Abstract: An angle-stable, miniaturized and integrate-able imaging system based on plasmon resonances or dielectric resonances for multispectral imaging maintaining full spatial resolution of the image sensor. Active tunability of the filter allows color recording, estimation of unknown spectra and determination of spectral singularities, for example laser lines, with the use of a conventional B/W camera. The system is characterized by high angular acceptance, cost-efficient fabrication and ease-of-use. This system can be used in conjunction with other commercial multispectral imaging systems such as RGB cameras to further enhance the spectral resolution. It can be adapted to different spectral ranges, depending on the application.

Abstract: An imaging system may include several different types of pixels that are each configured to detect different characteristics of light received at the imaging system. An imaging system may include image sensing pixels that detect the wavelength and intensity of the light, direction sensing pixels that detect the directionality of the light, polarization sensing pixels that detect a polarization state of the light, and diffractive wavelength separation pixels that detect multiple different wavelength components of the light. One or more pixels of the different types may be arranged in a pixel cluster. A pixel cluster that includes different pixel types may detect spatially correlated information for multiple characteristics of the light. Multiple pixel clusters may be arranged in a pixel array that generates an image based on spatially correlated information for the different characteristics of the light.

Abstract: Methods and systems for performing spectroscopic reflectometry measurements of semiconductor structures at infrared wavelengths are presented herein. In some embodiments measurement wavelengths spanning a range from 750 nanometers to 2,600 nanometers, or greater, are employed. In one aspect, reflectometry measurements are performed at oblique angles to reduce the influence of backside reflections on measurement results. In another aspect, a broad range of infrared wavelengths are detected by a detector that includes multiple photosensitive areas having different sensitivity characteristics. Collected light is linearly dispersed across the surface of the detector according to wavelength. Each different photosensitive area is arranged on the detector to sense a different range of incident wavelengths. In this manner, a broad range of wavelengths are detected with high signal to noise ratio by a single detector.
