摘要： An auto-focus system employing a tunable liquid crystal lens is provided that collects images at different optical power values as the liquid crystal molecules are excited between a ground state and a maximum optical power state tracking image focus scores. An image is acquired at a desired optical power value less than maximum optical power established with the liquid crystal molecules closer a fully excited state than the maximum optical power state having the same image focus score. This drive signal employed during image acquisition uses more power than was used to achieve the same optical power value during the auto-focus scan, while actively driving the liquid crystal molecules is fast. A pause due to image transfer/processing delays after acquisition is employed to allow slow relaxation of the liquid crystal molecules back to the ground state in preparation for a subsequent focus search.

摘要： A tunable filter array comprises a serial of tunable filters each has an input optical port and at least two output optical ports. All of the tunable filters commonly share a polarization conditioning optics, a polarization selective beam routing optics, a wavelength selective beam spatial separation/combination optics and a polarization controlling element array. The serial tunable filters are packaged by vertically stacking multiple sets of the input and output optical ports. The wavelength dependent beam separation/combination optics disperses an input optical beam into a two dimensional array of beam spots to focus on the two dimensional polarization control element array for controlling the polarization states of each of the beam spots. The polarization selective beam routing optics selectively routes the reflected beam from the wavelength dependent beam separation/combination optics to the output optical ports according to the polarization states of a wavelength segment corresponding to the beam spots.
