A method for providing optical alignment for a visible wavelength reflective system is provided. The method includes positioning a first mirror blank on a lathe fixture. The first mirror blank comprises a single precision pinhole. The first mirror blank is secured to the lathe fixture. A first mirror is generated from the first mirror blank.

Method and system for providing optical alignment for a visible wavelength reflective system

A system and method for optical alignment of a color imaging system includes illuminating a target plate with a laser beam. Photo-luminescent energy from the target plate is emitted in response to the laser beam. A color imaging system is aligned based on the photo-luminescent energy emitted at the target plate.

System and method for optical alignment of a color imaging system

A sensor assembly (,) includes first and second focusing mirrors (,) which direct converging radiation to a tilted beam splitter (,) through an opening (,) provided in the first mirror. The beam splitter passes selected infrared radiation, which then passes through a lens system (,) to an infrared detector (,). The beam splitter reflects other radiation, which then passes through a different lens system (,) to a second beam splitter (,). The second beam splitter passes laser light, which travels through a lens (,) to a laser light detector (,). The second beam splitter reflects near-infrared radiation, so that it travels to a further detector (,).

Compact electro-optical sensor assembly having single aperture for multiple detectors

A FLIR system having a refractive FLIR optical configuration including a substantially spherical housing and an optical window disposed in and extending to the outer housing surface. The window aperture diameter exceeds the housing radius and is a near dome-shaped, relatively high dispersive negative lens forming a part of the FLIR optical system and is disposed adjacent a positive relatively low dispersive lens. A first optical system extends to a first housing window for receiving light and is within a hemispherical housing portion comprises an afocal lens system of a first pair of lenses, one lens disposed at a housing wall, a first mirror disposed within the hemisphere and reflecting light passing through the first pair of lenses, a second mirror for receiving the light reflected from the first mirror and reflecting the light along a path parallel to the light impinging upon the first mirror and a further plurality of lenses for transmission of the light reflected from the second mirror. The light reflected from the first mirror preferably is reflected in a direction normal to the light impinging upon the first mirror. A second window is disposed at the housing surface and a second optical system disposed within the housing is bounded by the hemisphere, receives light through the second window and is capable of selectively substituting the second optical system for a portion of the first optical system. Apparatus is provided to selectively substitute the second optical system for the first pair of lenses, the first mirror and the second mirror.
