ABOUT THE OPTOLINER SYSTEMS
|Brief History and System Features|
The K-Series Optoliner System is an updated, modern version of the familiar product line geared to provide an efficient, reliable, and accurate tool to the TV camera test engineers.
The heart of the system is the test pattern projector available in five model versions each providing a different image format to best fit a given camera. Precision lenses project sharp distortion-free images of selected test pattern onto the TV sensor area with a high degree of uniformity of light.
A large variety of test patterns provides the test engineer with the capability to check parameters such as sensitivity, gamma, geometric distortion, resolution as a contrast function or light level registration. linearity, system square wave response, color registration, and many more.
A full line of Neutral Density Filters allows testing of cameras at extremely low light level.
The system is compact and can be operated in bright daylight. It eliminates the need for wall charts. Target patterns, filters, and various illumination systems can be removed and replaced in a matter of seconds. Each system is supplemented with a test data package containing results and computer plots.
The Digital Multi-Purpose Meter is capable of measuring color temperature, three decades of illuminance, and lamp voltage, all selectively displayed on a panel meter. The readings are continuously monitored while the Optoliner projector is coupled to the TV camera. This is made possible by placement of the probe head inside the OC projector. A single cable carrying lamp power and signels connects the projector to the meter.
The incandescent, detachable illumination system utilizes an integrating sphere with three light bulbs wired in series. It can be interchanged with alternate illumination systems, eg. Xenon flash illumination system. Lamp power and trigger signals for the ring shaped Xenon flash bulb are supplied from a separate driver through a high-voltage connector and cable.
Davidson Optronics is aware of the increasing variety of TV cameras and E-O sensors on the market, and is prepared to assist its customers in redesigning any of the standard models for special application. This may result in adding filters for specific spectral bands, in adapting to non-standard camera mounts, in choosing a projection lens magnification that would render image sizes different from the ones of the five standard models, or in providing a larger integrating sphere yielding an even better uniformity of illumination.
