Abstract: An apparatus and a method for calibrating displacement change of a diffractive part in a diffractive optical modulator are provided to receive an optical strength measuring value inputted from an optical detection part, and to output an element calibration data through a calibration value calculating part for measuring the change of the displacement and calibrating the change of the measured displacement. An apparatus for calibrating displacement change of a diffractive part comprises a memory(614), a sampling data output part(616), an optical modulator driving circuit(618), an optical detection part, a control part, and a calibration value calculating part(628). The sampling data output part reads and outputs the calibration value calculation sample data stored in the memory. The optical modulator driving circuit drives the diffractive optical modulator according to the sample data outputted from the sampling data output part. The optical detection part measures and outputs the optical strength of the diffractive light. The control part controls the sampling data output part and controls the calibration value calculating sample data to be outputted. The calibration value calculating part receives the optical strength measuring value inputted from the optical detection part and outputs the element calibration data. Thereby, a pixel matching sample data is stored in the memory. The sampling data output part outputs the pixel matching sample data to the optical modulator driving circuit. The optical detection part is a photo diode array(630).

Abstract: A polygonal reflective illumination apparatus is provided to increase resistance against dusts and humidity by implementing an illumination apparatus in a polygonal reflective configuration. A polygonal reflective illumination apparatus includes a shielding case(100), an optical source(112), a first reflector(122), a fly-eye lens group(124), and a second reflector(132). The shielding case is fixed on a frame and includes an inner cavity and input and output holes. The optical source is attached to the input hole and irradiates light into the cavity. The first reflector is attached inside the cavity and reflects incident light from the optical source into parallel light. The fly-eye lens group is attached inside the shielding case, generates uniform parallel light from the light reflected by the first reflector, and outputs the uniform parallel light. The second reflector is attached inside the cavity and reflects the incident light, which is reflected by the fly-eye lens group, to the output hole.
