Embodiment Construction
[0046] The present invention will be described below in conjunction with the accompanying drawings, but the present invention is not limited thereto.
[0047] Such as figure 1Shown is a structural schematic diagram of a wave plate group design method for compensating for any optical phase delay applied to a laser scanning confocal microscope system according to an embodiment of the present invention. The system of this embodiment includes: 1. a laser; 2. a linear polarizer ; 3, total reflection mirror; 4, half-wave plate; 5, quarter-wave plate; 6, dichroic mirror; 7, objective lens; 8, sample cell; 9, photodetector. The light wave output by the laser 1 is modulated into a linearly polarized light by the linear polarizer 2, and is incident on the half-wave plate 4 and the dichroic mirror 6 after passing through the total reflection mirror 3, and then modulated by the quarter-wave plate 5 from the objective lens 7 Arriving at the sample cell 8, the sample in the sample cell 8 i...

The invention discloses a wave plate group design method for compensating any optical phase delay. The method comprises the following steps of: 1) placing a wave plate group at the front end or the rear end of the optical path of an optical system to be compensated in optical phase delay; 2) establishing a Cartesian coordinate system by using the optical system to be compensated in optical phase delay as a reference and the fast axis direction of the optical system as a horizontal axis; 3) successively subjecting corresponding Jones matrixes to left multiplication to obtain a wave plate group-modulated Jones matrix of the optical system; 4) successively subjecting corresponding Jones vectors to left multiplication to obtain the Jones vector of an emitted optical wave; 5) comparing the modulated Jones vector of the emitted optical wave with a Jones vector corresponding to a required emitted optical wave polarization state, and calculating an intersection angles between respective wave plates in the wave plate group required to be adjusted and the horizontal axis of the reference coordinate system; 6) according to the calculated intersection angles between respective wave plates in the wave plate group and the horizontal axis of the reference coordinate system, rotating the wave plates in the wave plate group to compensate the optical phase delay generated by the optical system to be compensated in optical phase delay.
Description
technical field [0001] The invention relates to the technical field of crystal wavefront phase compensation and the technical field of polarization modulation, in particular to a wave plate group design method for compensating arbitrary optical phase delay. Background technique [0002] With the development of optical fiber communication technology, super-resolution microscopy technology, optical fiber sensing technology and other technologies, the precise control of optical phase has brought higher requirements. Due to the existence of various polarization devices in the optical system, the optical phase delay will be induced, and then the polarization state of the light will change, which will directly affect the energy utilization rate or imaging effect of the optical system. Therefore, the optical phase delay caused by non-design factors in the optical system must be compensated to eliminate or reduce the influence of the optical phase delay caused by non-design factors ...
