An optical system for immersion underwater in an aquaculture environment. The optical system captures, in situ, digital images of underwater objects such as freely swimming fish such as, for example, sea salmon or sea trout, as the fish swim naturally in the aquaculture environment. The digital images produced by the optical system are of enough quality such that reliable detection of sea lice in different life stages by a human visual inspection of the digital image or by computer vision systems is enabled.

Optical system for capturing digital images in an aquaculture environment in situ

A sensor, optical system, and combination lens for use with an optical sensor are disclosed. An illustrative optical system is described to include a photodetector having a proximity sensor area and an ambient light sensor area that is physically separated from the proximity sensor area as well as a combination lens that includes a proximity sensor focusing portion and an ambient light sensor focusing portion that each separately direct incident light for the proximity sensor area and the ambient light sensor area, respectively.

Combination lens including an ambient light sensor portion and a proximity sensor portion for proximity sensing and ambient light sensing

An optical sensor, optical system, and proximity sensor are disclosed. An illustrative proximity sensor is disclosed to include a light source and a photodetector including a photo-sensitive area that receives incident light and converts the received incident light into an electrical signal. The light source and photodetector are positioned diagonally relative to one another, thereby enabling the devices to be positioned closer together on a body or substrate.

Miniaturized optical proximity sensor

A proximity sensing device having an emitter die, a receiver die, a body is disclosed. The proximity sensor has an optical structure provided on the body. The optical structure may provide an optical path to allow radiation reflected by a near object that may be otherwise blocked by the body to be transmitted towards the receiver die. In addition to the proximity-sensing device, a sensing device having at least two trenches that allow close proximity sensing is disclosed. A method for sensing an object that involve determining whether the object correspond to a near object or a far object is presented.

Proximity-sensing device

An optical assembly can be used in various optical devices such as optical proximity sensors, gesture sensors, or imaging sensors. The optical assembly may include a lens assembly and a light detector. The lens assembly may be configured to limit off axis rays at a central area of the light detector. The lens assembly can be a high aspect ratio lens assembly.

Cone shaped focusing lens

An optical sensor for detecting at least one of proximity and gesture is disclosed. The optical sensor is configured to detect or sense an object that is located out of the sensor's primary axis. This off-axis detection is facilitated by projecting light emitted by a light source away from the sensor's primary axis and away from the direction in which the light was originally emitted by the light source. The light detector is also configured to detect the light that is being projected off-axis.

Off-axis detection for proximity or gesture sensor

In one embodiment, an optical device comprising an emitter, first and second emitter optical elements and a receiver is disclosed. The emitter and the receiver may be arranged substantially along a longitudinal axis. The first and second emitter optical elements may be interposing the longitudinal axis. One other embodiment discloses an optical device comprising an emitter and a receiver arranged on a longitudinal axis. The optical device may further comprise first and second emitter optical elements arranged along an axis orthogonal to the longitudinal axis but interposing the longitudinal axis. In another embodiment, a proximity sensor having first and second emitters interposing a longitudinal axis is disclosed.
