We report about the implementation of the liquid crystal on silicon (LCOS) microdisplay with 1920 by 1080 resolution and 720 Hz frame rate. The driving solution is FPGA-based. The input signal is converted from the ultrahigh-resolution HDMI 2.0 signal into HD frames, which follow with the specified 720 Hz frame rate. Alternatively the signal is generated directly on the FPGA with built-in pattern generator. The display is showing switching times below 1.5 ms for the selected working temperature. The bit depth of the addressed image achieves 8 bit within each frame. The microdisplay is used in the fringe projection-based 3D sensing system, implemented by Fraunhofer IOF.
We present the implementation results of the liquid-crystal on silicon phase-only spatial light modulator, which features high resolution, high reflectivity and improved damage threshold. The data on diffraction efficiency, flatness and temporal noises is presented as well.
We report about the implementation of the 10Megapixel phase-only liquid crystal on silicon spatial light modulator for the visible and short-wave infrared spectral bands. The pixel pitch of the SLM is less than 4 micron. Experimental data for diffraction efficiency, reflectivity, phase response, flatness and temporal noises is provided.
Phase contrast and interference microscopes are widely used for microbiological and biomedical research. However
most of them can't give high precision quantitative estimation of cell volume and morphology due to modest resolution.
We propose scheme based on a modified laser Linnik microinterferometer providing high both phase and spatial
resolutions. Red blood cell volume is calculated using integration of phase height distribution; limits of integration are
determined by Canny edge detection procedure. Experimental volume estimation fits well to volume data obtained with
