What Are the Components of a Handheld Thermal Camera

 

 

Objective Lens
The design of an objective lens and its parameters significantly influence the performance of a thermal camera device. The focal length of the objective lens directly influences the magnification of the unit (the bigger focal length, the bigger magnification), the field of view (decreases when focal length increases) and detection range.
One can say that the detection range directly depends on the focal length of the objective lens – the bigger focal length, the longer detection range (if the thermal sensor remains the same). The increase of focal length leads to an increase of magnification and a decrease in the field of view.
That is why when designing optical device it is necessary to take into account the tasks that the device has to perform – detect the object at long ranges and identify it due to its high magnification or find object fast due to its wide field of view
The most widely spread, but not the only, material used for manufacturing objective lenses of therma camera devices is single-crystal germanium, chalcogenide glass is also commonly used. To a certain extent sapphire, zinc selenide, silicon and polyethene also possess transmissivity in the MWIR and LWIR ranges.

 

Thermal Sensor (Microbolometer)
The photosensitive element of a thermal camera unit is a two-dimensional array of photodetectors – the focal plane array (FPA) and is based on various semiconductor materials. There are numerous technologies for manufacturing infrared-sensitive elements, however in the civilian field bolometers (microbolometers) prevail.
The microbolometer is a detector of infrared radiation that registers the change of electrical conductivity of a sensitive element when heated during radiation absorption.
Microbolometers are subdivided into classes depending on what sensitive material is used, this could be vanadium oxide (VOx) or amorphous silicon (α-Si).
The sensitive material absorbs infrared radiation and as a result, according to the law of energy conservation, the sensitive area of a pixel (single photosensitive element) is heated. The internal electric conductivity of an element alters and these changes are registered. The result is a monochrome or colour visualization of temperature image on the display of the unit. It is worth mentioning, that colour palettes on the screen fully depend on the software element of a thermal camera device.

 

Electronic Processing Unit
The electronic processing unit usually consists of one or several printed circuit boards (depending on the design of the unit), with specialized microcircuits responsible for processing the signal from the sensor and passing it further to display where an image of temperature distribution is formed. The boards also contain main control elements of device and power distribution circuits.

 

Microdisplay & Eyepiece
Since the majority of hunting thermal imagers use microdisplays, it is necessary to use an eyepiece for image viewing which operates as a magnifying glass and allows to view the magnified image comfortably.
Most commonly used are liquid crystal displays of a transmissive type (where the display is lit up from the reverse side) or OLED displays (when an electric current is applied its substance starts emitting light).
The use of OLED displays has several advantages: the ability to use the device in low temperatures, higher image brightness and image contrast, more simple and reliable design (no backlight source as in LCD). Apart from LCD and OLED displays, LCOS (Liquid Crystal on Silicone) displays can also be used, which are a variety of reflective type LCDs.

 

 

How Handheld Thermal Camera Work

Thermal cameras may seem complicated, but they are actually quite simple in their basic design. A thermal camera consists of five main components: an optic system, a detector, an amplifier, a signal processing unit, and a display.


The optic system is responsible for focusing the infrared radiation onto the detector, which is made up of an array of pixels that can detect the radiation and convert it into an electrical signal. The amplifier increases the electrical signal from the detector, and the signal processing unit converts the amplified signal into an image that can be displayed on the camera's screen.


Capturing thermal images involves using infrared radiation, which is emitted by all objects with a temperature above absolute zero. This radiation is invisible to the human eye, but a thermal camera can detect it and create a visual representation of the temperature differences in the scene.


The camera can capture thermal images by detecting the infrared radiation and converting it into a visual image. This process involves assigning colors to different temperature ranges, with cooler temperatures appearing blue or green, and warmer temperatures appearing red, orange, or yellow.

Handheld Thermal Camera Maintenance Methods and Precautions
 

Maintenance method

To avoid damage to the thermal camera, first use compressed air to remove large particles of dust attached to the inside and outside of the thermal camera, and then wipe it off with a clean, soft cloth. When cleaning the camera lens, gently wipe the lens with a soft cotton cloth dampened with a little non-corrosive solution or a mild diluted soap solution. When cleaning the thermal camera body, use a clean, slightly damp cotton cloth to gently wipe, if necessary, soak the cloth with a solution of water and a small amount of mild soap before wiping. When the use is completed, the thermal camera should be covered with the lens cover as soon as possible, and stored in the carrying case to avoid dust. After the thermal camera has been used for a certain number of years, it needs to be calibrated. Generally, it needs to be calibrated in about 2 years under normal use.

Maintenance precautions

First, do not use too much force when wiping the thermal camera to avoid damage to the thermal camera.
Second, when wiping the lens of the thermal camera, it is forbidden to completely immerse the cotton cloth in the liquid. The lens is the information transmission window, and the maintenance of the lens is very important.
Third, when wiping the camera body, be careful not to use strong acid or strong alkaline detergent for cleaning. Also, remember not to place the thermal camera in a cool and humid place.
Fourth, to avoid damage to the thermal camera, it is necessary to ensure that the working environment does not exceed the working tolerance limit of the thermal camera equipment.

Q: What can a thermal camera detect?

A: Thermal imaging cameras detect the surface temperature of the first object in their line of sight. By pointing it at a wall or other solid surface, it will measure the heat radiated outward.

Q: Can a thermal camera see through walls?

A: No, thermal cameras cannot “see” through walls or concrete. However, if there is a hot or cold pipe within the wall, it's likely a thermal camera will pick up on this. Thermal cameras do not see through solid objects. Instead, they detect the subtle heat signatures that transmit from internal elements through barriers.

Q: Can a thermal camera see hot air?

A: The air that surrounds us is one of the few materials that are transmissive to infrared radiation. Because of this, we cannot measure the temperature of the air with an IR camera. We must pay attention to the telltale thermal patterns that show us the effects of the air to find air leakage pathways.

Q: How to detect leak with thermal camera?

A: If there is water or extra moisture, you may see temperature fluctuations. On the camera's display, these temperature differences will show up as cool areas. Any possible signs of a water leak should be noted and looked into further.

Q: How do you read a thermal camera?

A: Thermal imaging cameras use color to show the relative temperature of objects: cold is purple, moderate is red, and hot is yellow. In the winter, purple spots inside your home indicate a lack of air sealing or insulation. In the summer, these spots would appear yellow instead.

Q: How far away can a thermal camera see?

A: Depending on the camera configuration chosen it may be possible to detect humans beyond 15 km distance, ground vehicles or small boats beyond 20 km, larger ships or vessels and aircraft beyond 30 km.
