Abstract: According to an aspect, a detection apparatus includes: an optical sensor including a sensor base member and a plurality of photoelectric conversion elements that are provided on the sensor base member and each of which is configured to output a signal corresponding to light emitted to the photoelectric conversion element; and a lighting device including a plurality of first light-emitting elements configured to emit first light having a first maximum emission wavelength and a plurality of second light-emitting elements configured to emit second light having a second maximum emission wavelength. Each of the photoelectric conversion elements has responsivity in a wavelength region including a wavelength region of the first light and a wavelength region of the second light.

Abstract: Provided are PHA particles which are excellent in dispersibility in an aqueous dispersion and have excellent film formation capability, in which odor of a molded body obtained from the PHA particles or an aqueous dispersion of the PHA particles is suppressed, and whose color tone is good, and an aqueous dispersion of the PHA particles. Polyhydroxyalkanoate particles including polyhydroxyalkanoate having a particle shape and peptidoglycan covering a portion of or an entire surface of the polyhydroxyalkanoate. In this polyhydroxyalkanoate particle, a content of polyhydroxyalkanoate is 98.0% by weight or more, and a content of peptidoglycan is 0.1% by weight or more and 1.0% by weight or less.
