Abstract: In each of a first phase shift differential image produced in the absence of a subject in preliminary imaging and a second phase shift differential image produced in the presence of the subject in main imaging, boundaries, at each of which a value changes from π/2 to −π/2 or from −π/2 to π/2, are determined. First and second staircase data in each of which a value changes by π or −π when crossing each of the boundaries in a predetermined direction is produced. The first and second staircase data is added to the first and second phase shift differential images to produce first and second added phase shift differential image, respectively. The first added phase shift differential image is subtracted from the second added phase shift differential image to produce a corrected phase shift differential image.

Abstract: A Q switch is vibrated by applying a first voltage, and pulsed laser light is emitted by applying a second voltage to the Q switch at a point in time at which a preset delay time has passed from the start of emission of excitation light. Then, in this case, a time which is within a period, for which the vibration of the Q switch continues, and at which the intensity of the pulsed laser light periodically changing due to the vibration of the Q switch is maximized in a case where a point in time of application of the second voltage to the Q switch is changed is set as the delay time.

Abstract: A solid-state laser device includes a resonator composed of a pair of mirrors, a laser rod disposed in the resonator, and a laser chamber. The resonator and the laser rod are disposed in a housing. The laser rod is inserted through a hole of the laser chamber and is supported in a state in which two end portions are exposed. An O-ring is disposed at an exposed root of at least one rod end portion exposed from the laser chamber. The solid-state laser device includes a cover member that is disposed on a rod side surface of the rod end portion between the O-ring and a rod end surface and that blocks incidence of stray light, which is generated in the housing, on the O-ring.

Abstract: Provided is a solid-state laser device in which a linear resonator including an output mirror and a rear mirror, a laser rod, and optical members are provided on a common base and are contained in a housing having the base as a portion. A holding part is provided to hold an excitation light source that extends parallel to the laser rod on a side of the laser rod opposite to the base. The optical members including a Q-switch are disposed between the laser rod and the rear mirror. An upper end position of the output mirror is at a position lower than a lower end position of the excitation light source held by the holding part, with the base as a reference. The holding part holds the excitation light source so as to be capable of being inserted and extracted with respect to the output mirror side in a longitudinal direction of the excitation light source.

Abstract: A radiation imaging apparatus includes a differential phase image producing section, a phase unwrapping section, a statistical operation section, and a correction processing section. The differential phase image producing section produces a differential phase image in which pixel values are wrapped into a predetermined range α. The phase unwrapping section performs a phase unwrapping process to the differential phase image. The statistical operation section obtains a mode from statistical operation of pixel values in each subregion segmented in the unwrapped differential phase image. Each subregion is a unit in which error caused by the phase unwrapping process is to be corrected. The correction processing section calculates, for each pixel, an integer “n” which allows a difference Δ between the mode and a pixel value of each pixel to satisfy nα−α/2≦Δ
