A system and apparatus for navigating and tracking a robotic platform includes a non-contact velocity sensor module set positioned on the robotic platform for measuring a velocity of the robotic platform relative to a target surface. The non-contact velocity sensor module set may include a coherent light source that is emitted towards the target surface and reflected back to the coherent light source. Measuring the change in intensity of the reflected coherent light source may be used to determine the velocity of the robotic platform based on the its relationship with the principles of a Doppler frequency shift. A communication unit may also be utilized to transmit data collected from the non-contact velocity sensor set to a computer for data processing. A computer is then provided on the robotic platform to process data collected from the non-contact velocity sensor set. A user may then monitor the determined trajectory path of the robotic platform and transmit navigation instructions to the robotic platform based on the received trajectory path data.

Robotic autonomous navigation and orientation tracking system and methods

A Compton tomography system comprises an x-ray source configured to produce a planar x-ray beam. The beam irradiates a slice of an object to be imaged, producing Compton-scattered x-rays. The Compton-scattered x-rays are imaged by an x-ray camera. Translation of the object with respect to the source and camera or vice versa allows three-dimensional object imaging.

Compton tomography system

The present invention provides systems and methods for x-ray imaging. In some embodiments, an aperture, or a plurality thereof, are configured to have image transfer functions lacking a zero within a usable spatial frequency range. In further embodiments, the image transfer function is determined according to the shape of the aperture and the usable spatial frequency range is determined according to a usable signal to noise ratio.

X-ray imaging system and method

A quantum-imaging system for detecting photons, including short-wavelength (&#x3c;1 nm) photons, is provided. A quantum imaging system can include optical read-out and optical means, and can be configured to perform as both a photon counter and a photon spectrometer. A quantum-imaging system can function as a photon counter and be configured to measure photon beam fluences (e.g., in J/cm) for both strong beams and weak beams, the latter ones, for example, in the intensity range of 1 pJ/cmsec, or 0.1 &#x3bc;Sv/h. The quantum-imaging system can also function as a photon spectrometer and can be configured to measure photon energies with high energy resolution such as, for example, 1% of photon energy.
