Spiking retina microscope
| DWPI Title: Spiking retina microscope for capturing and processing optical microscopy images, has neuromorphic imaging sensor comprising sensor elements that are configured to generate spike signals in response to integrated light from magnified image |
| Abstract: A spiking retina microscope comprising microscope optics and a neuromorphic imaging sensor. The microscope optics are configured to direct a magnified image of a specimen onto the neuromorphic imaging sensor. The neuromorphic imaging sensor comprises a plurality of sensor elements that are configured to generate spike signals in response to integrated light from the magnified image reaching a threshold. The spike signals may be processed by a processor unit to generate a result, such as tracking biological particles in a specimen comprising biological material. |
| Use: Spiking retina microscope for capturing and processing optical microscopy images. Uses include but are not limited to three dimensional reconstruction, depth estimation, motion segmentation, pose estimation and visual-inertial odometry. |
| Advantage: The microscope utilizes event-driven sensors to detect events with microsecond resolution, so that the microscope can capture very fast motions without suffering from motion blur. The microscope reduces power required for operating the neuromorphic imaging system as the sensor works independently, and transmits information of event change as soon as the event change is detected. |
| Novelty: The spiking retina microscope (100) has microscope optics (102) to direct a magnified image (108) of a specimen onto a neuromorphic imaging sensor (104). The neuromorphic sensor has a set of sensor elements (116,118) to generate spike signals in response to integrated light from the image reaching a threshold. Each spike signal identifies a location in the image and a time of occurrence of the spike signal. A processor unit (105) processes the spike signals to generate a result. The processor unit processes the signals to track biological particles in the specimen. |
