摘要： PROBLEM TO BE SOLVED: To apply a silicon carbide optical system having ≥1 m aperture to a visible light region by using a particle-dispersed silicon material having silicon carbide as dispersed particles to eliminate a need of coating of a silicon carbide film which is formed by chemical vapor deposition and required when manufacturing a conventional optical system using sintered silicon carbide. SOLUTION: A mirror plane matrix employs, as a mirror member matrix, the particle-dispersed silicon material having silicon carbide as dispersed particles. A mirror plane having a reflecting film formed on a mirror member obtained by mirror polishing of the mirror member matrix is used to form an optical system having a large aperture.

摘要： PROBLEM TO BE SOLVED: To promote the simplification of a configuration and miniaturization and reduced weight and to achieve accurate spectral observation by providing a prism where a light incidence surface being inclined at a specific angle to a direction that orthogonally crosses the inclination direction of a diffraction grating is provided. SOLUTION: A spectroscope used for an infrared sensor or the like being mounted to an artificial satellite is provided with a prism 12, and its light incidence surface 121 is inclined at a specific angle δ for a direction that orthogonally crosses the direction of the wavelength dispersion of a light detection part 14. Then, when light to be detected is applied to a slit 10, is guided to a light incidence surface 121 and passes through a diffraction grating surface 122, the light to be detected is separated in a direction where primary and secondary beams with different wavelengths nearly orthogonally cross the direction of light dispersion and enter a light detection part 14, thus separating and extracting light with a different wavelength with an at least one octave wavelength region without further equipping an extraction part or the like at the later stage of the prism 12.

摘要： PURPOSE:To efficiently radiate laser beams for beacon with the optimum pattern characteristics by irradiating with laser beams for beacon the peripheral section of a main mirror with a prescribed extent through an auxiliary mirror, and sending out the laser beams for beacon in the direction of the optical axis of a laser beam for communication. CONSTITUTION:For a reflection type optical system for communication laser composed of a main mirror 21 and auxiliary mirror 22, laser beams for beacon irradiates the peripheral section of the main mirror 2 with a prescribed extent through the auxiliary mirror 22 so that reflected beams are not affected by the mirror 22 and the laser beams for beacon can be sent in the direction of the optical axis of a laser beam for communication. The laser beams for beacon are outputted from the main mirror 21 of the reflection type optical system by reflection by projecting the laser beams on the peripheral section of the mirror 21 in an out-of-focus state and at spread angle. Therefore, the area loss by the auxiliary mirror 22 can be prevented and efficient beam transmission can be realized and at the same time, the direction in which the beams are blocked and not radiated by the auxiliary mirror 22 is eliminated. Thus an appropriate beam pattern can be obtained.

摘要： PURPOSE:To determine the optical image center position with high accuracy by a simple constitution by comparing an integral value of a solar light photodetecting output by a linear array sensor and a reference level based on the previous integral value, measuring the time when the comparison output is inverted and determining a solar optical image position. CONSTITUTION:An output of a CCD linear array sensor 45 in which a photoelectric converting element is placed in the direction orthogonal to the forming direction of a slit for limiting a solar luminous flux in the prescribed direction is read out and integrated by an integrator 14, and this integral value and a reference value outputted from a voltage dividing path 16 based on the previous integral value are compared by a comparator 17. Subsequently, a latch circuit 19 is controlled by the comparator 17, and a time measured value by a scaler extending from a first integration start to an inversion of an output of the comparator 17 is outputted as an angle of a solar optical image center position. By this simple constitution which necessitates no complicated digital circuit, etc., the solar optical image center can be determined with high accuracy without an error by

摘要： PURPOSE:To improve the sensitivity of a sensor by using an area CCD as a photodetector and assigning the time delay integrating operation to it. CONSTITUTION:An artificial satellite spin axis is set in the horizontal CCD transfer direction 13 of the area CCD12 and the direction of the movement of a start image 17 on a focal plane by an artificial satellite spin omega, i.e. the area CCD12 is made coincident with the vertical CCD transfer direction 18 of the area CCD12. The area CCD12 is driven by a CCD driving circuit 15 differently from a system which is used for a normal television camera, etc., and a cycle of a field shift, one-stage transfer in the vertical CCD transfer direction, and a read of one horizontal line is repeated. This reading operation is synchronized with the motion of the star image by artificial satellite spin motion to extend an effective area CCD storage time, thereby improving the sensitivity of the sensor greatly.

摘要： PROBLEM TO BE SOLVED: To realize small size and light weight and further realize measurement of high reliability and precision. SOLUTION: A first coil part 12 and a second coil part 13 are arranged in a fixed part 10. A third coil part 17 is so arranged in a movable part 11 that the coil part 17 faces the coil parts 12, 13.

摘要： PURPOSE:To measure an inclination angle of the scanning mirror of a Michelson interferometer used in a space navigation body by detecting a light generated as a result of interference between a laser beam reflected on a fixed mirror and a laser beam reflected by the scanning mirror through a semi-transparent mirror. CONSTITUTION:A laser beam from a laser generator 15 is injected perpendicular to an optical axis for connecting an observed object 19 of a Michelson interferometer to a semi-transparent mirror 11 and is reflected in parallel with the optical axis by a reference mirror 16a. The reflected light is branched in two directions by the semi- transparent mirror 11 as light from the observed object 19, and the ones reflected by a fixed mirror 12a and a scanning mirror 12b interfere with each other. An interference laser beam is reflected by the reference mirror 16a and received by detectors 17a, 17b. The interference laser beam changes its intensity in accordance with the difference of a distance between the semi-transparent mirror 11 and the fixed mirror 12a and the distance between the semi-transparent mirror 11 and the scanning mirror 12b. As wavelength of the laser beams is already known, the difference in the distances is known from change of intensity of the interference laser beam. A signal processing device 18 finds an inclination angle from change of intensity of the reference laser beam observed by the detectors 17a, 17b.
