PROBLEM TO BE SOLVED: To provide an optical delay device capable of enhancing measuring precision. SOLUTION: The signal output from a terahertz wave detecting part at every pulse interval of pulse light is taken in so as to be synchronized to a pulse signal showing that graduations of an equal interval arranged along the moving direction of a movable stage movable in a direction shortening or extending the light path length of the incident pulse light are detected.

Abstract:
The present invention provides a spectrometer, comprising: an inlet for the receipt of incident light; an optical path for transmitting the incident light from the inlet to an analysis plane; a focusing element located along the optical path, wherein the spectrometer has an in-focus position in which a focal point of the spectrometer and the analysis plane coincide; and a controller adapted in use, when a removable light disperser is placed along the optical path, to cause the spectrometer to be in the in- focus position by controlling the position of the focusing element relative to the analysis plane. The spectrometer is used in the analysis of light from a light source and, due to the ability of the controller to manage the focus point by way of moving the focusing element, the spectrometer is able to bring itself into an in-focus configuration without the need for a user to intervene.

Abstract:
A spectrometry instrument, e.g., for time-resolved spectroscopy, has quick-change exchangeable accessories (48, 50, 52) which are manually attached via rotation of a camming means to engage and lock a stud member. A circuit element in each accessory (48, 50, 52), such as a resistor or a configured pin connection, acts to generate a voltage in the instrument that uniquely identifies which accessory is attached. A method for measuring a phosphorescence decay characteristic includes applying an excitation pulse to a sample (34); obtaining emission intensity data for a sequence of time delays following the excitation pulse; repeating for at least one further excitation pulse using a different sequence of time delays; and interleaving the data from different excitation pulses to construct a decay characteristic.
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.
Abstract:
PURPOSE: A camera with a spectrometric sensor is provided to apply various fields and to reducing a size and costs. CONSTITUTION: An image is reflected in a color image sensor(110). The same image reflected in the color image sensor passes through a diffuser(121). The same image passed is reflected through a beam splitter(150) in a spectrometric sensor(120). The diffuser is installed in between the spectrometric sensor and the beam splitter.
