A Heterodyning Range Imager
We describe a full-field range imager based on a heterodyning configuration. The scene is illuminated with a modulated light source. The received refl ected light is mixed in a high-speed shutter with a frequency shifted version of the light source modulation. This results in a low frequency signal, with the range encoded as phase, that is easily measured with standard CCD machine vision camera...
متن کاملHigh dynamic range, arbitrated address event representation digital imager
An 80 x 60 pixels arbitrated address-event imager has been designed and fabricated in a 0.6 μm CMOS process. The value of the intensity is inversely proportional to the inter-spike interval and the read-out of each spike is initiated by the pixel. The available output bandwidth is allocated according to the pixel's demand, favoring brighter pixels and minimizing power consumption. The imager ha...
متن کاملDefocus techniques for camera dynamic range expansion
Defocus imaging techniques, involving the capture and reconstruction of purposely out-of-focus images, have recently become feasible due to advances in deconvolution methods. This paper evaluates the feasibility of defocus imaging as a means of increasing the effective dynamic range of conventional image sensors. Blurring operations spread the energy of each pixel over the surrounding neighborh...
متن کاملExtending the Radar Dynamic Range using Adaptive Pulse Compression
The matched filter in the radar receiver is only adapted to the transmitted signal version and its output will be wasted due to non-matching with the received signal from the environment. The sidelobes amplitude of the matched filter output in pulse compression radars are dependent on the transmitted coded waveforms that extended as much as the length of the code on both sides of the target loc...
متن کاملHigh Dynamic Range Imaging and Low Dynamic Range Expansion for Generating HDR Content
In the last few years, researchers in the field of High Dynamic Range (HDR) Imaging have focused on providing tools for expanding Low Dynamic Range (LDR) content for the generation of HDR images due to the growing popularity of HDR in applications, such as photography and rendering via Image-Based Lighting, and the imminent arrival of HDR displays to the consumer market. LDR content expansion i...
