摘要： In an optical movement information detector, light emitted from a laser diode (1) is split into a first beam (10), a second beam (11) and a third beam (12) by beam splitters (2a, 2b). The first, second and third beams are converged by a condenser lens (4) upon a surface of an object to be measured (5) to form a beam spot (13) thereon. Diffused light from the beam spot (13) is received by a photodiode (6) and an output signal of the photodiode (6) is processed by a signal processing circuit (20) including an analog-digital converter (8) and a Fourier transforming unit (9). A detecting section (21) obtains, for example, a moving velocity and a moving direction of the object based on spectrum peak frequencies obtained by the Fourier transform.

摘要： In the color information measuring device, the print object information measuring device, the printing device and the electronic equipment, three light fluxes of mutually different wavelengths applied to a measurement object from a red LED, a green LED and a blue LED of a light-emitting part have a common illumination area on the measurement object. The common illumination area on the measurement object contains such an observation area on the measurement object that a reflected ray is made to be incident on a photodiode via a condenser lens and a slit member. Therefore, the common illumination area in which three light fluxes of different wavelengths overlap with one another can reliably be made to be an observation area, so that intensities of a plurality of reflected rays of different wavelengths derived from the observation area can be observed equivalently, hence an improved measurement accuracy.

摘要： Two different phase components obtained by splitting interference light of light from an object by a diffraction grating are guided to first and second PD's by a second optical system. A first signal is outputted from a first signal processing circuit section that receives light reception signal from first PD, and a second signal is outputted from a second signal processing circuit section that receives a light reception signal from the second PD. A third signal of an interference light signal whose noise component is removed is outputted by a third signal processing circuit section using the first signal and the second signal. Then, the frequency of the third signal is detected, and the movement velocity of the object is detected by a movement velocity detection section on the basis of the frequency.

摘要： A first luminous flux emitted from the front end face of a LD is reflected by a mirror to be made incident on a detection point on the surface of a measuring object, and a second luminous flux emitted from the rear end face of the LD is reflected by another mirror to be made incident on the detection point. Scattered light from the first detection point is received in a photodiode. A signal processing circuit part calculates the frequency shift quantity of the scattered light based on output from the photodiode. As a result, a velocimeter is provided which detects the moving speed of a measuring object highly precisely.
