Inside Cover: Ultrafast cell edge detection by line‐scan time‐stretch microscopy (J. Biophotonics 1/2019)
An ultrafast time‐stretch imaging technique for edge detection is demonstrated. The edge detection based on the optical directional derivative is realized by using differential detection. Since the edge detection is implemented in the physical layer, the computation complexity in the back‐end digital signal processing is very low. The blood red cells and cancer cells can be easily identified by distinguishing the edges.

Keeping up-to-date with research can feel impossible, with papers being published faster than you'll ever be able to read them. That's where Researcher comes in: we're simplifying discovery and making important discussions happen. With over 19,000 sources, including peer-reviewed journals, preprints, blogs, universities, podcasts and Live events across 10 research areas, you'll never miss what's important to you. It's like social media, but better. Oh, and we should mention - it's free.
Researcher displays publicly available abstracts and doesn’t host any full article content. If the content is open access, we will direct clicks from the abstracts to the publisher website and display the PDF copy on our platform. Clicks to view the full text will be directed to the publisher website, where only users with subscriptions or access through their institution are able to view the full article.
