摘要: Methods and apparatus directed to using modulation substantially improve detection limits in optical imaging, the performance of various imaging systems. Such is achieved a modulated light source (40), frequency reference (42), detector (10), demodulator (46). The may comprise emitting an inherently output; or, this separate modulator continuous wave, modulated, or pulsed configured impose output source. for are also disclosed.
