Abstract: This invention is directed to a spectrum analyzer system which is laser-driven and which includes a standard Bragg cell and a standard photo-diode array as the output detector. In this system, the Bragg cell is driven by a bandwidth expansion circuit which receives the typical R.F. input signal, supplies it to a variable center frequency filter or to a bank of filters which then down-converts the signal and supplies the signal to a real time signal storage memory at a first signal rate. The signals are retrieved from the memory at a second, much greater signal rate, up-converted and supplied to the Bragg cell to affect the operation thereof in the usual fashion. This time base compression circuit has the effect of producing an improved optical spectrum analyzer with expanded frequency resolution.

Abstract: A light-collecting reflector for use with a source of light comprises a main reflector having a central parabolic reflecting surface and an outer ellipsoidal reflecting surface surrounding the central surface. The main reflector is adapted to have a source of light placed along its central axis. A secondary reflector having a reflecting surface facing the reflector surfaces of the main reflector and having an open central portion to allow light to pass therethrough, is positioned in front of the main reflector so that light striking the reflector surface of the secondary reflector is reflected back toward the reflecting surfaces of the main reflector. The reflecting surface of the secondary reflector is arcuate with radii that emanate from a circle which is concentric with the center axis of the main reflector.

Abstract: A system for capturing and analyzing images of body features to identify treatments has a base unit with a processor and a display and an image management software component for presenting on the display a user interface to prompt a user to capture images in preselected locations on a body and to receive captured image data. The system has at least two light sources under control of the user interface that provide light following first and second light paths from the respective light sources to the plane of an imaging station, each light path having a significant portion of its light on the plane of the imaging station at a grazing angle of about ten to about thirty degrees. The first and second light paths when projected onto the plane of the imaging station intersect at an angle of at least sixty degrees. An image sensor receives light from the light sources that is reflected from the surface of a body feature located at the imaging station and produces pixel image data representing the body feature. A rating software component receives the pixel image data from the image sensor and is configured to mimic the judgment of a dermatologist to provide a rating vector representing the condition of three or more attributes of the body feature represented by the pixel image data.

Abstract: An acousto-optic spectrum analyzer in which the dynamic range is effectively extended by detecting the frequency bands wherein the photo-detectors are saturated and providing a filter to suppress those frequencies. With this pre-filter, the entire spectrum appears to be within the dynamic range of the photo detectors. The actual spectrum can be reconstructed using the response of the suppression filter and the photo detector output.

Abstract: A shutter system for stage-lighting spotlights includes a housing having a fixed framing gate therein which has an opening therethrough for the passage of light. Two sets of opposing shutter blades are sandwiched, one on each side of the framing gate, between the framing gate and one of a pair of pressure plates which have means urging them toward the framing gate. Each shutter blade has a neck portion which extends through a slot in the housing and which serves as a handle to which pressure may be applied to move the shutter blade. The blades are normally held in place by the action of the pressure plates against the blades and framing gate.

Abstract: A microscope system for observing moving particles makes use of a television camera for producing a continuing series of images of such particles. A source of light pulses illuminate the particles with each pulse for a period short enough to stop their movement for the camera. The light source and camera are synchronized so that the light pulses occur only between times that the camera produces image-information signals. For obtaining particle size measurements, a single light pulse during a time that the camera is not producing image-information signals is sufficient. For obtaining paticle velocity measurements, two light pulses are required so that a "double exposure" occurs at the camera during a time that the camera is not producing image-information signals.

Abstract: An acoustic signal is launched as a surface acoustic wave (SAW) by a hyperbolically tapered transducer and then reflected into a bulk acoustic wave (BAW) by a tapered reflector. At each frequency the tapered reflector must satisfy the phase match conditions between the SAW and BAW as defined by their wave vectors. Let k.sub.B be the projection of the BAW wave vector on the surface, and let k.sub.S be the wave vector of the SAW. Then, if k.sub.G is defined to be the wave vector of the grid, i.e., k.sub.G =2.pi./d, where d is the periodicity of the reflecting strips at the frequency under consideration, the phase match condition is k.sub.G =k.sub.B -k.sub.S. A reflector designed to satisfy this condition will reflect the SAW into a BAW at any desired angle (as specified by k.sub.B). The laser beam is then Bragg scattered by the BAW in the usual manner. The advantage of this scheme is that the tapered transducer separates the acoustic signals spatially so no intermodulation products are formed. Furthermore, the tapered transducers are able to handle higher power levels than other transducers so high acoustic signals can, in fact, be used. An additional improvement in Bragg scattering efficiency can be achieved by curving the reflective array in such a way as to direct the BAW so that the Bragg angle for optimum scattering efficiency is exactly met for all frequencies. This insures that the device can be used over a broad bandwidth without a fall off in the Bragg scattering efficiency.
Abstract translation: 声信号通过双曲锥形换能器作为表面声波（SAW）发射，然后通过锥形反射器反射成体声波（BAW）。 在每个频率下，锥形反射器必须满足由其波矢定义的SAW和BAW之间的相位匹配条件。 令kB是BAW波矢量在表面上的投影，并使kS成为SAW的波矢。 然后，如果将kG定义为网格的波矢，即kG =2π/ d，其中d是所考虑的频率处的反射条的周期性，则相位匹配条件为kG = kB-kS。 设计成满足该条件的反射器将以任何所需的角度（如由kB指定）将SAW反射到BAW中。 然后激光束以通常的方式由BAW散射。 该方案的优点是锥形换能器在空间上分离声信号，因此不会形成互调产物。 此外，锥形换能器能够处理比其他换能器更高的功率水平，因此实际上可以使用高的声信号。 可以通过以这样的方式弯曲反射阵列来实现布拉格散射效率的另外的改进，以引导BAW，使得针对所有频率精确地满足用于最佳散射效率的布拉格角。 这确保了器件可以在宽带宽上使用，而不会在布拉格散射效率下脱落。
