35-MM QUADRICAMERA

Abstract

A QUADRICAMERA SYSTEM FOR AERIAL NON-METRIC PHOTOGRAPHY WAS DESIGNED AROUND THE ROBOT 35-MM CAMERA SYSTEM. THE QUADRICAMERA ALLOWS BOTH MULTIBAND AND MULTIEMULSION TECHNIQUES AND WAS DESIGNED FOR MULTISPECTRAL INVENTORY, RECONAISSANCE AND NON-PHOTOGRAMMETRIC STUDIES OF SHORELINES, MARSHLANDS, ESTUARIES AND HARBORS. STANDARD PHOTOGRAPHIC EQUIPMENT ALLOWS FOR INEXPENSIVE CONSTRUCTION, AND THE 35-MM FILM FORMAT ALLOWS FOR INEXPENSIVE OPERATION. COMPACT DESIGN ALLOWS FOR USE FROM LIGHT AIRCARFT, ALSO REDUCING OPERATION COSTS. THE ROBOT QUADRICAMERA SYSTEM IS COMPLETELY MECHANICAL IN OPERATION AND REQUIRES NO ELECTRIC POWER SUPPLY. INTERNAL SPRING-DRIVE MOTORS WITHIN THE CAMERA PROVIDE FOR SHUTTER COCKING AND FILM ADVANCE, AND 50 EXPOSURES ARE POSSIBLE EFORE REWINDING. A SPECIAL MECHANICAL SHUTTER-RELEASE SYSTEM, DESIGNED FOR THE QUADRICAMERA, ALLOWS SIMULTANEOUS TRIPPING OF ALL FOUR CAMERAS. /AUTHOR/
