Description

technical field

[0001] The present invention relates to light emitters, light emitting devices, optical devices and information processing equipment. Background technique

[0002] JP-A-2018-32654 discloses that a vertical resonator type light emitting element module including a plurality of vertical resonator type light emitting elements arranged on a plane has a bonding surface provided on a substrate from mutual phase in a region between the laser beams of adjacent vertical resonator-type light emitting elements and on the emission direction side of the laser beams; and an outer wall facing a beam space through which the laser beams are transmitted.

[0003] Incidentally, light sources that perform three-dimensional sensing by the time-of-flight (ToF) method must switch large currents on and off at higher speeds in order to improve measurement accuracy. Therefore, when a wall supporting a diffusion plate that diffuses light from the light source is provided between the dr...

Embodiment approach

[0063] The information processing device recognizes whether access is permitted to the user accessing the information processing device, and in many cases, allows use of the device (information processing device) only if the authenticated user is a user who is permitted to access. So far, methods of authenticating users using passwords, fingerprints, irises, etc. have been employed. In recent years, an authentication method with higher security needs to be adopted. As this method, authentication using a three-dimensional image such as the shape of the user's face or the like is performed.

[0064] Here, as an example, an information processing device is described as a portable information processing terminal, and as a device that authenticates a user by recognizing the shape of a face captured as a three-dimensional image. In addition, the information processing device can also be applied to an information processing device such as a personal computer (PC) in addition to the ...
