Volume phase holographic (VPH) optical elements have made a major contribution to Raman spectroscopy by providing notch filters, and VPH gratings that provide remarkable performance advantages over previous technologies. Holographic notch filters have eliminated Rayleigh scattered laser light from single monochromators, thereby contributing to the…

Describes some of the techniques that enable the amateur microscopist to make scientifically revealing photographs, using simple and inexpensive equipment. (GA)

Describes a college level minicourse utilizing photography and the camera to present basic physical optics. Included is an outline of topics and a listing of course objectives. (SL)

Describes a method for determining the exposure correction factors in close-up photography and macrophotography. The method eliminates all calculations during picture-taking, and allows the use of a light meter to obtain the proper f-stop/exposure time combinations. (Author/MLH)

Photographs illustrate several principles of physics which can be observed in everyday situations. (CP)

Details a method of taking short interval photography with inexpensive equipment. (CP)

Photographs and text describe techniques by which color negative film can be developed and printed. An equipment list, by which black and white printing facilities can be converted to make color prints, is provided. (CP)

Describes an inexpensive fog machine that is useful for photography and laser demonstrations. The apparatus uses liquid nitrogen to chill steam to make a fine mist safe for precision optics. The device can be made for around $50. (MVL)

Described is the phasor method of superposition of waves. The intensity pattern from a system of microwave sources is calculated point by point on a plane corresponding to a film emulsion, and then printed and directly converted to a hologram for 3-cm microwaves. Calculations, construction, and viewing of holograms are included. (Author/DS)

Investigates the "photographic" appearance of a cube moving at relativistic speeds, and shows that it depends upon whether the camera is held fixed with the optic axis perpendicular to the direction of motion or panned to follow the cube as it moves. (Author/GA)

Presented is information to supplement elementary physics texts so that teachers may expand the presentation of classical optics to include some basic concepts related to photographic systems. (SL)

Demonstrates how depth of field, exposure correction, and Scheimpflug focusing are obtained for a view camera, using elementary optics. (CS)

Describes a method for capturing a real object and its real image on film. Explains many photography terms related to the experiment. (MVL)

Presents an experiment to demonstrate the diurnal and seasonal motions of the sun, which can be used in different grade levels, depending on the degree of difficulty required for the analysis, as an effort to generate student interest in the scientific method. Includes an activity to teach students elementary concepts of the sun's apparent motion…

Describes how astrophysics can be a do-it-yourself project within a school boy's budget and background, by giving detailed instruction on equipment construction. In addition, this article describes many experiments to undertake, with the equipment, such as determining color temperature, star spectra, chemical composition and others. (BR)
