Reflective Optical Programmble Encoder -Blue Light Led

Technology presented from red led to optical blue led goes in a small size and various applications like position, speed, velocity, displacements to achieve high resolutions from native CPR to achieve this BLUE led is the ladder for all encoder manufacture to cut the cost of manufacturing and materials .The life of all applications make easy due to advantages like o improved signal quality. Use of this technology gives low optical crosstalk .Interpolation programming of chip signal for easy higher resolution are getting at low cost compared to optical encoder. Mechanical rugged structure gives space benefit in a various applications Keywords - Blue led, interpolation, encoder, signal
