High-Accuracy Receiver for Optical Object Discrimination

Case ID:

This invention describes a device that functions as a highly accurate and complex receiver for optical object discrimination. This technology has applications and improvements in a large range of object-discrimination-based technologies, such as QR or barcode readers.


Object discrimination technologies are widely used and have wide-ranging applications in various industries. The current standard and closest technology would be QR and passive barcode readers. The inventors have devised a new device and method that improves on applications and accuracy.

In this technology, the receiver will be utilized in high-stability contexts where 1- or 2-dimensional visual codes or other objects must be read or identified using small optics at large distances. Additionally, the technology will be a vast improvement in situations where the use of RF or other active signaling is precluded, such as in automated sensing contexts.


  • Optical object discrimination device using spatial mode analyzer or spatial parity sorter for the purpose of arbitrary 2D object classification
  •  Potential applications in astronomy, medical imaging, and other optical microscopy


  • Highly accurate
  • Diverse range of object discrimination applications
