摘要： A gas discharge laser with a pulse multiplier. In the pulse multiplier, short pulses from the laser are divided into portions and all or all but one of these portions are delayed in delay legs by different time periods and recombined to provide a stretched output pulse having substantially reduced intensity and longer duration as compared to the pulse from the laser. Focusing optics are included in each delay leg to assure that beam size and angular spread of each portion of the combined pulse is not substantially different from other portions of the pulse.

摘要： An implantable radiation therapy device includes a biocompatible radiotranslucent outer capsule containing a radiation shielding element and a radioactive isotope at least partially shielded by the shielding element. When the device is at or below body temperature, radiation is prevented or limited from being transmitted through the outer capsule by the shielding element. When non-ambient energy is applied to the device, the shielding element and radioactive isotope are reconfigured such that an increased level of radiation is transmitted through the outer capsule and emitted by the device.

摘要： A catadioptric anamorphic beam expanding telescope expands an optical beam in a first axis substantially perpendicular to the beam propagation axis, and deflects it in a plane substantially perpendicular to the first axis. The beam expanding telescope can include reflective, refractive, and combined reflective/refractive elements. An embodiment includes an off axis convex spheric reflector and an off axis combined reflective/reflective optical element, commonly known as a Mangin mirror, incorporating a refractive first surface and a reflective rear surface, which compensate for aberrations introduced by the off axis deflection of the beam. The telescope is particularly useful for deep ultraviolet (DUV) applications at wavelengths shorter than about 250 nm. In some applications, the telescope illuminates a diffraction grating or other wavelength dispersive element, aligned to retroreflect a preferential wavelength, thereby providing wavelength narrowing. In some applications a combined telescope and diffraction grating are incorporated within a laser optical cavity, thereby narrowing the output wavelength spectrum of the laser. Embodiments are advantageous for intracavity line narrowing in an electric discharge laser, such as a KrF excimer laser, ArF excimer laser, or F2 molecular laser. Additionally, embodiments in accordance with the present invention provide an improved general purpose DUV beam expander.

摘要： The color response of camera devices may be calibrated, using a correction factor that can account for differences in the spectra of light emitted by different light sources used during calibration. The correction factor may be calculated based on the expected spectral sensitivities of the camera devices, the power spectrum of an actual light source, and the power spectrum of a canonical light source. The correction factor is then applied to adjust a measured color response of a given camera device, so that the adjusted color response is effectively the response of the given camera device if it had been illuminated by the canonical light source. In this manner, any measured color response differences, which may be due to differences between the actual light source used and the canonical light source, can be effectively reduced (if not essentially eliminated.) Other embodiments are also described and claimed.

摘要： A high resolution spectral measurement device. A preferred embodiment presents an extremely narrow slit function in the ultraviolet range and is very useful for measuring bandwidth of narrow-band excimer lasers used for integrated circuit lithography. Light from the laser is focused into a diffuser and the diffused light exiting the diffuser illuminates an etalon. A portion of its light exiting the etalon is collected and directed into a slit positioned at a fringe pattern of the etalon. Light passing through the slit is collimated and the collimated light illuminates a grating positioned in an approximately Littrow configuration which disburses the light according to wavelength. A portion of the dispursed light representing the wavelength corresponding to the selected etalon fringe is passed through a second slit and monitored by a light detector. When the etalon and the grating are tuned to the same precise wavelength a slit function is defined which is extremely narrow such as about 0.034 pm (FWHM) and about 0.091 pm (95 percent integral). The bandwidth of a laser beam can be measured very accurately by a directing portion of the laser beam into the insulator and scanning the laser wavelength over a range which includes the monochromator slit wavelength. In a second embodiment the second slit and the light detector is replaced by a photodiod array and the bandwidth of a laser beam is determined by analyzing a set of scan data from the photodiode array. Alternately, the laser wavelength can be fixed near the middle of the spectrum range of the grating spectrometer, and the etalon can be scanned.

摘要： An implantable brachytherapy device includes a biocompatible outer capsule containing a radiation shielding element and a radioactive isotope between the shielding element and the wall of the outer capsule. When the device is at body temperature, radiation is emitted by the isotope through the wall of the outer capsule. When a predetermined amount of energy is applied to the device, the shielding element is adapted to at least partially surround the isotope, and thereby at least partially prevent the transmission of radiation through the outer capsule.

摘要： A portable, self-contained, electronic radioscopic imaging system uses a pulsed X-ray source, a remote X-ray sensor, and a self-contained, display and controller unit to produce, store, and/or display digital radioscopic images of an object under investigation. The pulsed X-ray source transmits a burst of narrow pulses of X-rays at the object being investigated at a low repetition rate. The X-ray sensor utilizes an X-ray scintillating screen in combination with either an integrating CCD camera, or an active matrix of thin film transistors and sample-and-hold photodiodes, to produce an integrated signal representative of the accumulated number of flashes of radiation (X-ray pulses that pass through the object) that are sensed in a given pixel area of the scintillating screen. The self-contained display and controller unit utilizes digital signal processing within an enhanced portable computer, including a flat solid state display panel and associated drive circuitry, in order to display the full dynamic range and resolution of the sensor. A modem allows the digitized image to be sent to a remote location where the exact same image can be recreated for analysis by off-site experts.
