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.
