A detection system and method using multiple detector arrays for single or multi-frequency imaging of an object or scene, with one or more channels arranged along perpendicular axes. A polarizing beam element can be arranged to pass or reflect radiation to first and second detector blocks of the detection system.

A pixel structure having a cladding and tapered core waveguide, the core dimensioned to refract EM radiation through the cladding at differing depth dependent on the wavelength of the radiation, and a plurality of transducers disposed to convert the band of radiation they receive into electrical signals. In some embodiments the transducers are disposed within lateral waveguides, and in some embodiments below the tapered core waveguide. Further disclosed is an image array sensor comprising a plurality of such pixel structures. Further disclosed is an array comprising stacked layered waveguides having transducers disposed therewithin, and a plurality of refractors to refract different bands of EM radiation into differing waveguides.

A rapid method for characterizing and identifying microorganisms using Focal-Plane Array (FPA)-Fourier Transform Infrared (FTIR) spectroscopy is disclosed. Multi-pixels spectral images of unknown microorganisms spectra are analyzed and compared to spectra of reference microorganisms in databases. The method allows rapid and highly reliable identification of unknown microorganisms for the purpose of medical diagnosis, food and environmental control.

A detection system and method using multiple detector arrays for single or multi-frequency imaging of an object or scene. A polarizing beam element can be arranged to pass or reflect radiation to first and second detector blocks of the detection system.

An optical detection apparatus and method for detecting a display panel is provided. The apparatus includes photosensitive units arranged in an array. A minimum distance between adjacent photosensitive units is less than a sub-pixel size of the display panel; the photosensitive units in adjacent rows have a position offset in a first direction; and an offset distance corresponding to the position offset is less than the sub-pixel size of the display panel.

Aspects of the subject disclosure may include, for example, a method, apparatus and computer readable media for analyzing objects using a coherent optical system. This innovative approach leverages dual-polarization coherent modulation to generate optical signals encoded with digital information across multiple dimensions, such as amplitude, phase, and polarization. These signals are transmitted to a target scene resulting in reflected signals that are received and processed to detect and identify objects based on a comparison with the original transmitted signals. These techniques offer significant improvements in accuracy and robustness, overcoming limitations of traditional lidar and depth camera systems, particularly in dynamic or complex environments. The disclosed technology is applicable across various industries, including autonomous vehicles and environmental monitoring, providing enhanced precision in distance, velocity, and polarization measurements. Other embodiments are disclosed.

Methods, devices, apparatus, and systems for three-dimensional (3D) contoured scanning photoacoustic imaging and/or deep learning virtual staining.
