Observations of glistening in the environment and its relationship to stereovision.

The relationship between glistening and stereovision is explored. Glistening is defined as the existence of points of light in the field of view of the observer that are observed substantially in only one eye. We define each glistening point to be essentially a point of stereonoise. A theory of the probability of glistening is developed and shows that a threshold point for 100% glistening should exist. The results of field experiments are presented.

Burst-Mode Frequency-Doubled YAG:Nd(3+) Laser for Time-Sequenced High-Speed Photography and Holography.

A frequency-doubled YAG:Nd(3+) laser system has been developed to serve as a source of illumination for high-speed photographic and holographic applications. A complete description of the laser system is presented. This laser is capable of generating a burst of 0.532-microm pulses of intense Q-switched light, equally spaced in time. Results presented include an example of a time-sequenced photograph of a hypervelocity impact and the reconstruction of an in-line hologram taken using the burst laser as a source. A summary of resolution and sensitivity of a series of photographic films for use at 0.6943 ,microm and 0.532 microm is also presented. This may prove useful in comparing ruby and doubled YAG:Nd(3+) for future photographic applications.
