C-BLUE One UV global shutter sCMOS camera, in a nutshell

C-BLUE One UV is an industrial-grade ultraviolet-optimized scientific camera which opens new possibilities for high-speed CMOS imaging. The camera offers a spectral sensitivity from 200 to 1000 nm.

Equipped with a high-performance monochrome CMOS global shutter sensor with a very high resolution of 8.1 MP (2848 x 2848 pixels, 2.74 µm pitch), the camera is optimized for the 200 – 400 nm wavelength range with more than 50% quantum efficiency at 300 nm, and 30% at 220 nm.

C-BLUE One is a GigE Vision camera and GenICam compatible.

 

C-BLUE One UV global shutter sCMOS camera, in more details

The C-BLUE One UV camera offers a very low readout noise enabling imaging in ultra-low light conditions from visible to near-infrared, simultaneously with a global shutter architecture, enabling artefact-free acquisitions in dynamic imaging.

Rolling shutter vs. global shutter:

For a CMOS sensor, there are two ways to acquire an image:

  1. Rolling shutter: The acquisition is made one line after the other, the sensor reads each line of the array sequentially. Pixels are exposed with a temporal shift from one pixel to the next.
  2. Global shutter: The full array is exposed entirely at once. All the pixels begin and end the exposure simultaneously. At the end of exposure, the image is transferred to the memory. Then, the image is read-out while the next one is being exposed.

The acquisition mode is an intrinsic characteristic of the camera. However, it is important to understand the differences that will occur in an experimental context when using a camera with rolling or global shutter. Global shutter is highly advantageous for dynamic imaging applications for few reasons:

  1. Artifact-free: In rolling shutter when the image readout speed cannot match the object’s motion, there is temporal under sampling. A spatial distortion of the moving object, often  referred to as the ‘rolling shutter effect’ appears. The larger the object and the faster the movement, the worst is the distortion. Additionally, as the sensor gets larger and with a higher resolution, the readout of the sensor will take longer, hence, the distortion will get worse. This artefact is different from motion blur which occurs in both global and rolling shutter when the integration time is too long compared to the object’s speed.
    A well-known example of the rolling shutter effect occurs when imaging the rotation of blades or propellers. The figure below shows images of a rotating fan acquired in both rolling shutter mode (with a Nikon D500 camera) and global shutter mode (with C-BLUE One). Significant spatial distortion of the fan propellers is visible when using rolling shutter.
  2. Temporal correlation: Even in the absence of distortion the top and the bottom of an image acquired in rolling shutter will not be captured at the exact same time point. Different regions of the image are not correlated in time to other regions. Whereas with global shutter, all pixels are exposed at the same time, allowing for accurate temporal correlation of different areas of the sensor.
  3. Simpler and faster synchronization: Synchronizing a rolling shutter camera to other components, such as a light source, can be difficult due to the time delay between the lines of the sensor. This may result in slower cycle times and frame rates relatively to those achievable in global shutter.

Why is C-BLUE One UV a game changer?

Rolling shutter uses simpler pixel architecture than global shutter. Therefore usually rolling shutter is less noisy than global shutter, this is why this architecture is used in scientific applications but with all its drawbacks. With C-BLUE One UV,  simultaneously and for the first time a global shutter architecture and low noise is made possible, which is a major improvement for fast acquisition scientific applications.

By combining a global shutter and high frame rates (up to 170 fps in full frame) to very low noise, C-BLUE One UV opens new perspectives for applications that simultaneously require truthful/deformation-free images, high temporal resolution, and high sensitivity.

C-BLUE One UV will open new horizons for low noise high speed visible imaging.
