Abstract: PURPOSE: A method for measuring the performance of an optical system is provided to measure the performance of the optical system by rotating or moving a subject, a light collecting lens, and a mirror with a separate driving member, thereby easily measuring the performance of the optical system per field even in case of the optical system of large-diameter. CONSTITUTION: A method for measuring the performance of an optical system comprises a light source, a light collecting lens(220), a beam splitter(300), a mirror(400), and image senor. The light collecting lens collects lights penetrated through a subject by being irradiated to the subject. The beam splitter receives lights collected by the light collecting lens and irradiates the lights to the light receiving unit, and penetrates the lights through the optical system. The mirror is arranged in a side opposite to the light receiving unit and reflects the lights penetrated through the optical system and penetrates the reflected light through the optical system again. The image sensor is arranged in the light receiving unit side and receives the lights re-penetrated through the optical system, thereby imaging the subject.

Abstract: PURPOSE: An alignment device for optical image sensors is provided to determine a position of an image sensor by an alignment panel and a mirror without a high-priced collimator, thereby saving cost and minimizing the interference of external factors to an image formed in the image sensor. CONSTITUTION: An alignment device for optical image sensors comprises an optical lens(100), an alignment panel(200), a mirror(300), and an optical fiber module(400). The alignment panel is arranged on a focal plane of the optical lens. The mirror is arranged to face the alignment panel across the optical lens. The optical fiber module is installed at an arbitrary position of the alignment panel in a detachable manner. The optical fiber module sends light to pass through the optical lens, and receives the light which have been reflected by the mirror and passed through the lens back again.

Abstract: A method for calculating calibration errors by detector dark currents and a method for minimizing calibration errors using the same are provided to minimize the calibration errors caused by model errors, thereby selecting input luminance and exposure time necessary for linear gains and non-linear gains. Systematic errors caused by detector dark currents are calculated by using a radiation model error of an electron-optics camera. A radiation luminance estimation error caused by the radiation model error is calculated by a function 1. In the function 1, DN is an output digital signal of the electron-optics camera. T is exposure time. L is input radiation luminance of the electron-optics camera. An a is a linear gain of the electron-optics camera. A b is a non-linear gain of the electron-optics camera. O is an offset signal caused by the dark currents. F is a fixed offset signal. Alpha is a coupling signal between the input radiation luminance and the dark current offset. Beta is a non-linear dark current offset coefficient.
