String updated in the repository

Detect small frequency shifts of the Doppler effect.

You need a tone generator that emits a constant frequency (for example 1000Hz from a second phone). Enter this base frequency in the experiment's setup. The experiment will determine the recorded frequency and calculate the relative speed of the sound source.

Détecte les petits décalages de fréquence dus à l’effet Doppler.

Il vous faut un générateur qui émet un son à une fréquence constante (par exemple 1000 Hz). Entrez cette fréquence de référence ainsi que la plage autour de cette référence dans laquelle l'expérience devra travailler (par exemple 10 Hz). L'expérience déterminera la fréquence du son reçu et calculera la vitesse relative de la source sonore.

You need a tone generator that emits a constant frequency (for example 1000Hz from a second phone). Enter this base frequency in the experiment's setup and select a detection range in which you expect the Doppler shifted frequency (for example 10Hz). The experiment will determine the recorded frequency and calculate the relative speed of the sound source.

Measures distances through echoes and the speed of sound.

A sonar sends out sound, which gets reflected by the object you want to measure. As sound travels at a speed of approximately 340 m/s, the time until the reflection reaches the microphone of your phone can be used to calculate the distance of this object.

This experiment continuously plays a short "chirp", a sound sweeping from 2 kHz to 10 kHz, repeated about 23 times per second, and records at the same time. A crosscorrelation of the chirp and the recorded data gives information about the timing at which echoes occur. Several chirps are averaged for each result. The strongest signal is the sound traveling directly from the speaker to the microphone and all echoes are timed relative to it. This timing can then be multiplied with the speed of sound (and divided by 2 as the sound has to travel forth and back) and you get the distance at which the echo originated.

However, sound usually travels in every direction. For a sonar this means, that when targeting a wall, you also get reflections from the floor, the ceiling, another wall nearby, a post and simply from every suitable "hard" surface nearby. Therefore this sonar gives you all the reflections and it is up to you to interpret the result and to figure out, which reflection corresponds to the target you intended to measure. So start with a small hard target and try to screen all other directions with some foam material. Also, this needs a quiet environment.

Mesure une distance en utilisant l’écho.

Un sonar envoie des pulses sonores qui sont réfléchis par l'objet dont vous voulez mesurer la distance. Le son se déplace à une vitesse d'environ 340 m/s ; le temps qui sépare l’émission du pulse et le retour de son écho (mesuré par le microphone de votre téléphone) peut être utilisé pour calculer la distance de cet objet.

Cette expérience génère un « pulse » dans le haut-parleur de votre smartphone, et démarre un enregistrement sonore. Une corrélation croisée entre le pulse émis et le son mesuré permet de déterminer le moment quand l’écho revient sur le micro. Ce temps peut ensuite être multiplié par la vitesse du son (et divisé par 2 car le son fait un aller-retour) pour obtenir la distance à laquelle se trouve l’objet responsable de la réflexion du pulse sonore.

Cependant le son voyage dans toutes les directions. En ciblant un mur, vous obtenez également des réflexions en provenance du sol, du plafond, des autres murs, et de toute surface « dure » située à proximité. Le sonar mesure tous les échos, et c'est à vous d'interpréter le résultat et de déterminer quelle réflexion correspond à la cible que vous voulez mesurer. Commencez par une petite cible en matière dure et essayez de protéger les autres directions avec de la mousse. Un environnement bruyant va perturber cette expérience.

Enter the frequency of your tone generator as base frequency. A shorter time step gives more values per second, a longer one gives more precise values. Values are only shown while the tone is clearly recognizable and stays within a few hundred hertz of the base frequency.

Using a known light source, you can tap the graph, select the calibrate mode at the bottom and pick peaks to match them with known wavelengths. You can then see the calibrated spectrum on tab 3.
Utilisez une source de lumière dont vous connaissez le spectre pour cette étape de calibration. Cliquez sur le graph, et choisissez le mode "Étalonner", en bas de l'écran. Définissez les longueurs d'onde de deux points que vous choisissez. Le spectre lumineux calibré à partir de ces deux points est affiché dans l'onglet "3 - Spectre".

The raw data from the camera is converted to RGB and the individual RGB channels are linearized assuming the gamma curve of sRGB, and then converted to luma. The relative luminance is the luma value normalized to the camera settings such that a pure white image yields a relative luminance of 1 if the camera is set to an exposure time of 1/60s, an ISO of 100 and an aperture of f/1 (Note that this still does not allow for comparison across different models.).
Les données brutes de la caméra sont converties au format RVB, puis les canaux RVB individuels sont linéarisés à partir du gamma du sRGB, avant d'être convertis en luminance. La luminance relative est la valeur de luminance normalisée par rapport aux réglages de l'appareil photo, de telle sorte qu'une image d'un blanc pur donne une luminance relative de 1 si l'appareil photo est réglé sur un temps d'exposition de 1/60 s, une sensibilité ISO de 100 et une ouverture de f/1 (cette normalisation ne permet cependant pas toujours de comparer les mesures de différents modèles de smartphone entre elles).
