light emitted by the light-emitting element is refracted into ring-shaped light and focused on the objective-lens back-focal plane. The objective lens focuses the ring-shaped light to form a ring-shaped light cone which is then focused on the sample position. The ring-shaped light cone has a fixed thickness. In addition, the same objective lens is used for both excitation and imaging, thus achieving an epi-fluorescence microscope.Type: GrantFiled: August 29, 2019Date of Patent: July 27, 2021Assignee: National Tsing Hua UniversityInventors: Ann-Shyn Chiang, Li-An Chu, Wei-Kun Chang, Yen-Yin Lin

Publication number: 20160270378Abstract: A system for classifying tiny insects includes a cultivation tank, a detecting container, a detector, a gathering device, and a control unit. The cultivation tank is connected to the detecting container, so that the hatched tiny insects can enter the detecting area of the detecting container from the cultivation tank. The detector is used for detecting the characteristics of the tiny insects in the detecting area, and then the control unit controls the switching unit of the gathering device to switch the gathering containers for gathering the tiny insects according to the detecting results. The system of the present invention is capable of automatically classifying the tiny insects and then gathering them to different gathering containers according to their characteristics, so as to decrease the man power and time necessary for factitious classification.Type: ApplicationFiled: June 2, 2016Publication date: September 22, 2016Inventors: RONG-SHUN CHEN, HUNG-YIN TSAI, CHIEN-HUNG LIN, HONG HOCHENG, WEI-LEUN FANG, ANN-SHYN CHIANG, YU-CHING LIN, JHIH-SHUN YANG, YU-CHENG WU, LI-AN CHU, CHIA-LIN WU

Patent number: 8985056Abstract: A detecting platform for holding a tiny insect includes a main body forming a containing space, which passes through the main body and is surrounded by side walls of the main body. A first side wall and a second side wall of the side walls are opposite to each other, and the area of the second side wall is smaller than that of the first side wall. The main body forms a first opening and a second opening passing through the first side wall and the second side wall respectively for the tiny insects entering and leaving the containing space. A bottom plate covers a first through surface of the containing space to form a bottom surface and a detecting area is configured thereon to holding the tiny insects. Accordingly, the tiny insects can stay on the detecting area so as to detect the characteristics of the tiny insects expediently.Type: GrantFiled: March 13, 2012Date of Patent: March 24, 2015Assignee: National Tsing Hua UniversityInventors: Rong-Shun Chen, Jhih-Shun Yang, Yu-Ching Lin, Hung-Yin Tsai, Chien-Hung Lin, Hong Hocheng, Li-An Chu

Patent number: 8755571Abstract: An image method for classifying insects includes the following steps: obtaining detecting images of the insects in a detecting area; obtaining a first foreground image related to the insects by background subtraction; extracting the saturation from the first foreground image and eliminating the non-characteristic objects therein to obtain a second foreground image; extracting the characteristics related to the insects from the second foreground image according to a threshold; and, determining the classifications or the sexes of the insects according to the characteristics. Accordingly, the image method for classifying insects can be used for automatically classifying the insects so as to save the manpower and time.Type: GrantFiled: March 13, 2012Date of Patent: June 17, 2014Assignee: National Tsing Hua UniversityInventors: Hung-Yin Tsai, Yu-Ching Lin, Yu-Cheng Wu, Rong-Shun Chen, Hong Hocheng, Li-An Chu
