Establishing San Diego as the venue for SPIE annual meetings was an activity loaded with unusual efforts and imagination on the part Joe Yaver, his wife, Anita, and some southern California members. Of interest is the origin (and retention) of SPIE as a name for the organization. Few know the associated logo has real technical meaning. Then there was moving SPIE headquarters to Bellingham, Washington, to complicate things.
We seek methods of stimulating young school children to develop an interest in science and engineering through a
natural curiosity for the reaction of light. Science learning now begins fully at middle school. Reading skills develop
with activity at home and progress through the elementary school curriculum, and in a like manner, a curious interest in
science also should begin at that stage of life. Within the ranks of educators, knowledge of optical science needs to be
presented to elementary school students in an entertaining manner. One such program used by the authors is Doug
Goodman's Optics Demonstrations With the Overhead Projector, co-published by and available from OSA (Optical
Society of America) and SPIE-The International Society of Optical Engineering. These demonstrations have been
presented in middle and high schools; however, as a special approach, the authors have developed selected Goodman
demonstrations as a "Magic Show of Light" for elementary schools. Teachers in the U.S. are overloaded with classroom
instruction specifically targeted at improving reading and math scores on the Standard Achievement Test (SAT);
therefore, science is getting "short changed" in the education system. For the sake of our future, industry volunteers
must come forward to promote interest in science beginning with K-6.

These demonstrations have found their way into middle and high schools; however, as a special approach, the authors have presented selected Goodman demonstrations as a "Magic Show of Light" to elementary schools. Both students and faculty have found the show most entertaining! If optical knowledge is utilized to stimulate science learning in the coming generation at elementary school level, there's a good chance we can sow some fertile seeds of advancement for all future segments of the workforce. Students can enjoy what they are doing while building a foundation for contributing gainfully to society in any profession. We need to explore expanding exposure of the “Magic Show of Light” to elementary schools.
We are witness to vehicle lamp technology experiencing significant development in the realm of halogen and high intensity discharge (HID) sources. As this is being written the ubiquitous light emitting diode (LED) is rapidly approaching headlamp reality. Government regulatory requirements challenge design, manufacture, and installation of headlamps. At the design stage lamp configurations use reflector and projector concepts. While reflector headlamps dominate the field, HID source small arc size often takes advantage of projector design by accomplishing both high and low beam settings using optical stops. These stops not only are a simple method of creating sharply defined beam tops, but also define beam top edges which aid significantly in aim adjustment. Evaluating quality of vertical beam alignment at vehicle assembly is often difficult to accomplish visually. While government regulations and automotive industry generic standards strive to define beam tops for ease of visual aim evaluation (audit), optical sensing offers improved audit repeatability and reliability. Therefore, new vehicle warranty claims related to headlamp beam vertical alignment can be minimized or even brought under complete control by proper vertical aiming and audit. An added result of well-managed headlamp beam alignment and audit at vehicle assembly is improved safety during night driving.
