Abstract
THERE ARE VARIOUS METHODS PRESENTLY IN USE FOR ACCURATE MEASUREMENT OF DISTANCES INVOLVING LASER TECHNOLOGY. THESE DEVICES, INTERFEROMETERS, USE COHERENT LIGHT WAVES TO INTERPRET DISTANCES. MEASUREMENT IS QUITE PRECISE; HOWEVER, THE UNIT IS COSTLY AND MUCH MORE PRECISE THAN MANY APPLICATIONS REQUIRE. THEY ARE ALSO BULKY, DIFFICULT TO IMPLEMENT, AND USUALLY DESIGNED FOR OPERATION IN A FIXED POSITION. THE DEVELOPMENT OF A MORE PRACTICAL AND SIGNIFICANTLY LESS EXPENSIVE MEASURING DEVICE USING LASER TECHNOLOGY IS AN OPPORTUNITY TO IMPROVE UPON THESE INTERFEROMETERS. OPTIMA PROPOSESA UNIT THAT INCORPORATES A LASER WHICH PRODUCES MODULATED LIGHT WAVES.THIS MODULATED LIGHT WOULD BE DIRECTED AT A TARGET OBJECT. THE OBJECT WOULD REFLECT THIS LIGHT BACK TO A BEAM SPLITTER, WHERE THE RETURNED MODULATION WOULD TRAVEL TO A PHOTOCELL. THE PHASE OF THE RETURNED LIGHT WOULD BE PROCESSED THROUGH A PHASE COMPARATOR. THE RESULT OF THIS PROCESS WOULD BE A DC VOLTAGE WHICH WOULD THEN BE DIGITIZED USING AN A/D CONVERTER AND THE DISTANCE DISPLAYED ON A LED OR LCD DISPLAY. A SIMPLE MICROPROCESSOR WOULD CONTROL DISPLAY FUNCTIONS, TEMPERATURE COMPENSATION, AND NORMALIZE ANY PHASE NON-LINEARITY.
