Inside the thesis we can find information like incident angle, reﬂection, calibration, reﬂectance, light, direction, degrees, reflectance measurement, value, function, sensor, reﬂectance distribution function, and image synthesis. Lots of info about surface, speed, incident light, control, quantum efﬁciency, method, acquisition, light reﬂectance, power, system, irradiance, and shutter are presented in the thesis.
The thesis tells the reader information such as light source, ﬂux density, exposure time, data, wavelength, gonioreﬂectometer, device, distribution function, data acquisition, radiance, measurement system, and motion. Here are some excerpt from this thesis:
In this thesis, an automated measurement method is presented and implemented. A 3channel CCD camera is calibrated and used as the light measuring device. The system used is called ACME (ACtive Measurement Facilities). Within ACME, all devices in the system are under robotics control. Experiments are written in Java, and can be loaded from any machine via Internet and run on the local server. Several material samples are measured by using this system including paper and silk, and reliable data were obtained. The overall error is estimated to be less than 8%. It can be concluded that a CCD camera can be used to measure light reﬂectance properties for computer graphics, and it is relatively fast and convenient.
In addition, this thesis presents more such as angle, silver hemisphere reﬂectometer, incident, isotropic, bidirectional reﬂectance, reflectance, radiometer, plane, source, freedom, light measurement, and measurement.
