Societal Impact
- By reducing complex instrumentation, it can be used in remote areas with less technical facilities
- Improved image quality even while using a normal camera which eliminates the need for costly detectors
Salient technical features and Advantages of the Technology
- Multiple optical line sources are positioned around the turbid medium like human and animal tissue, blood, milk, etc. which illuminate the medium from different angles. This system eliminates the need for scanning the sample which simplifies the instrumentation and improves temporal resolution.
- The system is configured to reconstruct the three-dimensional optical and dynamic properties of the turbid media using a two-dimensional media captured by the detector.
- A camera can be employed as a detector to quantify speckle contrast since this method increases signal-to-noise ratio, and allows deep imaging with inexpensive detectors.
- The system compensates for the decay rate bias of a single optical line source by using multiple sources and improves temporal resolution.
- It increases the number of photons and effective area within biosafety limits for in-vivo imaging which increases detection area of the detector without changing dynamic range.
