Range-gated Camera
Product outline
Range-gated cameras are a type of laser cameras that use pulsed lasers as illumination light, and are characterized by
being less affected by rain and fog than laser cameras with a system of serial irradiation.
Range-gated cameras use a pulse for the laser light that they emit (laser light that is periodically and instantaneously turned on and off), and while this pulsed light reaches the subject, the shutters on the camera sides are closed. This method repeats the operation of opening the shutters only at the moment when the pulsed light returns to the camera sides. This makes it possible to obtain images of only the subject without receiving diffuse reflections from other sources such as moisture and dust.
Working principle
In images captured by laser cameras with a serial irradiation or by a searchlight illumination, the irradiation light is diffusely reflected by the moisture and dust in the air, such as the space up to the subject. This creates a white haze in the image and hides the subject.Range-gated cameras use a pulse for the laser light that they emit (laser light that is periodically and instantaneously turned on and off), and while this pulsed light reaches the subject, the shutters on the camera sides are closed.
