A Nonscanning Confocal Camera for High-Speed Precise Surface Profiling

Abstract:

Physical Optics Corporation proposes to develop a novel nonscanning
confocal camera (NSCC) for high-speed precise 3-D surface
profiling. The proposed NSCC projects 4 x 104 confocal beam probes
onto the surface under test and simultaneously performs depth
measurements for all points by axial scanning only and preserves
the high depth resolution of conventional single beam probe
systems. With sophisticated system design and data processing, the
developed NSCC will be high-speed, highly accurate, very compact
and rugged. The NSCC can be integrated into a small robot for
nondestructive testing.

The NSCC can be used for defect detection, strain measurement,
precise surface profiling for propellers in aircraft, ships or
electrical generators. It can also be used for cornea or retinal
mapping.
