Turn or invert, to make drive focus adjustment runner rotation by gear drive, and sends realtime graphic and extremely focus and judge list
Member judges the focus state of present image, realizes auto-focusing by above-mentioned loop control.
Further, the wavelength of near-infrared camera lenses fluorescence signal collected is 700-1900 nm.
Further, the wavelength of the near-infrared fluorescent detector fluorescence signal collected is 900-1700 nm.
Further, described image work station is at least to be converted to digitized video simultaneously for the near-infrared fluorescent signal
By focusing judging unit and drive control cartoon letters.
Further, the drive control card, at least to receive image workstation transmission driving signal and control watch
Take motor.
Further, the servo motor, at least to carry out focusing adjustment behaviour to near-infrared camera lenses by gear train
Make, including positive and negative rotation.
Compared with the prior art, a kind of autofocus system of near-infrared fluorescence imaging instrument of the utility model is for reality

Near-infrared fluorescent detector, to acquire the near-infrared fluorescent signal (900-1700 nm wave band) and convert
Image workstation is sent into for digital signal.
Image workstation, at least the near-infrared fluorescent signal is converted to digitized video and by focusing judgement
Unit and drive control cartoon letters.
Drive control card, to receive the driving signal of image workstation transmission and control servo motor.
Servo motor, to carry out focusing adjustment operation, including positive and negative rotation to near-infrared camera lenses by gear train.
The near-infrared fluorescent signal (900-1700 nm wave band) of sample to be observed is glimmering via near-infrared camera lenses 1 and near-infrared
Digital signal is converted to by photoelectric chip after optical detector 2, the digital signal after conversion enters image workstation 3 by connection
Processing obtains digitized video, image workstation 3 by the built-in focus state for focusing judging unit real-time judge present image,
And then send commands to the notice control servo motor 5 of drive control card 4 and rotate forward or invert, it is driven to pass through gear drive
The rotation of focus adjustment ring, while focusing the focus state of judging unit real-time judge present image, by above-mentioned loop control from
And realize auto-focusing, resolving power is high, good imaging quality.
The various embodiments described above are merely to illustrate the utility model, wherein the structure of each component, connection type and method are implemented
Process etc. may be changed, all equivalents carried out on the basis of technical solutions of the utility model and change
Into should not exclude except the protection scope of the utility model.
