摘要： A system for determining a signature frequency of a photonic device includes a reference cell that receives a first light beam of a plurality of light beams. Based on a predetermined characteristic of the reference cell, the reference cell produces a first identifiable output indicative of a reference frequency in response to light in the first light beam having a particular frequency. A photonic device receives a second light beam of the plurality of light beams, and produces a second identifiable output in response to light in the second light beam having a frequency at the signature frequency. A computing device uses electrical signals representative of the first and second identifiable outputs to determine the signature frequency of the photonic device. A light source may emit a light beam having a controlled change of frequency and an optical splitter splits the light beam to produce the plurality of light beams.

摘要： Some systems include an acoustic sensor array configured to receive acoustic signals, an electromagnetic imaging tool configured to receive electromagnetic radiation, a user interface, a display, and a processor. The processor can receive electromagnetic data from the electromagnetic imaging tool and acoustic data from the acoustic sensor array. The processor can generate acoustic image data of the scene based on the received acoustic data, generate a display image comprising combined acoustic image data and electromagnetic image data, and present the display image on the display. The processor can receive an annotation input from the user interface and update the display image based on the received annotation input. The processor can be configured to determine one or more acoustic parameters associated with the received acoustic signal and determine a criticality associated with the acoustic signal. A user can annotated the display image with determined criticality information or other determined information.

摘要： Thermal imaging systems can include an infrared camera module (200), a user interface (208), a processor (222), and a memory. The memory can include instructions to cause the processor (222) to perform a method upon a detected actuation from the user interface (208). The method can include performing a non-uniformity correction (1702) to reduce or eliminate fixed pattern noise from infrared image data from the infrared camera module (200). The method can include capturing infrared images (1704) at a plurality of times and register the captured images via a stabilization process (1706). The registered, non-uniformity corrected images can be used to perform a gas imaging process (1700). A processor (222) can be configured to compare an apparent background temperature in each of a plurality of regions of infrared image data to a target gas temperature. The processor (222) can determine if such regions lack sufficient contrast to reliably observe the target gas.

摘要： A radio frequency (RF) imaging device comprises an optical position sensor, an RF sensor assembly, a processor, and a memory. The optical position sensor captures an optical image of a field of view and outputs data representing the optical image. The RF sensor assembly is disposed at a first position and receives an RF signal for capturing an RF image of a portion of a space disposed behind a surface at the first position and outputs data representing the RF signal. The processor receives the data representing the optical image and the RF signal, and determines that an optical signature of a reference marker is present in the optical image. If the optical signature is present in the optical image, the processor defines the first position of the RF assembly as a reference position. The memory stores the data representing the RF signal in association with the reference position.

摘要： Systems and methods can be used for analyzing image data to determine an amount of vibration and/or misalignment in an object under analysis. Image distortion present in the image data due to vibration and/or misalignment of the object during operation can be detected automatically or manually, and can be used to determine an amount of vibration and/or misalignment present. The determined amount of vibration and/or misalignment can be used to determine alignment calibration parameters for inputting into an alignment tool to facilitate alignment of the object. Various steps in determining the image distortion and/or the alignment calibration parameters can be performed using single components or can be spread across multiple components in a system.

摘要： A thermal imaging camera may be used to capture a visible-light (VL) image and an infrared (IR) image. In some examples, the camera includes a range imaging camera module that captures the VL and an infrared camera module that captures the IR image. In such examples, the VL image may include a plurality of different portions that each correspond to a different portion of the scene and distance-to-target data associated with each of the different portions of the scene. The camera may align each of the plurality of different portions of the VL image based on the distance-to-target data associated with corresponding portions of the scene so as to correct a parallax error between the VL image and the IR image. The camera may then concurrently display the VL image in alignment with the IR image.

摘要： An acoustic analysis system includes an acoustic sensor array that receives acoustic signals from a target scene and outputs acoustic data to a processor. The processor generates acoustic image data of the target scene, partitions the acoustic image data into a plurality of acoustic image portions including first and second acoustic image portions, wherein the first acoustic image portion is different than the second acoustic image portion. The processor generates a display image by visually contrasting acoustic image data within the first acoustic image portion satisfying a first set of predefined acoustic criteria from acoustic image data within the first acoustic image portion not satisfying the first set of predefined acoustic criteria, and visually contrasting acoustic image data within the second acoustic image portion satisfying a second set of predefined acoustic criteria from acoustic image data within the second acoustic image portion not satisfying the second set of predefined acoustic criteria.
