摘要： PURPOSE:To eliminate the contour of a planar object and ensure the extraction of only the contour of a linear obstruction from the contours of the linear obstruction and the planar object extracted via a differential process. CONSTITUTION:The contours of a linear obstruction and a planar object are extracted from distance information from a laser radar 1 and angle information from a scanner 2 through a differential process section 31. Furthermore, a distance data difference available from, for example, seven or more distance data, when smaller than a certain value, are judged as representing the planar object, and subjected to an elimination process at a planar object eliminating process section 32. As a result, the data of only the linear obstruction is extracted.

摘要： PURPOSE: To prevent the deformation of the reflection mirror of a high power laser caused by the pressure of coolant. CONSTITUTION: When coolant R flows into a coolant groove 5, the pressure of the coolant R is directly applied to a back plane 1b of a metallic mirror 1. Since the rigidity of a cover material 15 is smaller than the rigidity of the mirror 1, the material 15 is deflected to a space 23 side by the pressure of the coolant R, the deformation of the mirror 1 is prevented and as a result, a high surface precision of the mirror 1 is maintained.

摘要： PURPOSE:To make a multi-dither system compensating optical device, which corrects optical wave front distortion of a light wave, high in performance, small in size, and fast. CONSTITUTION:A light signal 1 is converted by an A/D converter 2 into a digital signal 3, and plural digital signal processing parts 4a 4n detect plural phase-modulated signals that the light signal 1 contains and operate and output command voltages 5a-5n for their corresponding actuators to a driving power source 6. A driving voltage 7 is outputted from the driving power source 6 to the respective actuators of a shape changeable mirror. Thus, the digital signal processing parts 4 detect the phase-modulated signals, so performance deterioration of a secular change of a circuit element which is caused by a detecting method of an analog circuit is reduced and the digital signal processing parts 4a-4n are provided and perform processing in parallel, so the processing can be made fast.

摘要： PROBLEM TO BE SOLVED: To enlarge the wave front control range and to improve the compensation efficiency of a multidither system compensation optical device. SOLUTION: The device compensates for laser weave front distortion 3 generated from a laser resonator 1 by a shape varying mirror 5. The tilt components of the distortion 3 are compensated for by a tilt mirror 4 and other components are compensated for by a shape varying mirror 5. A controller 11 receives optical strength signals 10 obtained by detecting reflected waves 8 as inputs and the laser beams are phase modulated by the frequencies, that are different for every driving element, by the mirror 5 and the generated phase modulated signals are separated and detected. Each phase modulated signal is proportional to the laser phases of the driving element of the mirror 5. Thus, determinations are made for a displacement command 13 of the mirror 5 and an angular command 12 of a tilt mirror 4.

摘要： PURPOSE: To prevent reflected light from a laser beam irradiation surface of a beam from advancing into a lens barrel. CONSTITUTION: By painting the laser beam irradiation surface of the beam 15 with laser beam high absorption paint 18, a laser beam L is absorbed by the laser beam irradiation surface of the beam 15, so that the reflected light from the laser beam irradiation surface of the beam 15 is prevented from being multiply reflected in the lens barrel 4 and becoming stray light. Since the beam 15 is provided with a cooling path for making a cooling medium circulate in its interior, the heat of the beam 15 is taken away and the beam 15 is cooled by the cooling medium in a pipe even when the laser beam L is absorbed and the temperature of the beam 15 rises. As a result, the thermal deformation of the beam 15 caused by absorbing the laser beam is restrained.

摘要： PURPOSE: To prevent the deformation of the reflection mirror of a high power laser caused by the pressure of coolant. CONSTITUTION: A spiral shaped pipe 5 is embedded in a back plane 1b of a metallic mirror 1 through a packing material 6 having a high heat conductivity and a high elongation and contraction property. Having the above constitution, coolant R is not directly supplied to the plane 1b of the mirror 1. Rather, the coolant R is indirectly supplied to the plane 1b of the mirror 1 through the pipe 5. Thus, the corrosion of the mirror 1 by the coolant R is prevented, the deformation of the mirror 1 caused by the pressure of the coolant R is also prevented and a high surface precision of the mirror 1 is maintained.

摘要： PURPOSE:To judge the moving direction of the mirrors of a variable shape mirror in a multidither type compensating optical device by irradiating a laser on a target, and utilizing the phase delay between a dither signal contained in the reflective signal and an oscillator. CONSTITUTION:A compensating optical device is constituted of a laser, a variable shape mirror, a light converging device, a light detector, a synchronous wave detector, a control device, a variable shape mirror driving power source, and an oscillator, and it is a device to maximize the laser irradiation density on a target. For the purpose, the synchronous wave detector is provided with a phase delay detector 22 and a plus/minus sign discriminator 23 therein, for efficiently moving a plurality of mirrors of the variable shape mirror. It can be discriminated whether respective mirrors of the variable shape mirror are to be moved in the plus direction or the minus direction, by utilizing the phase delay. Further, the device can deal with a moving body, by providing a mechanism to measure the distance to a target and correct the phase delay due to the distance.

摘要： PROBLEM TO BE SOLVED: To reduce a number of charging and discharging of wiring between chips per one clock cycle to reduce a consumption power without using multi power sources, such as a multi potential transmission, and without using a high speed clock or a high speed delay control required for the pulse width modulation data transmission system.
SOLUTION: In a transmission side chip 30, a counter 34 outputs a count value obtained by up-counting the eight-multiplied clock CK8 of a clock CLK to a digital comparator 35. The digital comparator 35 outputs a high level signal when the counter value is equal to or more than a value of 3-bit transmitted data from flipflops 31 to 33. A selector 37 outputs a wave-like signal which performs amplitude transition once in rising or falling during one clock cycle. An output buffer 38 outputs the signal output from the selector 37 to an exterior penetrating wiring 50 of the transmission side chip 30.
