| PURPOSE: To achieve a higher performance by detecting the distance to an object existing within a detection area and the bearing and shape thereof. CONSTITUTION: A pulse signal light emitted from a light emitter is reflected from an object in a specified detection area and a reflected signal light is received with a photo detector having a light receiving section in which light receiving elements in a matrix. A distance detection means detrmines the distance to the object from a propagation delay time in the signal light until the reflected signal light was received with the photo detector after the signal light was emitted. A bearing detection means determines the bearing in which the object exists from the position of the light receiving element having received the reflected signal light among those arranged in the matrix and a shape detection means detects the shape of the object based on the mutually positional relationship of light receiving elements having received the reflected signal light.

| PURPOSE:To make it possible to largely take the deflecting angle of laser beam, by a method wherein two shafts having reflecting mirrors respectively attached thereto are revolved to make the reflecting mirror free in deflection to detect each deflecting angle. CONSTITUTION:Reflecting mirrors 10, 11 are attached to two shafts mutually crossed at right angles, for example, a horizontal shaft 13 and a vertical shaft 14 and these two shafts 13, 14 are respectively revolved by a motor 15 to make the reflecting mirros free in deflection. By this mechanism, each deflecting angle is detected by an encoder 17. As mentioned above, because a laser deflector E uses two reflecting mirrors made free in deflection, the deflecting angle of laser beam can be largely taken and the attenuation ratio of laser beam can be made small. | ||||||

| PURPOSE:To prevent misjudgement by interrupting discriminating operation of a judging circuit when an auxiliary detection light is projected to a part to be detected close to a main detection light or the reflected light thereof and reflected from a light shielding object. CONSTITUTION:A laser beam 4a from a main projection element 4 is received with a main light receiving element 8 reflected from a point 0 to be detected and provided to a discrimination circuit 11 via an A/D conversion circuit 10. Depending on whether the electrical signal is equal to, larger or smaller than the reference value preset and memorized in the discrimination circuit 11, the circuit determines the condition at the point, flat, concave or convex. When infrared rays 14a and 17a are projected to the point being detected from the auxiliary projection elements 14 and 17, there is little reflected light from the ground. A stick 24 traverses the laser beam 4a from the main projection element 4 and simultaneously the infrared beam 14a from the auxiliary projection element 14 and a reflection sheet wrapped on the stick reflects it. The laser beam thus reflected is received with the light receiving element 14 which outputs a stop signal to the discrimination circuit 11. This stops the operation of the discrimition circuit 11 temporarily to prevent misjudgement. | ||||||

| PURPOSE:To decide a material and a soil in the bottom of the sea, by a method wherein the bottom of the sea is irradiated with light with a wavelength of 2,000Angstrom -8,000Angstrom , and spectral distribution analyzer performs a spectrometry on light reflected by the material in the bottom of the sea, and its albedo curve is compared with that of a known material in the bottom of the sea. CONSTITUTION:A probing chip 1 is positioned on a sea surface above the bottom of the sea to be probed, and through operation of a winch connected to a probing device A, the device is suspended by means of a wire 2 in a suspension condition until the device A is lowered in close to the bottom of the sea. A condition of the device being suspended and moved in close to the bottom of the sea 7 can be observed in a ship by means of a submarine television camera 5. When it reaches a given probing position, and if the bottom of the sea 7 is irradiated through operation of a luminous device 3 from the inside of the ship, a collector 4 paired with the device 3 collects light reflected by a material in the bottom of the sea, it performs a spectrometry of a reflection absorption spectral distribution, it converts it into an electric signal to transmit it to a recorder 6 on the ship through a cable 2 by means of a telemeter, and this allows the formation of an albedo curve diagram. The curve is compared with a known albedo characteristics curve to decide a material in the bottom of the sea in a probing position. | ||||||

| PURPOSE:To rapidly and securely detect abnormal states such as a continuous dark state and a decrease in the quantity of light due to the deterioration of a light source and the sticking of dust, by realizing circuit constitution which employs both auto slicing and fixed slicing. CONSTITUTION:When a leadlet is conveyed to cut off light from a light source, light incident to a photodiode 3 is nearly eliminated, so an output voltage to an operational amplifier 14 drops. In response to variation in output voltage, an operational amplifier 19 outputs a light and dark binary-coded signal. If the paper gets congested on the front surface of a photodiode 13 to place the photodiode 13 in a continuously dark state, or if the operational amplifier 14 generates an abnormal voltage owing to a decrease in the quantity of light, etc., an automatic slice level generating circuit 23 does not operate normally, so a fixed slice level generating circuit 27 outputs a prescribed slice level as a substitute for said circuit 23, thus allowing the operational amplifier 19 to generates an output which shows the continuously dark state. Thus, an abnormal state is discriminated easily. | ||||||
