Abstract
The invention discloses a high-speed microscopic image collection system based on time-sharing control. The system is provided with at least two cameras for collecting image information. The cameras send collected image information to a PC through a lens and an electronic objective lens. The PC outputs a focusing signal through a focusing driving mechanism to the electronic objective lens. The objective lens sends the image information to different cameras through a beam splitter. A sequence controller outputs start signals to all cameras. The system is advantaged in that through a plurality of cameras for collecting the image cooperatively, high-speed microscopic image collection is achieved. The system not only reduces device cost but also increases precision and speed of collecting the images by means of the device.

Detailed description of the invention
High speed micro image collection system based on Time-sharing control is provided with the camera 4 (imageing sensor) gathering image information, and camera 4 includes but not limited to face battle array CMOS, CCD, InGaAs, monochrome or color camera 4.
The image information of collection is delivered to PC1 through lens 5 and electronic objective 7 by camera 4, and the image information of any collection is sent to interface and the agreement of PC1, includes but not limited to USB3, IEEE-1394, GigE, Camera-link, CoaXPress, or PCIe.PC1 exports focussing signals to electronic objective 7 through focusing driving mechanism 2, in order to improve camera 4 acquisition rate, camera 4 is at least provided with two, graphical information is delivered to different cameras 4 through beam splitter 8 by electronic objective 7, and sequence controller 3 exports enabling signal extremely each camera 4, controls each camera 4 and gather image information one by one, in addition, camera 4 is furnished with flash lamp 6, and sequence controller 3 exports enabling signal simultaneously and gathers image information to flash lamp 6, cooperation camera 4.Flash lamp 6 includes but not limited to xenon lamp, laser, LED, Halogen light or plasma source.Flash lamp 6 wave-length coverage includes infrared, it is seen that light, ultraviolet, deep ultraviolet.
If the frame per second of a camera 4 is 600 width/s. just can obtain the image of 4x600 width/s=2400 width/s by the acquisition time system of 4 cameras 4.
According to the image capture interface of USB3, data acquisition and the transfer rate of the fastest camera 4 the most commercially can bought are about 350MB/s.Use the image acquisition time technology of this invention, with four cameras 4, overall image acquisition rates then can reach 1.4GB/s., and this will be the fastest image acquisition rates that single PC1 can reach without image pick-up card in (2016) worldwide at present.
According to the image capture interface of CoaXPress, data acquisition and the transfer rate of the fastest camera 4 the most commercially can bought are about 2.2GB/s.Using the image acquisition time technology of this invention, with four cameras 4, overall image acquisition rates then can reach 8.8GB/s.
, following two embodiment can be there is in setting based on camera 4:
1 one object lens of embodiment join multiple mirrors and camera 4, as shown in Figure 1, camera 4 is provided with four, and each camera 4 is furnished with independent lens 5, each two camera 4 and lens 5 thereof constitute the light-path connecting second level beam splitter 8 through a first order beam splitter 8, and second level beam splitter 8 and flash lamp 6 light output end are connected the light-path of electronic objective 7 through the 3rd beam splitter 8 composition.I.e. in the directional light part of imaging optical path, being divided into two by 8 imaging beams of beam splitter, then two are divided into four, and each camera 4 has respective lens 5.
