Development of Optical Space- Vision Instrumentation 960922

High visibility electronic analog instruments with the blackface lens, lighting up pointers, and back lit dials are used in increasing number for automotive instrumentation.Now, we have developed a new instrument called Optical Space-Vision Instrumentation incorporating the above electronic analog instrument with virtual image by double reflection mechanism. The purpose of this development is to reduce reading time through far-focus and to improve visibility through high contrast. As part of this instrumentation, we also developed a new pointer that uses fluorescent material without a light-emitting element. This paper describes the construction and the engineering technology associated with this instrumentation. According to our test results, this instrument has realized a shorter reading time and higher contrast.
