    LC tunable filter

    Feb. 1, 1997
    The VS-RGB liquid-crystal tunable filter is electronically tunable in less than 1 ms with no moving parts or vibration. The filter switches between the three primary colors to generate the RGB color set (useful for NTSC display systems). This provides high-resolution sequential-color imaging with monochrome CCD cameras. The filter has an aperture of 20 or 35 mm, has wavelength range of 400 to 700 nm, transmits at least 30% of incoming light, and has a response time of 0.45 ms and reset time of l
