What is a composite image? A composite is a single image formed by combining multiple frames acquired with sequentially triggered angled LED illumination. Each frame captures different spatial information, and the result is a composite image rich in structural detail. How is a composite image created in HaloMicroscopy? The HaloElement captures up to 15 images from different LED positions. These are automatically combined using a spatial encoding scheme (like positions on a clock face), creating a full-field composite view with enhanced contrast and depth information. What kind of information does a composite HaloImage provide? Composite HaloImages can reveal both surface features and internal structure based on differences in geometry and refractive index. The angular information encoded in the image helps distinguish fine details, edges, and orientations—even in complex samples like fibres, flakes, or tissue layers. Is post-processing required to generate a composite image? A standard composite image is automatically generated by the HaloVision software using 15 sequentially acquired frames. Users also have access to the raw data, enabling custom post-processing in tools like Fiji. For more details, refer to the Image Processing Tutorials. Can I control which frames are used in the composite? Yes. While the default composite includes all 15 angular frames, users can open individual channels in Fiji and selectively combine, color, or process them based on your needs.
