摘要： Three-Dimensional Defocusing Particle Image Velocimetry (3DDPIV) allows for measurement of three-dimensional velocities within a volume. In the disclosed embodiment, a mask with a plurality of apertures is disposed with a lens between the test section and a color camera. The field-of-view is backlit and the test section is seeded with black particles. This configuration allows for a lower power light source as compared to conventional 3DDPIV. Color-coded particle images are formed on a white background, wherein each of the color images is generated from light that travels through the filters not blocked by the imaged particle, thereby producing a color image that is of a color different from the color of any of the filters. A color space linear transformation is used to allow for accurate identification of each pinhole exposure when the color filters' spectrum does not match those of the 3-CCD color camera.
