摘要： A spectral bandpass filter with a sharp angle independent absorption edge for reducing optical noise is used in conjunction with a known atomic resonance filter-detector or QLORD detector such as described in U.S. Pat. No. 4,292,526. The QLORD detector comprises two spectral bandpass filters enclosing or sandwiching a chamber containing atomic vapor. In accordance with the present invention, between the high-pass filter and the atomic vapor is placed a strip of volume absorbing filter material. The high pass filter has already admitted light which can be absorbed by the atomic vapor thereby excluding that incoming light which is in the spectral range of the light readmitted by radiative decay. The volume absorbing material then makes the further attenuative selection between the various sets of hyperfine lines. The line or lines which absorb the incoming signals are not attenuated; and the incoming light present as optical noise which could be absorbed by other hyperfine lines is strongly attenuated thereby minimizing that source of noise. In a preferred embodiment of the present invention, a volume filter is inserted to remove one of a set of two hyperfine lines, with optical transmission taking place through the other set of lines.

摘要： A two wavelength lidar imaging system for underwater applications is presented which employs image subtraction. More specifically, a two wavelength lidar system is presented wherein two substantially simultaneously timed laser pulses of different wavelengths are emitted and are expanded by optics to illuminate the water below. A framing camera is then gated to receive light reflected or scattered back from the water. The light backscattered is filtered through narrow pass filters before it is recorded at the gated cameras. A specific application is disclosed in which the lidar imaging system is used to detect the passage of internal waves or other anomalies appearing in the ocean.

摘要： An imaging UV/visible fluorosensing and Raman lidar system comprises an optical sensor for simultaneously measuring temporally, spatially and spectrally resolved laser backscatter from on the land, on or beneath the surface of bodies of water and in the atmosphere and utilizes "active" interrogation or "passive" interrogation for remotely and non-destructively probing the spectrally-dependent optical properties of a scene. In the "active" mode, the optical sensor of this invention comprises a transmitter (preferably a tunable solid state laser) which emits pulses of coherent light through a variable or adjustable field-of-view telescope whereupon the light pulses are then propagated towards a scene (e.g., land, sea or atmosphere). Thereafter, laser backscatter is collected by a second variable field-of-view telescope and directed to an imaging system and spectrally dispersive optical subsystem.

摘要： An imaging lidar system is presented which is adapted to decrease the backscattering at the receiver when a target is viewed in reflection and to increase the backscattered reflection when the target is viewed in obscuration by operating the airborne lidar imaging system bistatically in the former case, and monostatically in the latter case. In accordance with a first embodiment of the present invention, a retractible prism and remote reflecting mirror are used to direct the laser transmitter beam downward. The reflecting mirror is offset so that there is a finite angle between the transmitter optical path and the path of the light reflected back into the CCD framing camera. The angle can be varied by moving the reflecting mirror along a track or rail with the appropriate adjustment to the mirror so that the transmitter beam is completely captured and directed downward to illuminate the area viewed by the camera. In a second embodiment of the present invention, the camera is placed on runners and displaced from the transmitter beam. A control is inserted so that the transmitter optics are directed to the area imaged by the camera.

摘要： The present invention uses tunable and fixed frequency lasers as an optical light source in underwater communications systems. This invention provides a high energy, short pulse length laser output which is tunable to or set at a desired wavelength. The tuning is used for performance optimization of the communications systems. An example of performance optimization is the tuning to or setting of the laser at the so-called Jerlov minimum, which is dependent upon the optical characteristics of the particular water used. The system described herein is used as an optical communications downlink employing one or more atomic resonance filter detectors. This invention has the effect of significantly improving the optical signal to noise ratio.

摘要： A method is provided in which the pulse stretching effects of radiation trapping can be minimized in atomic resonance filter detectors or QLORD filter detectors of the type described in U.S. Pat. No. 4,292,526. The QLORD detector of this invention which consists of two spectral bandpass filters, one each located on either side of a transparent cell containing an alkali metal vapor (preferably cesium vapor), and responds to an incoming pulse in the visible part of the spectrum of light (actually 420 to 480 nm), emitting a pulse of infrared light. If the transparent cell contains alkali metal vapor only, the infrared light pulse will be stretched, because of resonant trapping within the alkali metal vapor. However, in accordance with the present invention, an inert buffer gas (namely helium) is added to the alkali metal vapor. This buffer gas allows the rapid leakage of infrared light photons from the wings of the energy spectrum, and hence a more rapid response to the incoming pulse. The present invention is particularly useful in overcoming "false alarms" such as bioluminescence signals when pulse stretching and external noise sources are superimposed, and when a rapid pulse repetition rate is useful.
摘要翻译： 提供了一种方法，其中在美国专利中描述的类型的原子共振滤波器检测器或QLORD滤波器检测器中可以最小化辐射捕获的脉冲拉伸效应。 第4,292,526号。 本发明的QLORD检测器由两个光谱带通滤光器组成，每个光谱带通滤光器分别位于含有碱金属蒸气（优选铯蒸气）的透明电池的两侧，并且响应于光谱的可见部分中的输入脉冲 （实际上是420〜480nm），发出红外光脉冲。 如果透明电池仅含有碱金属蒸气，则由于在碱金属蒸气中的共振捕获，红外光脉冲将被拉伸。 然而，根据本发明，向碱金属蒸气中加入惰性缓冲气体（即氦气）。 这种缓冲气体允许红外光子从能量谱的翅膀快速泄漏，因此对输入脉冲的响应更快。 本发明在克服脉冲拉伸和外部噪声源叠加时的生物发光信号以及快速脉冲重复率有用时特别有用。
