interferometer (Single frequency)
LDDM Advantage1.
Latest Electro Optics &
Radio Frequency technology
with many patents Interferometer technology · Higher performance, · Lower cost 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
