Describes a method in which the effect of impurity ions in the dielectric is taken into account in the operation of the Kerr cell. (Author/CP)

Presents a simple method of analysis in which the student can integrate, point by point, any interferogram to obtain its Fourier transform. The manual technique requires no special equipment and is based on relationships that most undergraduate physics students can derive from the Fourier integral equations. (Author/MLH)

This is a textbook of Fourier optics for the classroom or self-study. Major topics included in the 38 chapters are: Huygens' principle and Fourier transforms; image formation; optical coherence theory; coherent imaging; image analysis; coherent noise; interferometry; holography; communication theory techniques; analog optical computing; phase…

Provides directions for construction of a working model of the eye and specifies some experiments using this model. (PEB)

Presents a summary of the state of the field in instrumentation as it existed in 1940-1941 as described in articles written at that time by R. H. Muller. (SLH)

In this simple experiment for an undergraduate laboratory a laser beam is passed through the mixing zone of two liquids with different refractive indices. The spatial variation of the refractive index, at different times during the mixing, can be determined from the observed deflection of the beam. (Author)

The purpose of the Laser/Electro-Optics Technology (LEOT) Project was to establish a pilot educational program, develop a flexible curriculum, prepare and test instructional materials, transport the curriculum and instructional materials into other educational institutions by establishing relevant LEOT programs wherever they are needed, and to…

Optical and electromagnetic fundamentals are presented in this fourth unit of the Project Physics text for use by senior high students. Development of the wave theory in the first half of the 19th Century is described to deal with optical problems at the early stage. Following explanations of electric charges and forces, field concepts are…

The construction and validation of a test to assess the concepts of light and shadows contained in the New York City Board of Education bulletin "Science K-2" are described. The final form of the Non-Reading Concept Test is a filmstrip with 32 color drawings. The first two items are trial questions to familiarize students with the test format. The…

As a result of work performed at the Southwestern Radiological Health Laboratory with respect to lasers, this manual was prepared in response to the increasing use of lasers in high schools and colleges. It is directed primarily toward the high school instructor who may use the text for a short course in laser fundamentals. The definition of the…

Describes the operation and numerous educational uses of an electronic music synthesizer. Capabilities (and limitations) of the synthesizer for use as a wave demonstrator are presented. (CP)
