Abstract
The present disclosure provides a continuous zoom stereoscopic microscope with an adjustable stereoscopic angle, consisting of a microscope stand, a first eyepiece module, a second eyepiece module, a first objective module, a second objective module, a first Risley prism, a second Risley prism, a first image-rotating prism, a second image-rotating prism, a drive module, a control module and an illumination module. The drive module provides preset drive values for individual liquid lenses in the liquid lens sets according to different magnifications to change the focal lengths of the liquid lenses, thereby changing the effective focal lengths of the objective module and that of the eyepiece module, and finally achieving continuous and fast zooming of the stereoscopic microscope to be adapted to different working scenarios. The control module controls the relative angle between the two wedge-angle prisms in the Risley prism, achieving the continuous adjusting of the stereoscopic angle of the stereoscopic microscope, and then acquiring stereo images with different stereo senses.
