Question:

An electro-optic modulator is a device that switches a laser beam rapidly from off to on by switching the polarization direction through 90° when a voltage is applied. But a brownout results in only enough voltage for a 72° rotation. What fraction of the light is transmitted during the brownout when the beam is supposed to be fully on?

A hologram is a three-dimensional image created by the interference of light beams from a laser or other light source. The holographic image appears to be floating in space and can be viewed from different angles, just like a real object. Holograms have many practical applications, including security features on credit cards and passports, 3D displays for medical imaging and scientific visualization, and holographic art and entertainment. The process of making a hologram involves recording the interference pattern of laser light on photographic film or other recording media, and then reconstructing the pattern with a laser to create the holographic image. To begin making a hologram, start by drawing shapes and marking measurements on a large cardboard using a scale, cutter, and pencil or pen. Cut out the cardboard pieces according to the measurements, and spray each piece with a coloring spray for a better look. Create a mobile holder by attaching long and small cardboard bars to a rectangle-shaped cardboard base with glue. Make side walls by placing cardboard wall pieces on top of the base and securing them with glue. For the screen, use a polypropylene sheet and attach it to the side walls with needles and glue. Place small triangular-shaped side walls on top of the pp sheet and secure them with needles. Add a black cardboard paper back cover to the hologram by measuring, cutting, and gluing it to the back walls. Test the hologram by playing a hologram video on a mobile.
