There is a need to provide a photo-optical digitizer system to ascertain quickly and accurately, the information required. Many quantitative measurements must also be recorded, compared, stored, and computed in real time. The best feasible solution is a semi-automatic system with an open-end output capability, able to digitize the information. The L-W International 110-C Photo-Optical Digitizer System, the "Informer," could solve the dilema. The system will accept an image from projectors with various a-perture formats, television monitors, and hard copy. The Digitizer provides for lengths, areas, angles, frame count, and other various features. After digitizing, data can be transmitted to computer peripherals and major computer systems. The "Informer" has a standard EIA-RS232C or Bit Parallel output interface or optional special interfaces.
