“…FOI conducted extensive theoretical and application research. Ove Steinvall et al's review article in 2007 [ 13 ] introduced the FOI achievements in GVT system research, including system design, concealed target imaging detection, imaging through fog and flames, moving target imaging, 3D imaging and target laser optics OPO [.l recognition [14] , system performance evaluation and other studies, and then innovatively put forward a method of using readability to measure laser image quality. Figure 4 shows the result of FOI range-gated 3D imaging, wherein (a), (b), and (c) were gated slice images of different parts of the car about 7.2km way.…”

“…Besides, range-gated imaging can capture high-quality gate images by suppressing backscattering. So active range-gated imaging has been widely used in night vision [1,2], 3D imaging [3,4], remote imaging [5], underwater imaging [6,7], 4D imaging [8], and security surveillance [9].…”

A control software named as gated imaging lab (GIL) for 2D/3D underwater or atmospheric range-gated imaging has been introduced. First, a detailed analysis of the functional requirements of imaging system is made. Based on its operating principle and hardware components, functional modules of GIL are determined. It mainly includes zooming and focusing lens, setting gated intensified charge-coupled device (ICCD), changing laser divergence angle, controlling synchronization timing control unit and reconstructing three dimensional (3D) scenes based on captured images. MFC framework simplifies the method of software design and improves the degree of reuse and development efficiency of GIL. Experiments demonstrate that GIL system is stable, real-time and can meet the application demands.

Active Range Imaging (ARI) has recently sparked an enthusiastic interest due to the numerous applications that can benefit from the high quality depth maps that ARI systems offer. One of the most successful ARI techniques employs Time-of-Flight (ToF) cameras which emit and subsequently record laser pulses in order to estimate the distance between the camera and objects in a scene. A limitation of this type of ARI is the requirement for a large number of frames that have to be captured in order to generate high resolution depth maps. In this work, we introduce Compressed Gated Range Sensing (CGRS), a novel approach for ToF-based ARI that utilizes the recently proposed framework of Compressed Sensing (CS) to dramatically reduce the number of necessary frames. The CGRS technique employs a random gating function along with state-of-the-art reconstruction in order to estimate the timing of a returning laser pulse and infer the depth map. To validate our method, software simulations were carried out using a realistic system model. Simulated results suggest that low error reconstruction of a depth map is possible using approximately 20% of the frames that traditional ToF cameras require, while 30% sampling rates can achieve very high fidelity reconstruction.
