Abstract
A system for measuring spaces in a periodic matrix includes a plurality of light sources for simultaneously illuminating the matrix with light at a plurality of discrete locations. A plurality of linear photodiode arrays simultaneously receive the respective light/shadow images from the matrix at the discrete locations, and associated control and quantizer circuits produce signals representative of the spaces and areas therebetween. RETICON interface circuits are coupled, respectively, to the control and quantizer circuits for simultaneously converting the signals for each location into data values and transmitting the data values in parallel to respective RAMs. RAM interface control circuits are coupled, respectively, to the RAMs for sequentially addressing the respective RAMs for seriatim transfer of the data values to a computer.
