摘要： The present invention concerns an optical system for spatiotemporally shaping the wavefront of the electric field of a light beam (1) to be projected into a target volume (5), where the propagation axis is axis z, to create 3D patterned illumination in the target volume (5), comprising a pulsed laser source, configured to have an illumination pattern whose transversal surface at the target volume being superior to the diffraction limit of the optical system, at least one intermediate optical element (4) which is a dispersive grating for performing temporal focusing of the light beam (1), located, on the propagation axis (z), where an image of the illumination pattern is formed, for modulating the phase and/or the amplitude of the electric field of the light beam, and a second optical element (3) which is a spatial light modulator for modulating the phase of the electric field of the input light beam, and for realizing spatiotemporal multiplexing to create 3D patterned illumination in the target volume (5) by replicating the illumination pattern, so as to have several replicated illumination patterns in the target volume (5), and controlling the position with transversal coordinates X, Y and axial coordinate Z of each replicated illumination pattern in the target volume (5).

摘要： A set of first signal light and reference light with a phase difference of almost 0 degree, a set of second signal light and reference light with a phase difference of almost 180 degrees, a set of third signal light and reference light with a phase difference of almost 90 degrees, and a set of fourth signal light and reference light with a phase difference of almost 270 degrees are generated. A first differential signal as a difference between a first light-receiving signal obtained by a first light-receiving element and a second light-receiving signal obtained by a second light-receiving element is calculated, and a second differential signal as a difference between a third light-receiving signal obtained by a third light-receiving element and a fourth light-receiving signal obtained by a fourth light-receiving element is calculated. The first differential signal and the second differential signal are supplied to respective FIR filters. An equalization error is formed from output signals from the FIR filters. Tap coefficients for the FIR filters are controlled to minimize the equalization error.

摘要： A protective member protects an obj ective lens. The protective member includes an insertion opening through which an objective lens is configured to be inserted and a main body configured to cover the inserted objective lens. The main body includes a side wall portion connected to the insertion opening and a bottom portion connected to the side wall portion as well as facing the insertion opening, and covers the inserted objective lens with the side wall portion and the bottom portion. The protective member further includes a liquid disposed inside the main body, a sealing film body for sealing the insertion opening and a window arranged in the bottom portion of the main body, through which light transmits. The protective member can simplify the work.
