Abstract: A scintillation apparatus design is provided which eliminates the requirement of an optical window between the scintillator and the photosensitive device. The disclosed design provides significantly improved performance with a scintillator mounted directly to the photosensitive device. Improved light coupling between the scintillator and the photosensitive device is achieved. The present disclosure improves the light transmission to the photosensitive device (PSD) by direct coupling of the photosensitive device to the scintillator. By eliminating the need for an optical window, light loss due to the glass interface caused by the optical window likewise may be eliminated. The improvement of light transmission to the PSD improves the gamma ray energy resolution. The quality of the gamma spectroscopy is improved with this design. Furthermore, providing the means and method for evacuating the internal assembly significantly improves the reliability and lifespan of the detector assembly.

Abstract: The present invention provides for very fast detection of gaze direction using retro-reflected light from the ocular fundus that is cost-efficient, small, and portable. These eye trackers are useful in many areas of science and technology, including but not limited to remote control, space, defense, medical and psycho-physiological applications, to identify for example subtle neurologic deficits that occur with cerebellar or vestibular disorders, Parkinson's disease, strokes, traumatic brain injury, possible concussions during sports matches, some forms of reading disability, or simply fatigue or inebriation. In ophthalmology, with two such devices operating simultaneously, the variability of relative eye alignment over time can be measured, without requiring individual calibration, and without requiring fixation on a specified target, ideal for use with small children. Such instruments have widespread application as noninvasive screening devices in infants and young children or patients of any age for defects of binocular function such as strabismus and amblyopia.

Abstract: A dual-spectrum photocathode capable of emitting photo-electrons into a first vacuum space includes a first photodetector array formed using a first optoelectronic material that generates photo-electrons responsive to incident electromagnetic energy in a first spectral band. The dual-spectrum photocathode also includes a second photodetector array formed using a second optoelectronic material that generates photo-electrons responsive to incident electromagnetic energy in a second spectral band that is different from the first spectral band. The first spectral band may include the visible electromagnetic spectrum between 390 nanometers and 700 nanometers and the second spectral band may include the short-wave infrared (SWIR) electromagnetic spectrum above 900 nanometers.

Abstract: An electron source of an X-ray fluorescence analyser includes a photon source (201) and a photoelectric converter (203, 204) for converting photons into electrons. An electron multiplier (203, 204) multiplies the electrons, and a focusing element (206, 207) focuses them to a beam. A gastight casing (209) encloses the photoelectric converter and the electron multiplier (203, 204). An electron-transparent membrane (213) covers a first opening in the casing at a location where the focused electron beam is directed out of the casing.
