Video Sample Data

With the OneView camera, always have a “live” experience when you capture 16 MP still images and videos on your transmission electron microscope (TEM).

At 25 frames per second (fps) you can capture sharp images when you eliminate sample drift caused by environmental, mechanical and thermal sources. As frames are summed together, a proprietary drift correction algorithm aligns each frame to build a single image.

This video shows the simulation of sample drift by physically pushing back and forth on the TEM column during image acquisition.

Manually rotate sample while live viewing in DigitalMicrograph^® 3: At tenths of a degree at a time.
Align quickly to a known feature: Simply draw a line for reference and orient your sample image with a click.
Capture final image during acquisition: Consistent data analysis with no additional time spent on image processing.

OneView IS movie shows the same sample displayed in Au nanoparticle sintering (video 1 and 2) in the OneView media library, however it is cropped to a smaller region of interest. During in-situ recordings, individual images at obtained at full resolution (4k x 4k) so you can create high resolution movies from the entire sample area or just a sub-region.

Sample: Au nanoparticles; beam energy: 300 kV; original image size: 4k x 4k; frame rate: 25 fps

OneView IS movie shows full field of view (35 x 35 nm²). Video displays Au nanoparticle sintering at 1k x 1k resolution as images were binned x4. During in-situ recordings, individual images at obtained at full resolution (4k x 4k) so you can create high resolution movies from the entire sample area or just a sub-region. This is the first of three videos on Au nanoparticle sintering found in the OneView media library that show how sample details are maintained in smaller regions of interest.

This gallium nitride/indium gallium nitride (GaN/InGaN) quantum well structure is popular in the fabrication of LED products. The OneView camera enables users to record diffraction pattern movies using the in-situ mode option. See original sample labeled [110] high resolution image of GaN/InGaN in the OneView media library.

The OneView IS particle tracking feature lets you define the area of interest, then automatically maintain that area in the center of your display while collecting in-situ data. This movie was taken with Track Particle feature on, allowing the particle of interest to stay stationary in the field of view. See OneView IS particle tracking, part 1 video in the OneView media library to compare the particle movement in the original dataset. 

The OneView IS particle tracking feature lets you define the area of interest, then automatically maintain that area in the center of your display while collecting in-situ data. See OneView IS particle tracking, part 2 video in the OneView media library to compare how the particle of interest stays stationary in the field of view when the Track Particle feature is on.

In-situ results are best viewed in a movie format, but, depending on the number of frames chosen to sum throughout the stream, data can suffer from blurred detail caused by the drift or shift between each image. This video demonstrates how the OneView camera can average 5 frames using the frame alignment function during post-processing. As the sample drifts, averaged frames stay sharp to attain high-resolution results.

Some samples, like this zeolite catalyst, are so beam sensitive that they are distorted and destroyed quickly under the electron beam. This makes it nearly impossible capture a good image. This video acquired using the OneView camera demonstrates how the fast image acquisition rate combined with live drift correction, delivers a sharp, high-resolution image.
