3.1. Introduction to the sharpVISION™ Camera
The sharpVISION
™ digital cameras are high-resolution, high-performance cameras to be
used in industrial and scientific applications that include machine vision, microscopy and
Particle Image Velocimetry (PIV). The sharpVISION
™ cameras are built around the scientific
grade SONY ICX sensors. The ICX are progressive scan, CCD interline solid-state sensors
with a square pixel array. Progressive scan allows all pixel signals to be output in about 1/12
sec. This chip features an electronic shutter with variable charge-storage time, which makes it
possible to realize full frame still-image without a mechanical shutter. High sensitivity and low
dark current are achieved through the adoption of HAD (Hole Accumulation Diode) sensors,
while low noise electronics provide highly linear and stable digital data at fast frame rates (12
frames/sec).
The sharpVISION camera is available in two models:
• Non-cooled sharpVISION™ 1500-EX (Sony ICX285AL CCD).
• Cooled sharpVISION™ 1500-EX (Sony ICX285AL CCD).
The main features are:
• Binning 1x1, 2x2, 3x3 and 4x4.
• Framing rate 12-40 frames/sec.
• Up to 100 frames per second in ROI.
• External trigger capability.
• Synchronization
signal.
