Abstract:
An optical unit is composed of transparent blocks (10a-10e) and dichroic films (11a-11d) which are different from one another in the wavelength range of reflectible lights. The transparent blocks (10a-10e) are aligned and joined while having the dichroic films (11a-11d) respectively interposed between adjacent two transparent blocks in such a manner that the dichroic films (11a-11d) are parallel to one another.
Abstract:
Un sac d'air (58) est utilisé sur un lit (10) à faible perte d'air. Le sac d'air (58) est pourvu d'un connecteur libérable qui retient le sac d'air (58) au lit (10) à faible perte d'air ainsi que d'un raccord (23) pour recevoir de l'air provenant d'un source d'alimentation en air de manière à gonfler le sac d'air (58). Le sac d'air (58) présente également un retrait (324) qui permet au patient (348) d'être roulé vers l'extrémité du sac d'air (58) lorsque ce dernier est gonflé. Un pilier (326) est prévu sur l'extrémité du sac d'air (58) vers lequel le patient (348) est roulé lorsque le sac d'air (58) est gonflé pour retenir le patient (348) sur le sac d'air (58). Les sacs d'air sont disposés en ensembles suivant une disposition d'alternance des sacs d'air (58) montés sur le cadre (12) du lit (10) à faible perte d'air de sorte que le patient est d'abord roulé dans une direction lorsque les sacs d'air (58) d'un ensemble sont gonflés puis dans le sens inverse lorsque les sacs d'air (58) du premier ensemble sont dégonflés et que les sacs d'air (58) du second ensemble sont gonflés.

Abstract:
A method and an apparatus for obtaining a full reflection spectrum are disclosed. The method for obtaining a full reflection spectrum first obtains an F-matrix from an image generated by picturing an object with a known full reflection spectrum by using the known full reflection spectrum, wherein the F matrix is formed by digitizing response characteristics of the camera, spectrum characteristics of an optical source, and a basis function for the full reflection spectrum. Then, a full reflection spectrum for a target object can be obtained using the F matrix which is pre-obtained from the image generated by picturing the target object, wherein the target object is illuminated by light according to a determined lighting environment.

PURPOSE: An NIR micro spectrometer is provided to reduce the size of a micro spectrometer while constantly maintaining the performance of the micro spectrometer by forming two fiber entrance slits. CONSTITUTION: An NIR micro spectrometer has a Paschen-Runge multiple spectrometer structure. The NIR micro spectrometer includes two fiber entrance slit(1,2), a concave grating(3) and PDA multiple photo detectors(5,6). Light outputted from the fiber entrance slit(1,2) is introduced into the concave grating(3) and the photo detector(5) through a wave guide(4). A semiconductor device(6) is provided instead of a photo detector and an outlet slit. An eccentric diffractive planar lens(7) is provided to sequentially distribute light into the fiber entrance slit(1,2). The fiber entrance slit(1,2) are installed at both sides of the PDA multiple photo detectors(5,6).

Abstract:
PURPOSE: A rotating high-speed multichannel multiple beam spectrophotometer is provided to sequentially measuring luminous intensity of beams of various wavelengths by splitting incidence beams depending on wavelengths. CONSTITUTION: A grating(18) is fixed on a rotating shaft in a cylindrical spectroscope(15), and the rotating shaft is rotates at a specific speed by a precise motor. The reflective grating connected to the rotating shaft spatially splits the beam incident from optical fiber(12) depending on wavelengths and reflects the split beam to an optical sensor. Wavelength of the beam reaching the optical sensor is various depending on the rotational angle of the motor. Spectrums of the entire wavelengths of incidence beams are measured. By connecting many incidence beams to the upper and lower parts of the spectroscope, spectrums are measured by optical sensors.
