Text version of the page

LDDM Technology vs. Michelson Interferometer Technology LDDM technology Michelson interferometer LDDM Advantage ? Higher performance, (Single frequency) ? Lower cost 1. Latest Electro Optics & Radio Frequency technology with many patents Interferometer technology 2. 2-frequency, FM & heterodyne Single-frequency, AM & homodyne ? Higher Signal to Noise Ratio (consider FM Radio versus AM Radio) ? Higher signal quality ? Less interference 3. Frequency locked Frequency locked ? Frequency stable 4. Single aperture Dual-aperture ? Smaller retroreflector capability ? Flat-mirror target capability ? Larger beam diameter possible ? Fewer Optical Components 4a. Small laser head Large laser head ? Compact ? Easily mount on machine ? No need for a tripod ? Smaller carrying case 4b. Small retroreflector Large retroreflector ? Reduces the size of all optical components ? More compact 5. 2 elements to align 3 elements to align ? Easy Faster setup and alignment ? Fewer Separate Optical Components ? More efficiency ? Less training 6. Low laser output power High laser output power ? Eye Safe 7. Long range, up to 100 m Short range ? Long range without increasing laser power 8. Fast, 5 m/sec Slow, 1 m/sec ? Good for high speed linear motor machine 9. Digital electronics ? ? Large Dynamic Range 1
