Describes an experiment in which a simple laser-based apparatus is used for measuring the change in refractive index during the acid-catalyzed hydrolysis of glycidol into glycerine. Gives a schematic of the experimental setup and discusses the kinetic analysis. (MVL)

Outlines what a hologram is, the main types of holography, and how a simple system producing a white light reflection hologram can be set up in a school physics laboratory. Discusses the basic optics of the hologram and procedures and materials for making holograms in school. (YP)

Describes a method to create holograms for use in different interferometry techniques. Students utilize these techniques in experiments to study the structural integrity of a clarinet reed and the effects of temperature on objects. (MDH)

Describes a homemade experimental chamber constructed to accurately measure the refractive index of a transparent liquid. (MDH)

Describes features of laserdisc and discusses its advantages over videotape and audiotape in the areas of image and sound quality, random access, and permanence. Current and future applications of laserdisc technology in art and music are highlighted. (MAB)

This article describes how to construct a laser level. This laser level can be made using a typical 4' (or shorter) bubble level and a small laser point. The laser unit is detachable, so the bubble level can also be used in the conventional way. However, the laser level works better than a simple bubble level. Making this inexpensive device is an…

The potential of holograms has been left virtually untapped in the field of education. A hologram can be described as a three-dimensional photographic record of the interference pattern of two superimposed beams of coherent light. Holography requires: (1) high-resolution film; (2) a laser, often a red-beamed helium neon laser; (3) optical…

Presented are reports on trends and probable future developments in eight selected areas of basic science and engineering. These reports are: "The Genetic Program of Complex Organisms" (Maxine F. Singer); "The Molecular and Genetic Technology of Plants" (Joseph E. Varner); "Cell Receptors for Hormones and…

This final report contains the program proposal with supporting data for developing curriculum materials for and implementing an associate-degree laser technology program at the North Central Technical Institute. The proposal outline provides this information: (1) objectives for the program designed to prepare a technician to safely operate,…

Provides reading professionals with an overview of reading and literacy applications in optical technology, including videodiscs, compact discs, and other optical technology. (ARH)

Eight papers cover: optical storage technology; cross-cultural videodisc design; optical disk technology use at the Library of Congress Research Service and National Library of Medicine; Internal Revenue Service image storage and retrieval system; solving business problems with CD-ROM; a laser disk operating system; and an optical disk for…

Presents: (1) method for tuning sonometers with a VELA and sensing device; (2) computer simulation of two-dimensional gas diffusion; (3) inexpensive procedure for digitizing with better than 0.5mm precision (with program listing); and (4) a simple optical diffraction analogue apparatus for use with the laser. (DH)

Reviews attributes of laser discs and "traditional" objections to use of audiovisual materials. Use of authoring systems as means of tailoring laser disc programs and updating aging materials is described. Flexibility and power of the Video Nova Authoring System is explained and illustrated and the SONY SMC-70 microcomputer is evaluated.…

Describes a multidisciplinary project/experiment in which undergraduate students repaired a nonfunctional Helium-Neon laser. Includes experimental procedures used and results. (JN)

Describes a topics course offered at the University of New Mexico entitled "Lasers in Chemistry," which is designed for beginning graduate students and advanced undergraduates in all areas of chemistry. (CS)
