When was flir invented

In yet another example, such a system may be implemented as a spotlight. Filed: March 13, Publication date: May 28, Abstract: This invention generally relates to optical devices that can collect and detect signal emissions effectively while allowing the excitation light path and the sample flow path to coexist non-obstructively in a compact format.

More specifically, this invention relates to a compact device having a multilayer coating on the structure surface and a wave guiding structure. In the device, using the surface plasmon coupling effect, the majority of the optical emission from the emitter on top of the multilayer coating is distributed toward the wave guiding structure.

The wave guiding structure then further directs on signal to the detector with a high efficiency. Filed: February 14, Publication date: March 6, Inventor: Flir Systems, Inc. Abstract: Various techniques are disclosed for providing systems and methods for orienting one or more lenses or other optical elements in a lens sleeve.

For example, a system may include a lens sleeve defining an interior lens cavity. A plurality of lens positioning features extend from the lens sleeve adjacent the interior lens cavity.

A first lens is secured in the lens cavity at a first position relative to the lens sleeve. A first set of the lens positioning features are located at a second position relative to the lens sleeve, and a second set of the lens positioning features are located at a third position relative to the lens sleeve. A second lens engages either the first set or the second set of the plurality of lens positioning features depending on a desired distance between the first lens and the second lens.

Publication date: October 17, Abstract: A referencing method for an optical biosensor system using a single sensing region is provided. The method involves limiting the ligand immobilized in a single sensing region to only a portion thereof.

In one embodiment, this is accomplished by selectively deactivating a portion of the sensing surface to prevent immobilization of ligand to that portion. As a result, a reference response can be recorded in the same sensing region as a molecular interaction response. Thus, the bulk refractive index can be accurately accounted for in measuring the kinetics of a molecular interaction.

Publication date: July 4, Abstract: Infrared imaging systems and methods disclosed herein, in accordance with one or more embodiments, provide for detecting petroleum in an infrared image.

The detection involves the evaluation of local background model likelihoods in light of extracted pixel features as well as the evaluation of a global outlier model in light of extracted pixel features.

Those pixels having a low likelihood for both their local background model as well as the outlier model are identified as corresponding to oil-contaminated water within the infrared image. Filed: February 7, Publication date: June 13, Abstract: Various techniques are provided to perform flat field correction for infrared cameras.

In one example, a method of calibrating an infrared camera includes calibrating a focal plane array FPA of the infrared camera to an external scene to determine a set of flat field correction values associated with a first optical path from the external scene to the FPA. The method also includes estimating a temperature difference between the FPA and a component of the infrared camera that is in proximity to the first optical path. The method also includes determining supplemental flat field correction values based on, at least in part, the first set of flat field correction values, where the supplemental flat field correction values are adjusted based on the estimated temperature difference before being applied to thermal image data obtained with the infrared camera.

The method also includes storing the supplemental flat field correction values. Infrared Energy Detection An infrared camera is a non-contact device that detects infrared energy heat and converts it into an electronic signal, which is then processed to produce a thermal image on a video monitor and perform temperature calculations.

Can FLIR see through walls? No, thermal cameras cannot see through walls, at least not like in the movies. Walls are generally thick enough—and insulated enough—to block any infrared radiation from the other side. If you point a thermal camera at a wall, it will detect heat from the wall , not what's behind it. Does FLIR work in daylight? You can defeat traditional night vision device but you simply cannot hide completely from thermal infrared imaging technology. That is one of the benefits of thermal infrared imaging technology it can be used in daylight or complete darkness, it is totally independent of visible light.

What can FLIR see? How much does a FLIR cost? Is thermal imaging better than night vision? While thermal is better for detection, it is definitely pricier than night vision.

Thermal imaging is newer and more costly technology to manufacture. Night vision has been around since WWII and is much more available and affordable.

Can thermal imaging see through concrete? The short answer to this question is, unfortunately no. This is so because thermal imaging relies on detecting the infrared wavelengths and temperature that is emitted from the surface of the object itself. The thermal imaging devices cannot see through thicker objects like concrete for example.

What can police helicopters see? Yes, people in helicopters can see inside your house, through the windows.
