20150092099 | FAST FOCUSING METHOD AND DEVICE FOR MULTI-SPECTRAL IMAGING - Fast focusing methods and devices for multi-spectral imaging are disclosed. The method comprising selecting one of a plurality of imaging channel as a reference channel, adjusting rotation positions of a stepper motor, calculating focus measures corresponding to all rotation positions of the stepper motor, and obtaining a first distribution curve; in each of the other imaging channels, selecting at least three rotation positions of the stepper motor, matching focus measures at the selected rotation positions with the first distribution curve to obtain a second distribution curve and a offset value between the first distribution curve and the second distribution curve, and calculating a clear focusing position of the imaging channel to be focused according to the offset value; performing a fine-tuning focusing, and thereby obtaining a more precise clear focusing position. A fast focusing for multi-spectral imaging and obtain clear multi-spectral images is obtained. | 04-02-2015 |
20140205795 | THREE DIMENSIONAL NEGATIVE POISSON'S RATIO SPACER KNITTED FABRIC AND METHOD FOR MAKING THE SAME - This present application relates to a three dimensional negative Poisson's ratio spacer knitted fabric and a method for making the same; the fabric includes a first surface layer fabric, a second surface layer fabric, and a spacer yarn layer connecting the first surface layer fabric with the second surface layer fabric, both the first surface layer fabric and the second surface layer fabric are bi-dimensional structures having the negative Poisson's ratio effects; the method is to compress and/or stretch a three dimensional mesh spacer knitted base fabric along one or two plane directions to form a structures having the negative Poisson's ratio effects.
