Over the past decade, smartphones have become an essential part of our daily lives, capable of performing various tasks that we previously thought were possible only with specialized equipment.
People have become more reliant on their smartphones for photography, and with each new model, manufacturers strive to improve the camera capabilities. However, one question that often arises is whether an iPhone camera can see thermal images.
Thermal imaging technology allows users to see and capture heat signatures emitted by objects or living beings. It is commonly used in various industries, including firefighting, search and rescue operations, and even medical diagnostics.
In general, iPhones do not have the built-in capability to see thermal images. Unlike specialized thermal cameras, which have sensors specifically designed to capture heat signatures, smartphones primarily rely on visible light to capture images and videos.
However, there are external thermal camera attachments available in the market that can be connected to an iPhone. These attachments utilize their own thermal sensors to capture heat signatures, allowing users to view and capture thermal images using their iPhone.
Understanding Thermal Imaging
A thermal imaging camera is a device that can detect and capture heat patterns and temperature variations in objects and environments. It works by utilizing infrared radiation emitted from objects, which is not visible to the human eye but can be detected and analyzed by thermal cameras.
Thermal imaging technology measures the amount of infrared radiation emitted by an object or surface. The camera then converts this radiation into a visual image, where different colors or gradients represent various temperature levels. Hotter objects appear in warmer colors like red, orange, or white, while cooler objects appear in cooler colors like blue, green, or black.
Thermal imaging cameras can be used in various applications. In industries such as electrical maintenance, they are used to detect overheating electrical components, identifying potential issues or malfunctions. In building inspections, thermal cameras can locate areas of heat loss, identify leaks, or detect hidden structural defects. They are also used in surveillance and security systems to spot intruders or track movements in complete darkness.

How Thermal Imaging Works
Thermal imaging is a technology that allows us to visualize and measure the thermal energy or heat emitted by objects and living organisms. It works by detecting and capturing the infrared radiation, which is invisible to the human eye but can be sensed by specialized thermal cameras.
Principles of Thermal Imaging
Thermal imaging relies on the principle that all objects emit infrared radiation as a result of their temperature. The hotter an object is, the more thermal energy it emits. A thermal camera captures this radiation, converts it into an electronic signal, and then creates an image based on the detected heat signatures.
Thermal Camera Technology
Thermal cameras consist of various components that enable them to detect and interpret infrared radiation. These components include:
| Sensor | The sensor is the most crucial component of a thermal camera. It consists of an array of tiny infrared detectors called microbolometers, which can sense the infrared radiation. |
| Optics | The optics of a thermal camera are designed to focus the infrared radiation onto the sensor. They typically consist of lenses made from special materials that can transmit infrared radiation effectively. |
| Signal Processor | The signal processor of a thermal camera converts the electronic signals from the sensor into a digital format that can be interpreted by the camera’s software. It also enhances the image quality and applies filters to improve the visibility of temperature differences. |
Once the thermal camera captures the infrared radiation and processes the signals, it creates a thermal image where different colors or intensity levels represent different temperatures. These images can be displayed on the camera’s screen or exported to a computer for further analysis.
Thermal imaging has various practical applications, including building inspections, electrical and mechanical inspections, wildlife observation, medical diagnostics, and even public safety and law enforcement. Its ability to detect and visualize temperature differences provides valuable insights in many fields.
