摘要： This invention comprises the means for the capture of full spectrum images in an electronic camera without the use of color primary filters to limit the spectral color gamut of the captured image. The fundamental principle of the invention is that each pixel of the image sensor acts as an independent spectrophotometer and spectral separator.Electromagnetic energy enters though a slit or collimating optic.Electromagnetic energy gets diffracted into component spectra by diffraction grating spectrophotometer for each pixel of imageElectromagnetic energy leaves diffraction grating at different angles based on wavelength of the energySpectrophotometer separates light for each pixel into its spectral components onto photodetector line array elements.Individual line array elements which are activated determine the original radiance level of the light source containing that specific wavelength region. The sum of these regions determines the spectral signature of the light at that pixel element.Many pixels arranged in a two-dimensional matrix would generate the image frame. Sequencing frame yields a full-spectrum moving image.

摘要： An apparatus providing full spectrum electronic images includes a full-spectrum light source, a programmable diffraction grating to separate light from the source into its spectral components, a reflection system controllable on a pixel by pixel basis to modulate light output from the diffraction grating, and a scanning mirror to form an image from light modulated by the reflection system. A related method for displaying a full spectrum image includes providing full spectrum light, using a diffraction grating to separate the light into its spectral components, and for each pixel of the image, modulating the intensity of the spectral components to produce a light output characteristic of such pixel, and additionally using a scanning mirror arrangement to form the image.

摘要： In order to provide a microprocessor based fault tolerant computing system, hardware counters or event monitors that are normally included on the microprocessor chips are used to count application instructions that are being executed by the microprocessors. By counting the instructions and preempting the execution of the application program after a predetermined number of instructions have been executed, it is possible to cause the application programs to execute in congruent frames so that results from the application can be checked at congruent points of their execution. If the results do not match, then the program can be terminated or if a number of microprocessors are being used, the results can be voted on and the ones that match can be used in further computation by the system.
