A novel method for imaging velocimetry of range motion distribution is proposed. It is based on what we call "moire Doppler effect" and temporal frequency estimation on each pixel. We project a grating pattern translating with a constant speed. Every point on the object illuminated by it returns a sinusoidally varying intensity, and is detected by the Correlation Image Sensor (CIS). In this...
We deal with the problem of direction and distance estimate of emission sources in 3-D space. We first introduce a partial differential equation (PDE) what we call the location constraint PDE (LC-PDE), which provides a necessary and sufficient description of wavefield generated by a source at direction n and distance R. To remove differentials, we integrate the LC-PDE in a finite rectangular area...
