Avago faces the computer mouse to employ and push the small-scale laser navigation sensor
AvagoTechnologies (fit China's Hi-Tech) Announce, face the mouse application of the wired and wireless computer, introduce two new high-precision miniaturization laser navigation sensors. Adopt the intersection of Avago and the intersection of LaserStream and technology of patent, new navigation sensor these offer many kinds of abundant intact the intersection of lens and choice, it is simple to use that ADNS-7530/7550 navigation sensor of Avago can help the design engineer of the mouse to develop at the same time, can be in the mouse products of the work of accurate tracing of surface of many more kinds of different materials at the same time. Through the introduction of the new ADNS-7530/7550 sensor, Avago has further broken through the size that the design engineer of the mouse has faced for many years and limited the question, the navigation sensor of laser offers up to 30 inches (ips, inchespersecond) per second And the high-speed motion detection of 8g, chip Built-in: resonator and Integrated vertical cavity surface emission typ laser (VCSEL at the same time, Vertical-CavitySurfaceEmittingLaser) Can design devices used to count and minimise, in addition, these laser sensors use the characteristic of serial light beam and light interference to understand the surface feature accurately, let the mouse in the accurate tracking of many more kinds of different surfaces of material. Series ADNS-7550 of Avago are suitable for wired application such as PC wired mouse, trace ball and input device, ADNS-7530 series adopt and allocate the modal low power consumption framework of automatic power management, make it quite suitable for travelling and using wireless applications such as mouse and wireless input device,etc..
Avago obtains the serial surface picture through the optical way on the basis of optical guidance technical series ADNS-7530/7550, and determine moving direction and distance with mathematic calculation and include a picture acquisition system (IAS in ADNS-7530/7550, ImageAcquisitionSystem) ,A digital signal processor, and it is line type and serial to support four and have the interface (SPI) outside ,Among them IAS obtains the external miniature picture through lens and lighting system, then these pictures are dealt with through DSP to determine moving direction and distance. This framework design adopts LaserStream optical mouse technology of patent Avago, can offer the rigorous tracing result on surface of many kinds of different materials, especially on smooth surface such as smooth photographic paper, all black surfaces and sloping.
ADNS-7530/7550 offers three kinds of different lens choices at the same time, can help the design engineer not to need to change the basic plane structure of the Off-The-Shelf mouse while adopting and capsulating newly and designing, the lens choose to include miniaturization lens ADNS-6150, adjust lens ADNS-6160-001 and wide type to adjust lens ADNS-6170-002, these lens are chosen as the mouse manufacturer bringing the complete flexible degree of design, different design requirements of according with and resisting ESD interfering with, rearward compatibility and miniaturization mouse and designing etc..
ADNS-7530/7550 the intersection of laser sensor and encapsulated framework design, collocate upper the intersection of lens and fixed function, can simplify to the equipment movements on the p-c board of the mouse, the size is that the width of 16.2mm long * 10.1mm is * 3.96mm high, ADNS-7530/7550 laser module of Avago is quite suitable for the laser mouse of miniaturization to design, these new sensors mainly face OEM and retail market customer, integrate laser sensor and VCSEL in quite small single capsulation of space usage, bring mouse designing and simple and easy equipment of miniaturization.
