摘要： An optical system calibration system and method particularly suited for calibrating the optical slit planes in an ophthalmic diagnostic instrument. The system includes an illumination source projector, an illumination image receiver, and a calibration component all having known relative positions, orientations and physical and optical characteristics. The calibration component includes at least two separated, diffusely reflecting surfaces. Images of an exemplary slit illumination pattern projected onto the calibration component and formed on the diffusely reflecting surfaces are detected by the image receiver such as a video camera. Based upon camera image coordinates and triangulation parameters of the projector, the receiver, and the calibration component, the slit image positions on the image detector plane can be calibrated to the axially displaced, diffusely reflecting calibration component surface positions.

摘要： The present invention contemplates an integrated oscillator-amplifier system for deep UV generation. The system employs a long cavity oscillator to lengthen the pulse build-up time and to control the pulse spectral bandwidth. Meanwhile the system employs a short cavity amplifier to shorten the energy extraction time to produce a single short pulse with good energy extraction efficiency. The system further integrates the oscillator and the amplifier by inserting the amplifier cavity inside the oscillator cavity via a mirror of low reflectivity. As a result, the integrated system has a long build-up time to generate a seed pulse in the long cavity oscillator and has a short energy extraction time to generate a short amplified single pulse in the short cavity. Consequently, the integrated system can accommodate a relatively long pump pulse to produce a single short amplified pulse suitable for deep UV laser generation.
