摘要： A hologram of an increased size using a single color laser, capable of executing a full color regeneration in a desired view angle and a method for producing the hologram. A plurality of photo-sensitive members are independently exposed to obtain respective holograms, which are connected by using an adhesive layer 80 constructing a connecting means, in order to obtain an integrated hologram expanded in two-dimensional direction. The holograms are obtained by an interference of a reference light 22 and an object light passed through a light diffusing body 24 in order to cause the light diffusing body 24 to be recorded on the photo-sensitive member. The size of the light diffusing body 24 is such that the spectral characteristic of the diffused light from the hologram can attain a desired efficiency at least over the entire wavelength range of the visible light.

摘要： When a driver of a vehicle brings his/her detection part close to a case, a sensor detects a pulse of the driver at the detection part with an optical method, and takes an image of the detection part. An individual certification means determines whether the driver of the vehicle is an authorized person or not based on the image of the detection part taken by the sensor. An alcohol concentration determiner calculates an index value of a blood alcohol concentration of the driver based on the pulse detected at the detection part by the sensor, and determines whether the index value exceeds a criterial value of a drinking assessment. When it is determined that the driver of the vehicle is an authorized person and the index value does not exceed the criterial value of the drinking assessment, a permission means permits the driver to start an engine of the vehicle.

摘要： An infrared rays detection apparatus including an optical window member having a characteristic that scatters noise light, which is capable of reducing an influence of noise light with a simple structure. An infrared rays detection apparatus includes: a condenser lens; an infrared rays image sensor made up of plural thermal detection elements; and a signal detection/process circuit (SDP circuit). The image sensor detects a thermal distribution of a predetermined area condensed by the condenser lens in a passenger room. The SDP circuit makes a thermal image data based on the thermal distribution detected by the image sensor. Various types of system control circuits control each of the vehicular system as described later based on the thermal image data provided from the SDP circuit. The condenser lens is formed so that noise light such as visible light is scattered thereby and that infrared rays is transmitted therethrough to the image sensor. Furthermore, when all temperatures detected by all of the thermal detection elements uniformly rise, the SDP circuit determines that scattered visible light is entered and than makes obtained data invalid.

摘要： An optical pulse wave detection apparatus includes a light emitting element, a light receiving element, a first control unit, a second control unit, and a pulse wave detection unit. The first control unit obtains a first signal by causing the light emitting element to emit light of a first light quantity, and by causing the light receiving element to receive reflected light, which is reflected by a living organism, of the light of the first light quantity. The second control unit obtains a second signal by causing the light emitting element to emit the light of a second light quantity that is smaller than the first light quantity, and by causing the light receiving element to receive the reflected light of the light of the second light quantity. The pulse wave detection unit detects a pulse wave of the living organism based on the first and second signals.

摘要： In a vehicle air conditioning system, a non-contact temperature sensor having plural temperature detecting elements is disposed to detect a predetermined region within a passenger compartment. The plural temperature detecting elements are constructed by plural first elements each of which has a smaller temperature detecting area in the predetermined region, and plural second elements each of which has a larger temperature detecting area in the predetermined region. The non-contact temperature sensor detects an area, where a detail temperature-distribution information is necessary, using the first elements, and detects an area, where the detail temperature-distribution information is unnecessary, using the second elements.
