Abstract: Information is encoded in an image signal by exploiting spectral differences between colors that appear the same when rendered. These spectral differences are detected using image sensing that discerns the spectral differences. Spectral difference detection methods include using sensor-synchronized spectrally-structured-light imaging, 3D sensors, imaging spectrophotometers, and higher resolution Bayer pattern capture relative to resolution of patches used to convey a spectral difference signal.

Abstract: An electronic device may have a display with a brightness that is adjusted based on ambient light data from one or more ambient light sensors. An ambient light sensor may include at least one silicon-based photosensor. The silicon-based photosensor may generate a corresponding raw sensor reading. Processing circuitry associated with the ambient light sensor may analyze the raw sensor reading to determine the type of light source that is present by comparing measurements from at least two different photosensors, by determining the color temperature of the light source, and/or by determining the modulation frequency of the light source. A compensation factor may then be selected by referring to a lookup table. The processing circuitry may compute a compensated sensor reading based on the raw sensor reading and the selected compensation factor. The brightness of the display may be adjusted based on the compensated sensor reading computed in this way.

Abstract: An optical imaging system and method including a movable pixelated filter array, a shutter mechanism to which the pixelated filter array is attached, and a controller configured to implement a data reduction algorithm. The shutter mechanism is configured to move the pixelated filter array into and out of the optical path, and the data reduction algorithm allows the controller to account for axial and/or lateral misalignment of the filter array relative to the imaging detector array or its conjugate. In certain examples, the controller is further configured to use the data reduction algorithms also to perform wavefront sensing, for example to estimate wavefront error.

Abstract: An optical filter includes a first variable wavelength bandpass filter that extracts light of a first wavelength band and has first and second spectral bands and a second variable wavelength bandpass filter that extracts light of a second wavelength band adjacent to the first wavelength band and has third and fourth spectral bands. Part of the period during which the light of the first spectral band is extracted overlaps with the period during which the light of the third spectral band is extracted, and part of the period during which the light of the second spectral band is extracted overlaps with the period during which the light of the fourth spectral band is extracted.

Abstract: A method and apparatus for dating a dating a body sample, such as blood, includes taking at least one spectroscopic measurement (37) of the sample at least two predetermined positions in the spectrum having spectral characteristics corresponding to at least two predetermined substances present in the sample that have a time varying relationship with each other. A measured relative concentration of each of the predetermined substances is then determined (41) from the measurement, and the measured relative concentrations of the two predetermined substances is compared (43) with a known variation of the relative concentrations of the two predetermined substances over time. A good fit of the measured relative concentrations to the known variation of the relative concentrations is then determined, so as to provide an indication of the age of the sample (44). Alternatively, instead of measuring the relative concentrations of each of the predetermined substances, the rate of change of the relative concentrations is determined.
