Differences between infrared cameras and camcorders and laser cameras

Infrared cameras/camcorders and laser cameras are two different types of cameras/camcorders and there are some distinct differences between them.

Firstly, infrared cameras/cameras use infrared light to capture images. Infrared is a part of the electromagnetic spectrum with wavelengths ranging from 700 nanometres to 1 millimetre. Because objects absorb and reflect infrared light to varying degrees, infrared cameras/camcorders are able to capture objects or phenomena that are not visible to the human eye. For example, at night or under low-light conditions, infrared cameras/camcorders can clearly capture the outline or movement of a target object, whereas ordinary cameras/camcorders are unable to capture such details. In addition, infrared cameras/cameras can capture colours or moving objects that are difficult to see with the naked eye in certain special environments.

In contrast, a laser camera is a camera/camcorder that uses a laser light source as an illumination device. A laser is a high-energy light beam that is highly concentrated and monochromatic. Laser cameras typically use semiconductor lasers or solid-state lasers, which are capable of emitting a high-energy laser beam to provide clearer and more precise images. The light source of a laser camera can be adapted to different application scenarios by adjusting the wavelength and power. For example, at night or under low-light conditions, the laser camera can provide brighter and clearer images, while also suppressing background noise and improving image quality.

In addition, laser cameras can be used for some special measurement and control applications. For example, laser cameras can be used to measure parameters such as distance, speed, and angle of a target; they can also be used for navigation and control in areas such as robot vision, automated production lines, and driverless vehicles. These applications are not possible with ordinary infrared cameras/cameras.

In addition, infrared cameras/cameras and laser cameras have some differences in design and application. For example, infrared cameras/cameras usually use special infrared filters and sensors to capture infrared signals, whereas laser cameras need to take into account factors such as the stability of the laser light source, the quality of the light beam, and the angle at which the light beam is projected. In addition, laser cameras are more expensive and costly to maintain, requiring specialised technicians for commissioning and maintenance; whereas infrared cameras/cameras are relatively less expensive and less costly to maintain.

In summary, infrared cameras/cameras and laser cameras differ somewhat in design and application. Although they can both be used for image capture and visualisation applications, they differ in their scope of use, performance and application scenarios. Therefore, when choosing to use a camera/camera, you need to select the right type of camera/camera based on actual needs and application scenarios.
