Asheville, NC -March 16, 2006 - Amid growing fears of bird flu pandemic and the threat of the virulent strain spreading through human-to-human transmission, Wahl Instruments Inc. announces the Wahl Fever Alert Imaging System designed specifically for mass screening of public areas like air/sea ports, rail/subway stations and large industrial manufacturing facilities, for individuals with elevated body temperatures. An increased body temperature, or fever, from the "normal" (98.6 [degrees]F or 37[degrees]C) is often a good clinical indication of possible infection.

The easy to operate Wahl Fever Alert Imaging System produces a real-time thermal picture of facial skin surface temperature as each person passes by the camera and with its special software triggers both a visual and audible alarm if the temperature reading is above a user predefined threshold. The system also includes a temperature reference source that allows the camera to be precisely calibrated prior to and during use.

The small Wahl Fever Alert Imaging System is based on the latest detector technology and can resolve surface temperature differences of [+ or -]0.5* C and when combined with its software and temperature reference source makes it an efficient and very affordable screening solution.

Miniature Thermal Imaging Cameras for Firefighting Applications

The ability to detect the temperature differences of objects is vitally important to firefighters, who must often open doors that lead to fires and identify the seat and extension of a fire quickly and reliably. This palm-sized thermal imaging camera (TIC), the Omega(TM), has a very wide scene dynamic range. This is critical because the camera can be pointed in the direction of a very hot fire, yet still produces a useable image of the colder surroundings or personnel without saturation.

Smoke has a large component of micron-sized carbon soot particles in it, making it very absorbing in the visible-light waveband. However, when the particle size is significantly smaller than the wavelength of light used by a sensor, the scattering is greatly reduced, making it possible to see through smoke.

The infrared sensor, based on vanadium oxide microbolometer technology, is a 160 × 128 pixel focal plane array (FPA) that images in the 7-14 micron (longwave IR) waveband and does not require ternperature stabilization, thus eliminating the thermoelectric cooler (TEC) found in other microbolometer cameras. Proprietary read-out circuitry in the Omega FPA and novel non-uniformity correction algorithms make operation without a TEC possible. Also, the camera package utilizes a very specialized flex board technology that folds up like an accordion inside the metal camera case. This technology eliminates many connectors that would add size and cost and reduce reliability.

A version of this camera has been successfully integrated into the Evolution® 5000 TIC fire service tool manufactured by Mine Safety Appliances (MSA) in Pittsburgh, PA (Figure 1). The Omega(TM) provides the Evolution® 5000 with 14-bit scene dynamic range, and uses a non-linear histogram AGC algorithm called SmartScene(TM) to map the 14-bit range to an 8-bit analog video display. It also has two gain states, which are automatically selected according to the percentage of pixels in the image that go above or below a threshold value. This enables it to operate in the extreme environments that firelighters regularly encounter, such as a dark wet basement and a burning room.

The Evolution® 5000 takes advantage of the Omega camera's Isotherm display option, which allows users to tint every pixel at a certain temperature or within a temperature range a specific color. Figure 2 shows an image of a firefighter in a burning room. The yellow pixels correspond to temperatures above 842 0F, and the red pixels to temperatures above 887 °F. The scene temperature, measured by the spot meter denoted by the green dot in the center of the image, is read out on the bar indicator on the right of the image. The bar indicator changes color to indicate high or low gain mode. The "L" indicator tells the user that the TIC is in low sensitivity or "firefighting" mode. This lower sensitivity mode extends the dynamic range of the TlC and is particularly useful in fire service where scene temperatures can be extremely wide.

Precise camera focusing and positioning is accomplished using the vertical focus stage. Areas of interest on a device can be quickly and accurately positioned within the camera's field-of-view using the XY stage. The thermal stage provides both heating and cooling for precise device temperature control in order to locate short circuits and to compensate for pixel emissivity variations.

Thermal Imaging Camera works with PC

Real-time, radiometric Model 220 uses PC for camera control, image display, image analysis, and storage. Based on uncooled microbolometer technology, camera provides temperature measurements from 0-140*C with thermal stability of less than 1*C over 1 year. Images are 320 x 240 pixels and stored as TIFF files that retain all thermal characteristics. WinTES2 software provides range of analysis tools and accepts image files from other camera formats.

Lake Oswego, Oregon- Dec. 30, 2004 - Compix Incorporated, a manufacturer of low cost thermal analysis tools, today announced the Compix 220 realtime, thermal measurement camera and WinTES2 thermal imaging software. The 220 expands the Compix line of thermal measurement systems while adhering to proven approach of mating the camera and software with the power of the PC. The camera uses a personal computer for camera control, image display, image analysis and storage. With the Compix 220, WinTES2 and a personal computer (PC) the user has a powerful tool for analyzing thermal performance of electronic designs, or manufacturing processes.

Based on uncooled microbolometer technology the 220 provides temperature measurements from 0* to 140*C with thermal stability of <1*c>

Images are 320 x 240 pixels (interpolated from 160 x 120). Temperature sensitivity is greater than 0.1* C. This assures that small temperature differences will be detected and that small features can be measured. Images are stored as TIFF files that retain all thermal characteristics.

The highly flexible WinTES2 software offers a wide selection of "plug-in" modules to allow the camera to be adapted to new and changing measurement applications.

The 220 and WinTES2 software are available. Shipping capability is 2 weeks ARO

Thermal Imaging Cameras Cheetah

Cheetah imaging system

XenICs

XenICs has released its high-end, power PC-based, high-speed imaging system Cheetah, which is an InGaAs focal-plane array camera that covers the standard SWIR (short-wave infrared) wavelength area 0.9 to 1.7µm - with all control and communications circuitry in one housing.

Cheetah offers a high resolution of 640 x 512 pixels at a maximum full frame rate of 1,730Hz. In a reduced region-of-interest mode, more than 100,000fps is feasible.

The Cheetah features a 640 x 512 pixel InGaAs array. This InGaAs detector features a new XenICs ROIC (read-out integrated circuit) optimised for high speed with 16 outputs and a 40MHz pixel rate. The Cheetah camera includes a graphical user interface that provides direct access to various camera settings, such as exposure time, region-of-interest and gain.

A fast and easy non-uniformity correction (two-point) procedure is also available. The camera's power PC allows for a data interface based on the TCP/IP Gigabit Ethernet protocol and more advanced correction procedures. Alternatively, a CameraLink data interface is also foreseen by the company.

The Cheetah camera can be operated in two modes:
1. Stand-alone, using the on-board memory (up to 16 GB) for extremely fast data acquisition. At 1,730 full frames per second, recording time is limited to 15 seconds;

2. Continuous streaming, using a PC and the CameraLink interface for continuous data streaming (frame rate is limited by the CameraLink interface speed).

The Cheetah digital camera is equipped with 14-bit ADCs and is operated from a single 12 V/5 A power supply (included in the delivery). A C-mount fixture allows the use of all standard optical lenses. A medium-speed version of the Cheetah (400fps maximum) will also be available.
