1. A METHOD OF PRODUCING AN AMBIENT LIGHT TRAPPING FILTER HAVING A PLURALITY OF SUBSTANTIALLY PARALLEL DEPTHWISE SPACED FILTER ELEMENTS OF GRID FORM IN PREDETERMINED REGISTRY, COMPRISING THE STEPS OF:
- APPLYING TO A TRANSPARENT BASE LAYER A LAMINATE CONSISTING OF A PLURALITY OF LAYERS OF PHOTO-SENSITIVE MATERIAL SEPARATED BY LAYERS OF NONPHOTO-SENSITIVE MATERIAL;
ALL OF SAID LAYERS BEING BONDED TOGETHER AND BEING PERMEABLE IN-SITU BY A PHOTO-DEVELOPING FLUID;
PLACING OVER AND IN CONTACT WITH SAID LAMINATE A MASK HAVING TRANSPARENT PORTIONS CORRESPONDING TO A PREDETERMINED GRID PATTERN WITH OPAQUE PORTIONS THEREBETWEEN;
EXPOSING SAID LAMINATE TO A SOURCE OF LIGHT PASSING THROUGH THE TRANSPARENT PORTIONS OF SAID MASK TO PRODUCE LATENT IMAGES OF CORRESPONDING GRID PATTERNS IN EACH OF SAID PHOTO-SENSITIVE LAYERS IN PREDETERMINED REGISTRY WITH EACH OTHER;
AND DEVELOPING SAID LATENT IMAGES INTO PERMANENT VISIBLE FOR, RETAINING ALL OF THE MATERIAL OF SAID LAYERS IN PLACE TO PRODUCE A FINAL LAMINATE OF SUBSTANTIALLY UNIFORM THICKNESS CONSTITUTING A TRANSPARENT PANEL BEARING BETWEEN ITS FACES A PLURALITY OF DEPTHWISE SPACED PATTERNS OF GRID MARKINGS IN PRECISE REGISTRY.
