Abstract: A laser beam steering apparatus includes a beam steering cell with an adjustable shape, with the cell having opposing Fabry-Perot filters, and a steering mechanism coupled to the cell to adjust its shape so that the direction of a laser beam emitted from the cell is changed in response to a change in the cell shape.

Abstract: The present invention provides a device for trapping or stretching a microscopic substance comprising (a) a light source; (b) an acousto-optic modulator (AOM); (c)a beam-expander; (d) an object lens; and (e) an incoherent light source. The present invention further provides a method for trapping or stretching a microscopic substance comprising (a) providing a focused laser beam to form a focal spot and (b) scanning a plurality of points on said microscopic substance by said focal spot by way of the AOM.

Abstract: The present invention provides a device for trapping or stretching a microscopic substance comprising (a) a light source for irradiating laser beam; (b) an acousto-optic modulator (AOM) for regulating the direction of said laser beam irradiating from said light source; (c) a beam-expander for expanding and collimating the light beam emitting from said AOM; (d) an object lens for focusing the laser beam passing through said beam-expander; and (e) an incoherent light source for imaging said microscopic substance. The present invention further provides a method for trapping or stretching a microscopic substance comprising (a) providing a focused laser beam to form a focal spot and (b) scanning a plurality of points on said microscopic substance by said focal spot by way of the AOM.

Abstract: The present invention provides a method and device for simultaneous optical trapping, stretching, and measurement of morphological deformation of a micro-particle in real-time. Using the setup of the present invention, the deformability of a living cell can be obtained in real-time by measuring the variation in coupling efficiency with optical power of light coupled from one single-mode fiber to the other through the lensing effect of the trapped-and-stretched micro-particle.

Abstract: A system and method for analyzing a biochip are provided. Wherein, a first modulator circuit outputs a first modulated signal with a first frequency. A first light source module output a first light beam based on the first modulated signal. A first optical signal is generated after the first light beam being emitted onto the biochip. An optical sensing module sense the first optical signal and outputting a first sensing signal. A first filter circuit filters the first sensing signal and outputting a first portion sensing signal. A first demodulator circuit demodulates the first portion sensing signal and outputting a first demodulated signal. An analog to digital converter convert the first demodulated signal to a first digital signal. A signal display module receives and display the first digital signal.
