Title:
FIELD SEQUENTIAL TYPE COLOR HEADUP DISPLAY SYSTEM
Document Type and Number:
Japanese Patent JPH0667117
Kind Code:
A
Abstract:

PURPOSE: To make possible control and correction by compact, programmable software.

CONSTITUTION: This system is equipped with an image generating means 11 which has at least two light sources differing in wavelength, a polarizing means equipped with a color selective polarization filter 16 having a 1st and a 2nd absorption axis (1st and 2nd absorption axes pass linear polarized light of 1st and 2nd colors), an annular polarizing means 18 which selectively transmit a light of a color limited depending upon a quantity by which a radiant light is optically decelerated, a variable optical decelerating means 20, a control means 24 which controls the quantity of optical deceleration imposed on the transmitted light, an image coupling means 28 and an image parallelizing means 26 which superpose a generated image on a scene that an observer sees, and a holograph means 38 which allows the scene 34 and generated image to be both seen through the image coupling means 28 by an optical wavelength increasing means 36.
