PSP-CCD Features and Specifications
Description
The PSP-CCD is a 2-megapixel CCD camera designed to operate within a PSP system.
The camera is small and lightweight at 210g allowing for an array of cameras to be mounted in a
tight place for larger scale models and applications. The camera comes in two styles, one with a
color chip and one with a monochrome chip. The color camera is used in Binary PSP and
particle shadow velocimetry applications whereas the monochrome version is used in
monochrome PSP or S3F applications. One approach that allows binary pressure sensitive paint
data to be acquired using a single camera involves the use of a color camera (PSP-CCD-C).
Rather than use optical filters in front of the camera lens, the filtering is applied on the chip using
a standard Bayer filter. In the case of Binary FIB, the signal channel is acquired on the red pixels
and the reference channel is acquired on the green pixels. All images are acquired through a
single camera and lens and this process minimizes image alignment errors. This single chip
system also accomplishes a second goal, all data is acquired simultaneously, and thus the
stability of the illumination source is a less significant issue. The major drawback of this
approach is the loss of spatial resolution. In a color chip, only ¼ of the pixels are sensitive to the
signal channel (red pixels) on the standard Bayer filter. Despite the loss of spatial resolution, the
color camera approach produces excellent results at low speeds. The normal frame rate is 35 fps
but can operate at 44 fps in overclock mode. The camera features a software trigger and external
TTL trigger over BNC.
