[background technology]
Stereo microscope is that it can form the small items of being observed and amplify and upright three-dimensional space image by the common combination of the lens of difference in functionality and microscope basic machine.Observing aspects such as small items that eyes unable directly sees and object microstructure, stereo microscope has the irreplaceable effect of other any microscope equipment.And, up to now, be human knowledge and one of main means of handling microworld always.
But traditional stereo microscope comes image output with a pair of eyepiece, in order to watch stereopsis clearly, requires the pupil of beholder's binocular to overlap with the emergent pupil of microscope ocular.This just makes beholder's position receive serious limit, and beholder's eyes and human body are very easy to tired.Therefore long-term user suffers from the disease of aspects such as cervical vertebra, lumbar vertebrae extremely easily owing to be in same static position state for a long time.For this reason, countries in the world researcher and stereo microscope manufacturer are devoted to the microscopical research and development of novel solid always, and purpose is to design the stereo microscope that ergonomic requires, thereby eliminate long-time vision and the physical fatigue that causes of observing.
In the China of the nineties in 20th century and in other world wide at the end of the eighties; Microscopical research and manufacturer are that microscopic system has increased by a cover television pick-up equipment; By ccd video camera micro-image is shown on the display on plane or monitor, solved some problems to a certain extent.But, because the micro-image that this mode can only display plane, so only can't watch micro-stereo-picture from display or televisor.Therefore, can only still can't operate small items, finally also must watch and handle micro-object with binocular eyepiece as the usefulness of watching or watching the search of scope qualitatively roughly to microscopic objects through watching television image.
The man-machine interface that thoroughly solves microscopic system is the direction of countries in the world correlative study person and manufacturer's effort always.Got into since 21 century, in west advanced person's the optical instrument manufacturing enterprise, minority enterprise has adopted the stereo-picture technology, and hope can fundamentally solve the problem of the ergonomics aspect of stereomicroscope existence.In western developed country, the world-renowned optical instrument enterprise of minority successively releases the microscope equipment that some have novel man-machine interface.The Vision company of Britain adopts visual field expansion technique (Expand pupil) to develop the stereomicroscope of ocular glass free; Enlarge the operating distance of microscope emergent pupil; The beholder can freely be watched in certain scope; Thereby eliminated visual fatigue to a certain extent, made operator's head and trunk activity freely.
Adopt various feasible technology, make stereomicroscope in use, beholder's eyes are broken away from the constraint of eyepiece, and this is the inevitable development trend of stereoscopic microtechnic in digital times.Traditional stereomicroscope has obtained in fields such as biology, medical science, mineral products, public security, procuratorial work using widely at present, develops the digital stereoscopic microscopic system of the stereoscopic micro-notion that breaks traditions, and will bring revolutionary impact to each related application field; Simultaneously, because it has broken through the man-computer mode and the observing effect of existing stereomicroscope, also will expand the application and the scope of this product effectively, its market outlook are self-evident, have good social benefit and economic benefit.
Yet there is limitation in the existing microscope stereopsis microtechnic that realizes, and not mature enough, implements also very difficulty.
