pco.panda 26 DS 雙快門 sCMOS相機(jī),為您提供一個(gè)高分辨率，緊湊型的雙快門sCMOS相機(jī), 該相機(jī)專為粒子圖像測(cè)速(PIV)實(shí)驗(yàn)而設(shè)計(jì)。

pco.panda 26 DS 相機(jī)采用全局快門功能的sCMOS圖像傳感器,  使其成為雙快門相機(jī)在流體分析中執(zhí)行所有類型的粒子圖像測(cè)速測(cè)量的先決條件。在PIV實(shí)驗(yàn)中，光散射粒子被加入到被測(cè)流中。激光束形成一個(gè)光片，以短脈沖間隔照亮散射粒子兩次Δt ,這個(gè)時(shí)間間隔的下限由相機(jī)的雙快門幀間時(shí)間定義。散射光被記錄在高分辨率數(shù)字相機(jī)的連續(xù)兩幀上。雙快門間隔時(shí)間越短，可分析的流速越高。

pco.panda 26 DS 雙快門 sCMOS相機(jī)還具備很多出色的設(shè)計(jì)。 相機(jī)2.5 x 2.5 μ m2像元大小，超高的空間分辨率非常適合在光學(xué)系統(tǒng)中使用；

使用真電荷域全局快門，可以實(shí)現(xiàn)非常低的讀出噪聲和暗電流；像素結(jié)構(gòu)允許可以讓相機(jī)獲取雙快門圖像，幀間時(shí)間僅為1μs ;

相機(jī)的封裝設(shè)計(jì)和接口都提供極其方便的集成方式。所有的pco.panda相機(jī)都具有超緊湊的體積。此相機(jī)無(wú)需外部電源線纜供電，因其供電和快速數(shù)據(jù)的傳輸可以

通過(guò)一條USB 3.1線纜來(lái)完成。

pco.panda 26DS 相機(jī)在PIV模式下使用雙快門模式的時(shí)序表：

第一次曝光時(shí)間的持續(xù)時(shí)間可以配置。第二次曝光時(shí)間的持續(xù)時(shí)間是固定的，

并由第一次圖像的讀出時(shí)間預(yù)先定義。因此，在延長(zhǎng)的二次曝光時(shí)間內(nèi)，

通常需要防止傳感器受到環(huán)境光的照射。

ultra compact global shutter sCMOS camera

With the pco.panda 26 DS sCMOS camera you get a high resolution, ultra-compact sCMOS camera for particle image velocimetry (PIV) applications.

The outstanding global shutter capabilities of the pco.panda 26 sCMOS sensor make it a perfect candidate for effective double imaging – a prerequisite to perform all types of Particle Image Velocimetry measurements in flow analysis. In PIV, light scattering particles are added to the flow under test. A laser beam is formed into a light sheet, illuminating the scattering particles twice with a short pulse at a time interval Δt. The lower limit for this time interval is defined by the double shutter interframing time of the camera. The scattered light is recorded onto two consecutive frames of a high resolution digital camera.

The shorter the double shutter interframing time, the higher the flow speeds which can be analyzed. There are many details that make the pco.panda 26 DS sCMOS camera outstanding. Its small 2.5 x 2.5 μm2 pixels are an excellent fit to use the resolution capacity in optical systems. Thanks to the pco.panda 26's DS true charge domain global shutter, you can achieve a remarkably low readout noise and dark current. In addition, the pixel architecture allows to acquire double shutter images, with an interframing time of only 1 μs.

The housing design and interface provide easy integration. All pco.panda cameras have ultra-compact dimensions. The lack of needing an external power supply allows power and fast data transfer through one single USB 3.1 Gen 1 cable.
