Lens and Focusing Devices for Pyroelectric Infrared Sensors

A Fresnel lens both captures more IR radiation and focuses it to a small point. This focal point moves across the sensor as the IR source moves and exposes one element at a time. A Fresnel lens can extend detection range to about 100 feet. A Fresnel lens will give the best possible performance, however other devices can be used to extend range.

MAX25405 IR Gesture Sensor with Lens for Automotive ...

The proximity, hand detection, and gesture recognition functions of the MAX25405 operate by detecting the light reflected from the controlled IR-LED light source with an integrated 6x10-element optical sensor array. The MAX25405 can detect these gestures even when exposed to bright ambient light. A low-power, low-cost CPU, such as the MAX32630, is required to process the data from the sensor.

Problem with IR - Kolari Vision

Some older lenses used to account for this by providing an IR focus mark on the lens. In our conversions, we use filters with specific thicknesses to account for this change, and further fine tune the autofocus system. Unfortunately, the amount that focus shifts in a lens is not always constant between lenses, and on some lenses the autofocus is poor unless it is calibrated specifically to ...

IR (Infrared) Obstacle Detection Sensor Circuit

2015-02-02· An IR sensor consists of an IR LED and an IR Photodiode; together they are called as Photo – Coupler or Opto – Coupler. When the IR transmitter emits radiation, it reaches the object and some of the radiation reflects back to the IR receiver. Based on the intensity of the reception by the IR receiver, the output of the sensor is defined.

PIR Motion Sensor Tutorial : 8 Steps (with Pictures ...

When the sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. When a warm body like a human or animal passes by, it first intercepts one half of the PIR sensor, which causes a positive differential change between the two halves. When the warm body leaves the sensing area, the reverse happens, whereby the sensor generates a ...

The Correct Material for Infrared (IR) Applications

With this sensor, lens selection becomes important as the simultaneous imaging of both visible and IR light requires an IR corrected lens. This setup allows you to get the best of both worlds - you get IR without sacrificing color. The tradeoff with this technology is the color resolution as 1 green pixel is removed to get the IR component.

A lens hot spot is the most common problem encountered when shooting infrared light. They usually manifest in the form of a bright circle, sometimes in the shape of aperture leaves directly in the center of the image. The problem is exaggerated as you stop down (increase f stop number), with the spot becoming more prominent and defined. Hot spots can also behave differently in different zoom ...

Passive infrared sensor - Wikipedia

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion sensors are commonly used in security alarms and automatic lighting applications. PIR sensors detect general movement, but do not give information on who or what moved.

Infrared Temperature Sensor: what is it and how does it work?

2009-09-14· When an infrared temperature sensor measures an object’s temperature, consider the energy that actually enters the lens. That is, in addition to emitting energy related to its own temperature, the object may reflect energy coming from another source, or transmit energy passing through it from a source behind it. For accurate measurements, survey the surrounding area for possible sources of ...
