Measurement of angular velocity of a diffuse surface using speckel photography
ABSTRACT
We propose a method for measuring the angular velocity of a rotating diffuser by speckle photography employing a simple optical system and single exposure. The information is extracted by pointwise and Fourier filtering techniques.

A speckle pattern occurs when a ground glass for transmission and aluminum for reflection as...

Temperature measurement by using Mach-Zehnder interferometer
ABSTRACT
We proposed a method for measuring the temperature by using Mach - Zehnder Interferometer, one arms of Mach - Zehnder Interferometer was used as a test arms which was disturbed by an object, it's temperature was to be measured. In our experiment, we used a combustion flame and a heated...

Information multiplexing with theta modulation technique
Multiplexing is meant to record a number of different information in a piece of film. The multiplexing is conducted by giving a code to each information prior to the recording. In this research the multiplexing is done with the theta modulation technique, i.e. using a rotated grating so that each...

Properties of fourier intensity filter for optical diferentiation
Optical differentiation is one of many methods in the optical data processing that is useful for, e.g. image contouring. In this thesis, the differentiation filter is caried out based on the spatial filtering techniques. The ob ject is transformed with a Fourier lens to obtain the spatial frequency spectrum of...

Light scattering technique for measuring air pollutant particle concentration
In this research a scattering technique employing f or war dscatter of a He-Ne C0,5328 pm, 30 mw) laser beam together with a 1024 x 1024 arrays CCD-V11 video camera as a detector was used for determining both particle size distribution and concentration. For determining the size distribution the "Differential...
