| 英文摘要 | A sinusoidal phase-modulating (spm) laser diode (ld) interferometer for real-time surface profile measurement is proposed and its principle is analyzed. the phase signal of the surface profile is detected from the sinusoidal phase-modulating interference signal using a real-time phase detection circuit. for 60 x 60 measurement points of the surface profile, the measuring time is 10 ins. a root mean square (rms) measurement repeatability of 3.93 nm is realized, and the measurement resolution reaches 0.19 nm. |
