Optical navigation sensor technology works by taking thousands of digital pictures per second with a resolution of up to 800 counts per inch to determine the movement of the on-screen cursor.
Optical mice eliminate the need for a mouse pad and offer more precise pointing and movement than mechanical mice.
And because optical mice have no ball or cavity, no cleaning is necessary, making them more reliable and longer lasting.
The Agilent ADNS-2051 sensor contains an image acquisition system, a digital signal processor, a two-channel quadrature output and a two- wire serial port.
The ADNS-2051 is designed to be used with the Agilent HDNS-2100 lens and HDNS-2200 clip with HLMP-ED80 LED.
Together, these parts comprise the complete, compact mouse sensor solution.
Operation of the navigation sensor starts when the user moves his optical mouse.
Slight or rapid movement of the mouse triggers the sensor's image acquisition system to acquire microscopic surface images via the lens and illumination system.
These images are processed by the DSP to determine the direction and distance of motion.
The DSP generates position values that are converted into two-channel quadrature signals.
The computer then accesses the motion information either through the quadrature output or two-wire serial port, directing the precise position of the on-screen cursor.
The Agilent ADNS-2051 sensor is programmable offering 400 or 800count/in resolution, a motion rate of 14in/s and frame rates up to 2300frame/s.
It operates on a single 5V power supply and features on-chip LED drive and power conservation mode during times of no movement.
The Agilent ADNS-2051 optical navigation sensor is available in production Volumes in a 16-pin staggered DIP. Request a free brochure from Avago Technologies ...
