اطلاعات بیشتر

QHY1253 has IMX253 Global shutter CMOS sensor with the special Polarize version.  Monochrome and color version are also available. Compared with QHY550P, 1253P has a bigger sensor. It has important applications in gemstone, geology and material science, biology science.

QHY1253 has build-in two stage TEC cooler. It can cooled the sensor to -35C below ambient and reduce the dark current, which greatly improving the dark signal detect performance. Especially for detect the tiny difference of the polarize light. This is necessary for the astronomy, life science and optical lab.

Polarize Sensor

With  the on-pixel four direction polarize filter, A ploarize sensor can capture the polarize image at only one exposure. No need change the polarize filter for three times. Polarize detector can be used in industry image to detect the scratch, transmissible object and getting the no-reflection pictures.

Since the polarizer is formed during the semiconductor process, form and formulation of polarizer, uniformity, mass productivity and durability are excellent compared to conventional polarization sensors. Furthermore, The Polarization sensor is covered with an anti-reflection layer which helps to reduce reflectance and avoids poor flare and ghost characteristics.

Global Shutter

Unlike the rolling shutter technology used in most CMOS cameras, a global shutter guarantees that the exposure time for the whole image area is uniform, beginning and ending at exactly the same time. This type of shutter is ideal for high precision applications. For high speed moving object and the atmospheric agitation the global shutter can generate undisborted imaging and realizes high picture quality.

User Guide
External Trigger Mode Manual
Suitable for the following camera with a global shutter.
Use Sharpcap software as the capture software. QHYCCD Advnanced tools as the External trigger mode setting software.
1.Run SharpCAP, You will see the live video appearing
2.Run advanced control tools. Check on the “SDKAPI_MODE” Click “Coonect”
Mode 1:Hardware External Trigger. The exposure time is depent on the external pulse width
In the Trig Input Souce trigger input source drop-down selection, select Trig Input Pin Direct. The meaning is to trigger the input source as the external trigger input port of the camera (opto-coupled isolated, RCA gold plug); Select one in Trig Controller Source (the marquee doesn’t make sense for this mode, so choose one)

 

Press the TRIG MODE ON button. You will find that the video image in sharpCAP software stops. The camera has entered a waiting outside trigger state. Trigger the input port via the photoelectric isolation and enter a high level. You’ll find that the image takes a frame, and the longer the duration of the high level, the longer the image will be exposed. In this mode, the exposure time is equal to the duration of the high level.

Mode 2:Out-of-hardware trigger, exposure time set by the software
Press the diagram to set it up. Choose XTRIG CONTROLLER in Trig Input Source, Trig Input Phase to Rise Edge, Trig Controller Controller Enable Source select Trig Controller by Hardware. And enter exposure time, such as 50ms. Then click the TRIG MODE ON button to complete the setting of the mode and the exposure time setting.
By triggering the input interface outside the photoelectric isolation, a short high level is entered and a frame is captured on the image in SHARPCAP. Note that if the input is consistently high, the camera continues to shoot under the setting of a longer exposure time. To avoid continuous shooting, the high-level time of the input trigger is short, e.g. 1ms
Mode 3: Out-of-software trigger, exposure time is determined by the software command interval
In this mode, the software sends a start exposure instruction through the software, and then the software waits for a delay. Then send an end exposure instruction. A trigger for software control is possible. Its exposure time is equal to the time between the start and end exposure commands. Just follow the settings below. Once set up, click TRIG MODE ON to feed the instruction. Then click on the Software Register Trig Test button to observe the shooting. To modify the exposure time, you only need to modify the value sits in the exposure time box, instead of clicking TRIG MODE ON, just click the RegisterSoftware Trig Test button.
Mode 4:Out-of-software trigger, exposure time set by the software
In Mode 3, there is a problem with a less stable and accurate exposure time. The reason is that the time interval between the two instructions sent by the upper computer is not so precise and will be affected by CPU delay, busyness and other factors. Therefore, mode 4 is also provided. Set the pattern as shown below.
In this mode, exposure time is set by the software and performed by the hardware inside the camera, rather than by the interval between the two commands that the upper machine starts and ends exposure, so the exposure time is accurate and repeatability is very good. The upper machine only needs to issue a start exposure and end exposure instructions. The interval between the two instructions is as short as possible, for example, about 1ms. The camera will be exposed according to the exposure time set by the software, not the command interval.
Mode 5: Out-of-hardware trigger, sequence shooting
In this mode, continuous shooting can be achieved by means of external triggering. The camera is waiting until a trigger signal is given, and once a trigger signal is given, the camera starts shooting continuously. Exposure time is set by the software.
Follow the figure below to set it up. Once set up, press the TRIG MODE ON button to keep the camera waiting, and then enter a high-level pulse from the optically isolated trigger input to trigger continuous shooting by triggering continuous shooting by the camera. (It is important to note that QHY174 does not work when the exposure time is short, and the exposure time is longer.) If you want to enter the next wait state, click TRIG MODE ON to restore the camera to the waitstate and wait for the next external trigger pulse to arrive.
Mode 6: Out-of-software trigger, sequence shooting
Similar to Mode 5, the trigger source is entered from external hardware to software control. After pressing the diagram to set up, click TRIG MODE ON, the camera waits, at this time click on the Software Register Trig Test button, after the start signal, you can see the start of continuous shooting.
Additional instructions:

The SHARCAP software has a random horizontal horizontal stripe noise reduction feature in the right menu bar. CMOS of the global shutter, such as 174, horizontal random horizontal stripes are more obvious at high gain, and this column can be adjusted appropriately. Comparing the image below, there is no on and off effect, and the difference can be seen.
