Read Abstract +

We present a synthesized sub-ps dual-wavelength laser source for digital holographic interferometry with a wide reconstruction range. The developed laser source generates two spectrally separated parts within one pulse. The sub-ps pulse duration desensitizes the holographic setup to environmental impacts. A center wavelength distance of only 12 nm with a high contrast was demonstrated by spectral shaping of the 50 nm broad seed spectrum of a CPA Ti:sapphire laser system centered at 800 nm. Time-resolved two-wavelength contouring requires the simultaneous and separable recording of two holograms. In general, a single CCD-camera is applied, and the spectral separation is realized by different reference wave tilts, which requires ambitious interferometric setups. Contrary to this, we introduce two CCD-cameras for digital holographic recording, thus essentially simplifying the interferometric setup by the need of only one propagation direction of the reference wave. To separate the holograms for the simultaneous recording process, a Mach-Zehnder interferometer was extended by a polarization encoding sequence. To study our approach of time-resolved digital holographic two-wavelength contouring, an adaptive fluidic PDMS-lens with integrated piezoelectric actuator served as test object. The PDMS-lens consists of an oil-filled lens chamber and a pump actuator. If a voltage is applied to the piezoelectric bending actuator the fluid is pumped into the lens chamber which causes a curvature change of the 60-μm thick lens membrane and thus a shift of the focal length. The dynamic behavior of the PDMS-lens, driven at a frequency of 1 Hz, was investigated at a frame rate of 410 frames per second. The measured temporal change of the lens focal length between 98 and 44 mm followed the modulation of the piezoelectric voltage with a 30 V peak-to-peak amplitude. Due to the performed time-resolved two wavelength contouring, we are able to extract the optical path length differences between center and perimeter of the lens. From the calculated phase difference maps we estimated large optical path differences of larger than 10 μm, corresponding to more than 15 times of the source wavelength.

Deformation measurements of high-speed MEMS with sub-picosecond pulses using combined digital holographic two-wavelength contouring and single phase reconstruction

Read Abstract +

Circular and rectangular MEMS optical scanners operating at a resonance frequencies close to 1 kHz are investigated by single-pulse digital holographic two-wavelength contouring. Coverage of the range interesting for shape measurements of micro mechanical applications like optical scanning mirrors between 10 - 100 μm using only one laser source is a challenging task. For this purpose, a dual-wavelength laser source was developed that generates two 12 nm and 34 nm separated sub-picosecond pulses around 790 nm. A Twyman-Green interferometer was extended by a polarization encoding sequence to separate the interferograms for the recording process. The two holograms were captured simultaneously introducing two CMOS-cameras in the interferometer setup. The phase difference information of the object within the synthetic wavelength of 40 μm was unambiguously generated and the 3D-shape calculated. To reliably measure the surface deformation of the oscillating mirrors the evaluation of the single phase images is sufficient. The resulting deformation of the mirrors based on the reconstructed single phase from the holograms was captured at a wavelength of λ = 783 nm. The deduced rms-values of the surface shape of the oscillating mirrors at maximum load are only ~50 nm, corresponding to a surface flatness of better than λ/10. This is an excellent result, keeping in mind that the mirror plates of the optical scanners are only ~50 μm thick. These detail information from one interferogram are combined with the coarse shape information deduced from the phase difference map of the two interferograms captured at different wavelengths. Using two-wavelength contouring only for extracting the linear slope of the mirror and combining this with the detail information of the single phase images yields a combined reconstruction. This provides a much more realistic picture of the virtually vanishing deformations of the MEMS optical scanners operated at its resonance. We are not aware of any other method that could provide equally detailed information on such a MEMS structure while simultaneously capturing such a large amplitude of the dynamics.
