The patent covers the use of a computer-designed diffraction grating, a type of hologram that takes a single beam and breaks it up into an array of beams, each one of which forms an optical trap for particles of micron or nanometer dimensions.

• 此专利涵盖了电脑设计的绕射光栅，以及可将单一光束分散成阵列光束的雷射全像术，其中每道光束都会形成光阱，可捕捉微米或奈米大小的粒子。
