Abstract: A biometric apparatus includes a light source, an image sensor, a control circuit, and a signal processing circuit. The control circuit causes a light source to repeatedly emit a light pulse radiated onto a target part including a head of a target, causes an image sensor to receive a reflected light pulse which is caused as the light pulse is radiated onto the target part, causes the image sensor to output first image data indicating appearance of a face of the target, and causes the image sensor to output second image data according to distribution of an amount of light of at least one of components of the reflected light pulse. The signal processing circuit generates data indicating a state of the target based on a temporal change in the first image data and a temporal change in the second image data and outputs the data.

Abstract: A photodetection device including an image sensor that includes fifth pixels and sixth pixels; an interference element that includes fifth incident regions; and illumination that emits light in a first wavelength band and a second wavelength band. The interference element causes first interference of light in the first wavelength band incident on two fifth incident regions, and guides resultant light of the first interference to any of the fifth pixels and guides another part of the light in the first wavelength band to any of the sixth pixels, and causes second interference of part of the light in the second wavelength band incident on the two fifth incident regions, and guides resultant light of the second interference to any of the fifth pixels and guides another part of the light in the second wavelength band incident on the two fifth incident regions to any of the sixth pixels.

Abstract: The present application discloses a detecting apparatus including: a light source for emitting excitation light; a storage portion in which a specimen is stored; a metal film which receives the excitation light to cause evanescent light for illuminating the specimen; a modulator for adjusting an incident angle of the excitation light on the metal film; a driver for generating a driving signal for driving the modulator; a detector for outputting a fluorescence signal in correspondence to intensity of fluorescence generated from the specimen under irradiation of the evanescent light; and an extractor which extracts a signal component from the fluorescence signal, the signal component deriving from the specimen. The incident angle changes in response to a change of the driving signal. The extractor extracts a synchronous signal component as the signal component, the synchronous signal component changing in synchronization with the change of the driving signal.
