  • Method and apparatus for improving signal to noise ratio of an aerial image monitor
    Patent number: 6515272
    Abstract: In an image monitoring apparatus, a pulsed-laser signal is modulated at a chosen frequency. The modulated signal is provided to an optical imaging system, the output signal is detected by an aerial image detector, and the signal from the aerial image detector is in turn amplified only at the chosen frequency. The apparatus includes an optical chopper for modulating the pulsed-laser signal, and a lock-in amplifier for amplifying the signal from the aerial image detector.
