An intra-oral digital impression scanner having a window （9）limiting an acquisition range includes a three-color LED light source module group(1),a micro lens array board (2),a collimating lens group(3), a gray-coding grating slab (4), an optical deflector(5),a projection lens group (6), a first reflector (71), a second reflector (72) and a third reflector (73) which are positioned in parallel and whose reflection surfaces are opposite, and a camera (8),along the direction of a light path in sequence. The intra-oral digital impression scanner can achieve a direct scan inside a human's mouth, and acquire a real-time new digital impression of three-dimensional surface topography of teeth and soft tissues. It can satisfy dentists' and dental physicians' desire of quick, accurate acquisition for dental impression.

Displacement sensor for measuring length by using multiple Hall sensor chips

Номер: CN116336923A
Автор: GONG XIANGDONG, SHAO CHENGYE, LI PENG
Принадлежит:

The invention relates to a device for measuring displacement by utilizing a plurality of Hall sensor chips and a magnet, the measurement principle is that the position of a target magnet is determined through the voltage of the plurality of Hall sensor chips by utilizing the Hall effect, as shown in the figure 1 of the specification, the device consists of two parts, namely a magnet A1 mounted on a moving object and a magnet A2 mounted on a moving object, one is a circuit board A on which a plurality of Hall sensing devices are mounted, the other one is a circuit board A2 on which a plurality of Hall sensing devices are mounted, the circuit board is fixed below the magnet, and a plurality of Hall sensor chips are mounted on the circuit board at equal intervals. The accurate position of the current magnet is determined by the induced voltage of the three chips, and the left sensor and the right sensor are used for assisting in judging whether the current position of the central sensor deviates ...
