摘要： A method and apparatus are provided for performing non-invasive measurements, and in particular in vivo non-invasive measurements of the total body content of a particular element, or of the content of such elemetn in a particular body area, by use of resonant gamma ray detection. More particularly, gamma rays are generated at the resonant gamma absorption energy level for the element on which measurements are to be made and are passed through the portion of the patient's body for which measurements are to be made. Detected gamma rays passing through the patient's body may be utilized as an indication of the content of such element. The effect of non resonant gamma absorption may be subtracted by also passing gamma rays of non-resonant absorption energy through the same body part and utilizing detected gamma rays at this energy passing through the body to determine the non-resonant absorptions.

摘要： In accordance with one embodiment of the present invention, a controlling laser beam at a first wavelength is introduced into an interferometer such that one half of it contains the aberrations of the laser beam to be controlled and the other half is and remains undistorted. The aforementioned two halves of the controlling laser beam are combined at the output of the interferometer and then, together with the laser beam to be controlled at a second wavelength is introduced collinearly into a gas cell or phase corrector. Upon combination or interference of the two halves of the controlling laser beam the phase-front aberrations are translated to intensity modulations across the cross section of the beam. Utilizing nonlinear dispersion in the gas cell in accordance with the invention, the intensity modulations across the controlling laser beam are transformed by nonlinear dispersion interaction into appropriate refractive index variations at the second wavelength which in turn causes corresponding phase changes across the phase front of the controlled laser beam. Adjustment of path length in the interferometer permits compensation of the aberrations in the controlled laser beam.
摘要翻译：根据本发明的一个实施例，将第一波长的控制激光束引入到干涉仪中，使得其中的一半包含待控制的激光束的像差，另一半的像差保持不变。将上述控制激光束的两半组合在干涉仪的输出处，然后与被控制在第二波长处的激光束一起共线地引入气室或相位校正器中。在控制激光束的两个半部的组合或干涉下，相位前像差被转换成穿过横截面的强度调制。利用根据本发明的气体电池中的非线性色散，跨越控制激光束的强度调制被非线性色散相互作用转变成在第二波长处的合适的折射率变化，这反过来又导致横跨控制的相位前沿的相应的相位变化激光束。干涉仪中路径长度的调整可以补偿受控激光束的像差。

摘要： A method of providing laser controlled real-time optics and optic systems for a laser beam or beams utilizing near resonance nonlinear dispersion in a collision dominated gaseous medium. Refractive optical elements may be provided that function as spherical or curved reflectors and refractive lens or prisms for expanding or contracting a laser beam or beams as well as providing gratings for providing partial or total reflection or deflection of a laser beam. The generation of a grating in accordance with the invention permits total deflection of large cross-section and powerful laser beams by the investment of a moderate amount of power. Real-time color holographic displays may also be provided and phase front aberrations caused by a laser amplifier may also be corrected.
