Traditional CD read and write mainly carries out in CD-ROM drive, and the laser head of CD-ROM drive is the enforcement division from CD read and write information
Part, but conventional optical disc read-write is mainly carried out in a manner of simple scan, read or write speed is slower, in big data field of storage, so
Urgent need invents one kind and rapidly and efficiently reads and writes optical storage technology.In recent years, with digital space micromirror reflector (Digital
Mirror Devic abbreviation DMD) manufacturing process continuous promotion, accelerate the marketization of DMD, and then pushed it by many necks
Domain application, its apparent advantage of DMD are mainly reflected in the advantages that pixel is small, and packing ratio is high, fast response time and high contrast, base
The hot spot of digital optical lithography is increasingly becoming in the digital photolithography system of DMD.Advantage of the DMD in system application is to be more suitable for
Quickly, the field of lithography of large area processing, in conjunction with electronic mobile platform, it can be achieved that instantaneous exposure splices.Optical microscopy its
Have the characteristics that wide field imaging, refers to through sample or from the reflected visible light of sample, after one or more lens,
It can obtain the technology of the enlarged drawing of tiny sampler.Gained image can directly be observed with eyes by eyepiece, can also be used
Photographic plate or digitized image detector such as CCD, CMOS are recorded, and can also be carried out on computers at display and analysis
Reason.So in conjunction with DMD digital optical lithography and optical microscopy imaging technology, it can be achieved that the optical information number of image-type concurrent reading and concurrent writing
Storage.
