Eye hazard and glint evaluation for the 5-MW/sub t/ Solar Thermal Test Facility

Abstract: UC-62 Potential eye hazards associated with concentrated reflected light are evaluated for the ERDA 5-MW t Solar Thermal Test Facility to be constructed at Sandia Laboratories. Albuquerque. New Mexico. Light intensities and hazardous ranges of single and multiple coincident heliostat beams are evaluated at ground level and in the air space above the facility. Possible long-range and short-range effects of distractive effects of reflected beams are discussed. Also described are certain beam control modification… Show more

“…Following methodology used in previous works [4] [9], two key parameters have been used to characterize the phenomenon of glare and assess the ocular impact: the retinal irradiance and the subtended angle (size) of the source. The relation between these parameters enables to define the situations where permanent eye damage or temporary blinding can occur.…”

“…The relation between these parameters enables to define the situations where permanent eye damage or temporary blinding can occur. Brumleve [4], based on results from previous works [10], proposed the expressions for the lower threshold from which permanent eye damage could occur:…”

“…The effects of glare on humans has been quantified by Metcalf and Horn [2], Saur and Dobrash [3], Severin et al [4], and Sliney and Freasier [5]. In other studies Brumleve [6], Chiabrando et al [7], and Ho et al [1] developed mathematical methods to quantify the potential danger of glare causing flash blindness. Flash blindness is defined by Ho as a "temporary disability or distraction" that can cause an afterimage and is understood to be comparable to what a human experiences when viewing the flash of a camera.…”

“…The potential eye hazard zone is generally confined to 20 to 30 m on either side of the focal point; the shorter focal length beams are the most hazardous (Brumleve 1977).…”
