Abstract: Methods for wavelength determination of a monochromatic beam are described. The methods involve a detector unit containing at least one variable filter and at least one pair of photo detectors. The detectors have photo sensitive regions with their areas varying with the position in one direction. The wavelength for maximum transmission of the variable filter varies in the same direction. By comparing the photo current values from the two detectors, wavelength of the incident beam is determined. Methods to construct wavelength discrimination junction photo detector pair and double barrier photo detector pair are also given.

Abstract: An image pickup device providing favorable images which effectively suppress the interference stripe noise originating in the interference stripes created on an image sensor surface of the image pickup device. The image pickup device includes an image sensor 3 and an overlying lid glass 2. By providing a prescribed inclination angle with respect to the relative position of the image sensor 3 and the lid glass 2 protecting it, the same number of interference stripes are provided with respect to each constitutional image-defining element within the image sensor 3, and prevention of interference stripe noise is achieved by leveling the average light intensity each constitutional image-defining element receives so that sensitizing of interference stripe noise does not occur at the specific elements.

Abstract: A photoelectric sensor comprises a thin plate-shaped optical body, a circuit block and a casing for incorporating therein the optical body and the circuit block. A nearly infrared light incoming through a front surface of the casing is reflected upon a first reflective surface of the optical body. Following this first reflection, a second reflection is made upon a second reflective surface thereof. The light having passed through a light collective lens is received by a photoelectric converting element and converted into electric signals for output. Since the optical body comprises a plurality of reflective surfaces, an optical path up to the photoelectric converting element can be incorporated compactly within the thin plate-shaped optical body.

Abstract: A proximity sensing device includes: a light source, a sensing unit, a light guide unit, and a window. The light source emits light, which is guided by the light guide unit to the window. The emitted light reflected by an object is received by the same window. The light guide unit includes a partial-transmissive-partial-reflective (PTPR) optical element, whereby the light emitted from the light source is reflected by the PTPR optical element, while the light reflected by the object passes through the PTPR optical element. There is only one window required.
