Applications of SWIR Cameras
If you’re an art historian, you may be familiar with the applications of SWIR cameras. SWIR cameras can be used to view the details of pencil or charcoal drawings. These cameras allow art historians and artists to visually verify the authenticity valuable documents. Here are some examples. Listed below are some applications of SWIR cameras. These applications require a camera that is sensitive to infrared light.
Machine Vision Camera
Machine vision applications have many advantages due to the SWIR camera. Speed is one of the benefits. These cameras operate at standard video rates of 30 to 60 frames per second and can detect objects at speeds as high as ninety thousand lines per second. These cameras can record full 1024-pixel resolution at 12 bit. They are also remarkably cost-effective. Here are some of the most popular uses of SWIR cameras.
Vision systems are based on industrial machine vision cameras. Machine vision industries are evolving to keep up with the cost-effective and sophisticated machine vision industry. SWIR cameras are used in the glass industry to efficiently identify and reprocess rejected parts. In an industrial setting, SWIR cameras are able to detect the centroid energies of laser spots. The camera can detect the centroid energy and identify contaminated materials.
Another popular application of SWIR cameras is moisture detection. Water is transparent to visible light and absorbs strongly at wavelengths of 1450 to 1900 nm. The SWIR camera can detect moisture in coatings, detect fill levels of non-transparent containers, and measure the relative water content of plants. The SWIR camera can detect defects in silicon products as well as identify recycled plastics. In addition to these applications, SWIR cameras have optical coatings to improve image quality.
Swir InGaAs Camera
An SWIR InGaAs Camera is a great choice for many defense applications. The uncooled design of the camera is lightweight and sensitive to nightglow. Its high-resolution images can be used to detect laser designators and can be attached to covert eye-safe lasers. Several applications for SWIR imaging include target recognition and laser gated imaging. There are many benefits to the SWIR InGaAs camera.
Moisture detection is one of the most popular SWIR applications. While water is transparent to visible light, it absorbs strongly between 1450 and 1900 nm, producing an image that looks black. It is a useful tool to detect water. This allows it to identify areas of deficiency and areas of excess water. It can also be used to measure relative water content in plants, and can even detect damaged fruits.
An InGaAs camera is particularly effective in detecting defects and cracks on silicon. InGaAs cameras can penetrate in-vivo tissue and are therefore essential for moisture measurements, surface film distribution and material separation. A drawback of this imaging technology is its high dark noise, which is usually higher than one spectral wavelength. However, deep cooling reduces dark noise.
Silicon Inspection Camera
Traditionally, silicon surface inspection has been performed using CCD or CMOS cameras. These cameras can produce a wavelength response between 350 and 1000 nm. Deep-depleted silicon devices provide sufficient quantum efficiency for seeing the shortest wavelengths but require long integration times, and are not suitable for imaging intraband emissions of Si above 1100 nm. They are suitable for front-side inspection offline. Here are some advantages of Si-based cameras.
A spectroscopic camera can detect small defects and features a polarizer. The polarization of the lens allows for the camera to capture images under polarized light. This feature is important for the inspection of reflective surfaces. Another advantage of the camera is that it can be set up for single dies and silicon wafers. Another feature that distinguishes it from other cameras is its ESD-safe stand. A SWIR camera’s spectral resolution is three times greater than a standard camera.
A silicon inspection camera can detect defects in silicon wafers, solar-cell panels, and integrated circuits. This increases productivity and yields. The use of InGaAs cameras in silicon inspection applications is a growing trend. InGaAs cameras are especially useful for monitoring wafer bonding processes. It can detect defects in silicon, even when they’re hidden behind the material.
