Description

ビームスプリッタ５１は、光トラップを形成するのに用いられる光の波長を選択的に反射し、他の波長を伝播させてビームレットの２つのストリームを形成する。したがって、図２および３に示されるように、ビームレットの第一のストリームは領域Ｃから対物レンズ１８の後ろの開口部１６の領域Ｂを通って進み、それにより全てのビームレットを後ろの開口部で効果的に重ねて光トラップ１００２および１００４を形成する。ビームレットの第二のストリームはビームスプリッタ５１によってモニタの方に反射されて、結像照明源（図示せず）の助けを借りて、リアルタイムで光学データストリームを提供するのに用いられる。ビームレットの第二のストリームは装置８を通過し、人間のモニタ６５によって目視６４ａされる。モニタ６５はコンピュータ６６とのインタフェースであってもよく、ビームレット３２の一つあるいはすべての位置を変更するようにシステムのパラメータをコンピュータに変更させる。
The beam splitter 51 selectively reflects the wavelength of light used to form the optical trap and propagates other wavelengths to form two streams of beamlets. Thus, as shown in FIGS. 2 and 3, the first stream of beamlets travels from region C through region B of the aperture 16 behind the objective lens 18, thereby causing all beamlets to pass through the rear aperture. The optical traps 1002 and 1004 are effectively overlapped with each other. The second stream of beamlets is reflected towards the monitor by beam splitter 51 and is used to provide an optical data stream in real time with the help of an imaging illumination source (not shown). The second stream of beamlets passes through the device 8 and is viewed 64a by a human monitor 65. The monitor 65 may be an interface to the computer 66 and causes the computer to change system parameters to change one or all positions of the beamlet 32.
