What is focal plane array detector?

Focal Plane Array (FPA), sometimes called staring array or staring-plane array, is an image sensing device. It is special type of bolometer thermal detector. Focal plane array consists of a series of small thin-film bolometers arranged in a matrix in the focal plane of the detector.

Is a CCD A focal plane array?

Applications of the Focal Plane Arrays Particularly widespread are silicon-based CCD and CMOS sensors, as used e.g. in photo cameras and video cameras; they have nearly completely replaced the formerly used vidicon tubes.

What is FPA imaging?

The principle of an FPA detector is analogous to that of a digital camera. Instead of visible light, however, a defined array of pixels is illuminated by infrared light, with each detector pixel recording an independent, spatially resolved IR spectrum.

What is uncooled focal plane array?

Uncooled infrared focal-plane array offers low-cost thermal imagers. Expanded military and commercial applications of thermal imaging are seen by Amber (Goleta, CA) as a result of its fabrication of an uncooled infrared (IR) focal-plane array based on microbolometer technology developed by Honeywell (Bloomington, MN).

What is Mwir?

Medium-wave infrared (MWIR) is a subdivision of the IR band of the electromagnetic spectrum, which captures infrared energy in the 3 to 5 micrometer medium-wave infrared (LWIR) spectrum.

What is the focal plane of a lens?

The focal plane is the distance between your camera lens and the perfect point of focus in an image. This area is located a certain distance in front of your camera lens, and spans horizontally, left to right across your frame.

What is a ROIC sensor?

A Readout integrated circuit (ROIC) is an integrated circuit (IC) specifically used for reading detectors of a particular type. They are compatible with different types of detectors such as infrared and ultraviolet.

How does FTIR microscope work?

The FTIR spectrometer enables the microscope to use infrared spectroscopy to make a chemical analysis of the sample. The infrared detector may detect infrared light at a single point, a linear array or a focal plane array to view different sections of the sample.

What is SWIR and MWIR?

The three wavelengths are: Short Wavelength Infrared (SWIR), Medium Wavelength Infrared (MWIR), and Long Wavelength Infrared (LWIR). All Thermal imaging devices operating on the infrared wavelength are, ‘imagers’ that we commonly refer to as ‘cameras’, however they are actually sensors that can detect radiated heat.

What is the difference between LWIR and MWIR?

Infrared Imaging White Paper As shown in Figure 1, photovoltaic infrared detectors (such as MCT and InSb) are currently available for imaging is several distinct bands, including SW/MWIR (1.5-5.0µm), MWIR (3- 5µm), LWIR (7.5-9.5µm) and VLWIR (7.5-11µm).

How does focal plane affect aperture?

The smaller the aperture, the greater the depth of field for whatever focal length is being used (ƒ/22 has much greater depth of field than ƒ/5.6, for example). The shorter the focal length, the greater the depth of field from near to far at any given aperture.

What is a focal plane array?

Typically, a focal plane array is a rectangular two-dimensional array containing many thousands or even a several million detectors.

Why digital pixel focal plane array (dfpa)?

While conventional technologies perform well in limited circumstances, scal – ing the technologies to meet these emerging demands is difficult and results in large, complex, expensive systems. The digital-pixel focal plane array (DFPA) was developed to address the shortfalls of conventional FPAs.

What is AFPA (adaptive focal plane array)?

Adaptive focal plane arrays (AFPA) are high-performance devices that are widely tunable across various wavebands in the infrared (IR) spectrum. They enable multi-spectral imaging across the short-wave infrared (SWIR), mid-wave infrared (MWIR), and long-wave infrared (LWIR) bands.

Is there an infrared detector with a focal plane?

However, there are also focal plane arrays containing infrared detectors for wavelengths of several micrometers.
