High resolution USB linear array CCD (with synchronous analog output function, BCB and VC source code)
CCD chip: Toshiba TCD1304AP, the pixel size is 8um * 200um, the pixel is 3648, the wavelength range is 300nm ~ 1100nm.
AD sampling rate: 125kHz.
AD sampling depth: 16Bit.
USB 2 interface, the USB interface chip is FT245, the maximum communication rate is 1MByte.
CCD driver and data sampling control circuit is completed by FPGA Cyclone.
CCD integral exposure time 1ms~100ms adjustable.
Trigger mode is optional for internal or external trigger software programming.
When triggered, the CCD sampling speed is 10 frames per second.
The trigger frequency can be set according to the need of 100Hz ~ 1Hz between any frequency, single trigger can also be.
CCD image data on the one hand can be input to the computer through the USB, on the other hand can also be obtained by the analog output port by oscilloscope display or by other cards.
The synchronous trigger output port can trigger the internal clock signal or the external trigger signal synchronously, and can be used to trigger an oscilloscope, which is synchronized with the analog signal of the CCD image.
Test software written by C++ Builder Borland, the source code will be sent to the customer with the CCD circuit board.
In addition to providing BCB of the source code routines, the random comes with C++ Visual's source code routines. Users can modify their own special software on this basis. If users need to use other software such as VB, Delphi or Labview to write, you can log on to the official website of FT245 vendor (http://www.ftdichip.com/Support/SoftwareExamples/CodeExamples.htm) download the corresponding routines, customers can embed CCD data acquisition, CCD integral time and inside and outside the command can be used to control the CCD.
The CCD (TCD1304) model of the linear array and the HR4000 spectrum of the ocean optical is the same as the linear array CCD, the driving circuit is also very similar, so the customer can use the CCD to develop the spectrometer.
The external trigger function of this CCD can be used to capture the low frequency and even single laser pulse.
Using the linear array CCD to scan, can measure the large diameter of the spot (>2cm) image.
Drive circuit board and CCD sensor can be installed separately, by connecting the cable length between the two, 5cm~1m optional.
Has been successfully applied to the spectrometer, measuring the 10fs Ti sapphire femtosecond laser spectroscopy, specifically to see the picture above.
The line array CCD sensitivity is particularly high, so you can measure very weak laser; of course, the user when in use to the laser enough then decay into the photosensitive surface of CCD, or otherwise make CCD saturation or burn out the photosensitive unit.
