摘要： A fluorescence radiation detector of the Fraunhofer line discriminator type. A sky telescope and an earth telescope each form radiation beams which are directed to a single optical chopper. The chopper sequentially directs each beam through a single Fabry-Perot filter centered at the Fraunhofer line and a single neutral density filter. The chopped segments are recombined to form a beam containing A, B, C, and D portions in time sequence where: A the direct solar intensity within the continuum; B the direct solar intensity inside the selected Fraunhofer line; C the reflected solar intensity inside the selected Fraunhofer line; and D the reflected solar intensity in the continuum. A single photomultiplier tube with a blocking filter in front receives the beam and produces corresponding sequential electrical pulses which are electronically processed to yield fluorescence (p) from the equation

摘要： To derive sunlight induced fluorescence from radiance measurements, a first radiance measurement is taken inside an atmospheric absorption band, and an additional radiance measurement is taken outside of the atmospheric absorption band. Images of sunlight-induced fluorescence are obtained with the aid of a camera. Air- or spaceborne spectrometers and image points on non-fluorescent objects are used to determine the radiance conditions on the ground and the influence of the atmosphere.

摘要： An apparatus for determining the fluorescence of materials in a scene which includes optical means to collect radiation from the scene. Means are provided to divide the collected radiation into first and second beam paths. The first beam path traverses a first filter centered on a Fraunhofer line and having a passband which extends into the solar continuum on either side of the Fraunhofer line. The second beam path traverses the first filter and a second filter, also centered on the Fraunhofer line, with a passband on the order of half the bandwidth, at half-depth, of the Fraunhofer line. Means are provided to image the first and second beams onto first and second detector arrays, respectively. The image on the first detector array is registered with the image on the second detector array. Co-adding means are provided whereby successive detector pixels at successive time intervals corresponding to a single point on the ground are added and averaged. The time interval is a function of a constant clock rate and a V/H signal. A single detector is provided to detect the intensity of direct solar radiation outside the Fraunhofer line. A processor compares the value of intensity from the co-added point on the ground from the first and second detector arrays and the single detector to determine fluorescence at each point on the ground in the scene being viewed. In another form, where an optical laser illuminator is employed, the first beam path traverses a first filter which only allows the laser radiation to pass. The second beam path has a passband which passes the emission spectrum of a material excited by the laser radiation.

摘要： A method and apparatus for detecting fluorescence from sunlit plants is based on spectral line discrimination using the A-band and B-band absorption of atmospheric oxygen. Light from a plant including scattered sunlight and the fluorescence from chlorophyll is passed through a chopper into a cell containing low-pressure, high-purity oxygen. A-band or B-band wavelengths present in the light are absorbed by the oxygen in the cell. When the chopper is closed, the absorbed light is remitted as fluorescence into a detector. The intensity of the fluorescence from the oxygen is proportional to the intensity of fluorescence from the plant.

摘要： Apparatus is provided to sense and measure solar-induced luminescence, as well as reflectance, within the field of view of a target window for receiving a composite ray of light from the target. A first filter within the path of the composite ray of light transmits a first narrowband component thereof, including a predetermined Fraunhofer Line frequency, to a first sensor. A second narrowband component thereof, proximate the Fraunhofer Line frequency, is directed to a second sensor such that ratios of the electromagnetic energy impinging, respectively, on the first and second sensors may be determined. A removable filter tray carrying the narrowband filters and fine tuning means is employed to facilitate the selection of the predetermined Fraunhofer Line frequency.

摘要： A radiometer for detecting and measuring components of luminescence and reflected light contained in a light beam from a target which included means for sensing the temperature of an optical filter in the radiometer and for adjusting the angular position of the mount which carries the filter in response to the sensed temperature to thereby retune the filter to its center frequency when changes in temperature occur. Longitudinal movement of an adjustment rod changes the angular position of the mount. A micrometer means manually moves the rod in one embodiment while a motor moves the rod in a second embodiment. The rod carries a means for sensing the longitudinal position of the rod (hence the rotational position of the mount) and generates a signal representative thereof. A means on the mount senses the temperature of the filter and generates a signal representative thereof. The temperature and position signals are compared by a processing circuitry which outputs an error signal if the position of the mount does not match a predetermined temperature signal. This error signal the (1) directly operates a control mechanism to move the adjustment rod which rotates the mount to a new angular position to retune the center frequency of the filter or (2) is fed to a visual indicator, which is brought back to a desired reference point by rotating the micrometer.
