    ATRs generally have to detect and recognize objects at much longer ranges than commercial systems. Enemy detection and recognition are noncooperative processes. Although a future car might have a LADAR, radar, or FLIR sensor, it won't have one that can produce high-quality data from a 20,ft range. model of an aircraft [Figure 6]. The model is painted a flat black and heated to about 40C. The intensity I image shows the temperature distribution over the target and is identical to an image from a FLIR sensor. The P image shows significant polarization (bright pixels) over the surfacesCited by: 5.

Now we will compare the performance of a traditional CCD sensor versus a modern CMOS sensor in low light imaging conditions and in a scene with a wide range of lighting conditions. In the previous section we showed that a camera with the Sony ICX, a ½’’ VGA CCD, performs better in low light conditions than a camera with the Sony ICX

    The FLIR identiFINDER S is an autonomous sensor that delivers real-time radiation detection and identification. It detects the presence or movement of radioactive material across borders, into buildings, at large public gatherings, and events. The INT-POL is an integrated pair of balanced detectors that are used to analyze the S and P States of Polarization (SOP) of two input signals independently. This compact system is designed for polarization sensitive optical coherence tomography (OCT) applications, but it can be used in any app.

Results showed that there is an improvement in maximum range of the sensor for detection, recognition, and identification tasks when a horizontal filter is included, provided that the target does not have a negative degree of polarization.

For detection task the improvements were found to be %, 65%, and % when the target has 0%, +2%, and +8% degree of polarization Author: Mehmet Yildirim.

Abstract: A complete polarization image sensor composed of a 60 by 20 pixel array with on-chip analog processing and integrated with pixel-pitch polymer polarization filter is presented.

The image sensor, fabricated in m CMOS process, computes the first three Stokes parameters at the focal plane at 30fps with 15mW power consumption. Combining Polarization and Color. The IMXMYR sensor adds a color filter array to the sensor below the polarizing filters.

This sensor uses a unique quad-Bayer pattern which prioritizes spatial resolution of the polarization domain over spatial resolution of color information.

The identiFINDER R-series are easy-to-use handheld instruments that quickly detect, locate and identify radiation sources. These products contain on-board Bluetooth, web server and GPS technologies (select models) and produce rapid visible, audible and tactile alerts that expedite response measures.

Here we give context to the Special Issue on “Detection and Tracking of Targets in Forward-Looking InfraRed (FLIR) Imagery” in Sensors. We start with an introduction to the role of infrared images in today’s vision-based applications, by outlining the specific challenges that characterize detection and tracking in FLIR images.

2) I demonstrated that spin-image-based detection and recognition is feasible for terrain data collected in the field with a sensor that may be used in a tactical situation and 3) I demonstrated.

This VGA format sensor is designed for a variety of applications, including hyperspectral instrumentation, silicon inspection, electro-optical payloads, art restoration, counterfeit detection, and portable systems.

The ISC SWIR sensor provides outstanding image quality and performance over a wide range of imaging and light level conditions. Circular polarized light is rare in nature 8 and thus the discussion in this chapter will be limited to the detection and analysis of linear polarization.

Polarization of light from an unpolarized beam. A linearly polarized beam is obtained from an unpolarized beam by removing all waves from the beam except those the electrical field vectors of which oscillate in a single by: 2.

In a second set of experiments, the SNR model for FLIR employed in [25], [26] based on the mean object and background pixel intensity was used to estimate the operating SNR of dB of the FLIR.

The polarization information in real time can be obtained with a photodetector array, such as a CMOS or a CCD sensor array and a single or multi-axis micropolarizer filter array coupled to it.

The polarization filter can be either externally coupled, or an organic micro-polarizer or a metallic wire grid micro-polarizer. The FLIR VT8-Series are high-quality voltage, continuity, and current testers.

They feature an optimized, open-jaw design that can fit into tight spaces and reliably measure large-diameter cables. The VT carries a CAT III V/CAT IV V safety rating and a A/ V measuring range, while the VT carries a CAT III V/CAT IV.

Range sensing in general is briefly reviewed, followed by a description of the Oxford/NEL range finder, a sensor mounted on the Oxford AGV for use in object recognition and acquisition tasks.FLIR VP Non-Contact Voltage Detector + Worklight.

The FLIR VP50 is a tough, CAT IV-rated Non-Contact Voltage Detector featuring a combination of alerts - tactile vibration and red LED alarms, a powerful LED flashlight, and versatile voltage sensitivities. Resolution required for Recognition, Detection, Identification depends on the type of camera.

By Bob Mesnik. There is some confusion in the industry about how much camera resolution is required to detect an object, recognize the type of object, or identify exactly what or who it is. The criteria are different between thermal and optical cameras.
