Patent number: 11953756Abstract: An optical system (100), sequentially comprising from an object side to an image side: a first lens (L1) having positive refractive power, an object-side surface (S1) of the first lens (L1) being a convex surface at the circumference; a second lens (L2), a third lens (13), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6), and a seventh lens (L7) having refractive power; and an eighth lens (L8) having negative refractive power. An image-side surface (S14) of the seventh lens (L7) is a concave surface at the optical axis. In addition, the optical system (100) satisfies 1<TTL/<2.5, wherein TTL is the distance between the object-side surface (S1) of the first lens (L1) and an imaging surface (S19) of the optical system (100) on the optical axis. The optical system (100) further comprises a diaphragm (STO), and L is the effective aperture diameter of the diaphragm (STO).Type: GrantFiled: August 15, 2019Date of Patent: April 9, 2024Assignee: Jiangxi OFILM Optical Co., Ltd.Inventors: Wenyan Zhang, Binbin Liu, Hairong Zou

Patent number: 11937980Abstract: A multi-row ultrasonic imaging apparatus and an ultrasonic imaging instrument are disclosed. The multi-row ultrasonic imaging apparatus includes a housing, and a first ultrasonic transducer, a second ultrasonic transducer, and an adjustment mechanism that are installed in the housing. Ultrasonic waves emitted by the first ultrasonic transducer and the second ultrasonic transducer can intersect to form a confocal point. At least one of the first ultrasonic transducer and the second ultrasonic transducer is connected to the adjustment mechanism to move relative to the housing under the action of the adjustment mechanism, so as to adjust the position of the confocal point.Type: GrantFiled: September 15, 2021Date of Patent: March 26, 2024Assignee: SHENZHEN INSTITUTES OF ADVANCED TECHNOLOGYInventors: Weibao Qiu, Min Su, Zhiqiang Zhang, Hairong Zheng
